10 Reference Manual 308017EN, Edition 1/Rev. B Rosemount Tank Radar REX October 2007 Chapter 2 Safety 2. Safety TankRadar REX equipment is often used in areas where flammable materials are handled and where an explosive atmosphere may be present. To protect both the plant and the personnel, precautions must be taken to ensure that this atmosphere cannot be ignited. These areas are called hazardous areas and equipment within these areas must be explosion protected. A number of different explosion protection techniques have been developed over the years. Intrinsic safety and explosion proof (or flame proof ) safety are two techniques. 2.1 Intrinsic Safety Intrinsic safety, IS, is based on the principle of restricting electrical energy available in hazardous-area circuits such that any sparks or hot surfaces, that may occur as a result of electrical faults in components, are unable to cause ignition. Intrinsic safety is the only technique accepted for Zone 0 hazardous areas. It is also safe for personnel and allows equipment to be maintained without the need for a gas-free certificate. The basic principles of intrinsic safety are: All flammable materials are grouped according to the energy needed to ignite them. Equipment located in hazardous areas are classified according to the maximum surface temperature that it can produce and this must be safe with the flammable gases that may be present. Hazardous areas are classified according to the probability that an explosive atmosphere is present, and this dictates whether or not a particular explosion protection technique may be used. Note! For trouble shooting and repair work of components in or in connection to intrinsically safe equipment, strict observance of the following rules is necessary: - Disconnect the power supply to the Radar Tank Gauge. - Use a certified battery operated instrument only. - Use Rosemount TankRadar REX original spare parts only. Replacement with non-original spare parts may jeopardize the intrinsic safety. 2-1

11 Reference Manual Rosemount Tank Radar REX 308017EN, Edition 1/Rev. B Chapter 2 Safety October 2007 2.2 Explosion Proof Explosion proof enclosures can be used when an explosion can be allowed inside the enclosure as long as it does not spread to the outside. The enclosure must be strong enough to withstand the pressure and must have narrow gaps to allow the pressure to escape without igniting the atmosphere outside of the equipment. Note! Any substitution to non-recognized parts may impair safety. The explosion-proof (flame-proof ) enclosure of the Gauge Head must not be opened while the unit is powered. 2-2

18 Reference Manual 308017EN, Edition 1/Rev. B Rosemount Tank Radar REX October 2007 Chapter 3 FOUNDATION Fieldbus Technology and 3. FOUNDATION Fieldbus Technology and Fieldbus Function Blocks 3.1 Overview This section introduces fieldbus systems that are common to all fieldbus devices. 3.2 Introduction A fieldbus system is a distributed system composed of field devices and control and monitoring equipment integrated into the physical environment of a plant or factory. Fieldbus devices work together to provide I/O and control for automated processes and operations. The FOUNDATION fieldbus provides a framework for describing these systems as a collection of physical devices interconnected by a fieldbus network. One of the ways that the physical devices are used is to perform their portion of the total system operation by implementing one or more function blocks. 3.2.1 Function Blocks Function blocks within the fieldbus device perform the various functions required for process control. Because each system is different, the mix and configuration of functions are different. Therefore, the FOUNDATION fieldbus has designed a range of function blocks, each addressing a different need. Function blocks perform process control functions, such as analog input (AI) and analog output (AO) functions as well as proportional-integral- derivative (PID) functions. The standard function blocks provide a common structure for defining function block inputs, outputs, control parameters, events, alarms, and modes, and combining them into a process that can be implemented within a single device or over the fieldbus network. This simplifies the identification of characteristics that are common to function blocks. The FOUNDATION fieldbus has established the function blocks by defining a small set of parameters used in all function blocks called universal parameters. The FOUNDATION fieldbus has also defined a standard set of function block classes such as: input, output, control, and calculation blocks. Each of these classes also has a small set of parameters established for it. They have also published definitions for transducer blocks commonly used with standard function blocks. Examples include temperature, pressure, level, and flow transducer blocks. 3-1

19 Reference Manual Rosemount Tank Radar REX 308017EN, Edition 1/Rev. B Chapter 3 FOUNDATION Fieldbus Technology and October 2007 The FOUNDATION specifications and definitions allow vendors to add their own parameters by importing and subclassing specified classes. This approach permits extending function block definitions as new requirements are discovered and as technology advances. Figure 3-1 illustrates the internal structure of a function block. When execution begins, input parameter values from other blocks are snapped-in by the block. The input snap process ensures that these values do not change during the block execution. New values received for these parameters do not affect the snapped values and will not be used by the function block during the current execution. Input Events Execution Output Events Control FF_BLOCKINTERNALSTRUCTURE Input Input Processing Output Parameter Output Parameter Snap Algorithm Snap Linkages Linkages Status Status Figure 3-1. Function Block Internal Structure Once the inputs are snapped, the algorithm operates on them, generating outputs as it progresses. Algorithm executions are controlled through the setting of contained parameters. Contained parameters are internal to function blocks and do not appear as normal input and output parameters. However, they may be accessed and modified remotely, as specified by the function block. Input events may affect the operation of the algorithm. An execution control function regulates the receipt of input events and the generation of output events during execution of the algorithm. Upon completion of the algorithm, the data internal to the block is saved for use in the next execution, and the output data is snapped, releasing it for use by other function blocks. A block is a tagged logical processing unit. The tag is the name of the block. System management services locate a block by its tag. Thus the service personnel need only know the tag of the block to access or change the appropriate block parameters. Function blocks are also capable of performing short-term data collection and storage for reviewing their behavior. 3-2

20 Reference Manual 308017EN, Edition 1/Rev. B Rosemount Tank Radar REX October 2007 Chapter 3 FOUNDATION Fieldbus Technology and 3.2.2 Device Descriptions Device Descriptions are specified tool definitions that are associated with the function blocks. Device descriptions provide for the definition and description of the function blocks and their parameters. To promote consistency of definition and understanding, descriptive information, such as data type and length, is maintained in the device description. Device Descriptions are written using an open language called the Device Description Language (DDL). Parameter transfers between function blocks can be easily verified because all parameters are described using the same language. Once written, the device description can be stored on an external medium, such as a CD-ROM or diskette. Users can then read the device description from the external medium. The use of an open language in the device description permits interoperability of function blocks within devices from various vendors. Additionally, human interface devices, such as operator consoles and computers, do not have to be programmed specifically for each type of device on the bus. Instead their displays and interactions with devices are driven from the device descriptions. Device descriptions may also include a set of processing routines called methods. Methods provide a procedure for accessing and manipulating parameters within a device. 3.3 Block Operation In addition to function blocks, fieldbus devices contain two other block types to support the function blocks. These are the resource block and the transducer block. The resource block contains the hardware specific characteristics associated with a device. Transducer blocks couple the function blocks to local input/output functions. 3.3.1 Instrument-Specific Function Blocks Resource Blocks Resource blocks contain the hardware specific characteristics associated with a device; they have no input or output parameters. The algorithm within a resource block monitors and controls the general operation of the physical device hardware. The execution of this algorithm is dependent on the characteristics of the physical device, as defined by the manufacturer. As a result of this activity, the algorithm may cause the generation of events. There is only one resource block defined for a device. For example, when the mode of a resource block is out of service, it impacts all of the other blocks. 3-3

21 Reference Manual Rosemount Tank Radar REX 308017EN, Edition 1/Rev. B Chapter 3 FOUNDATION Fieldbus Technology and October 2007 Transducer Blocks Transducer blocks connect function blocks to local input/output functions. They read sensor hardware and write to effector (actuator) hardware. This permits the transducer block to execute as frequently as necessary to obtain good data from sensors and ensure proper writes to the actuator without burdening the function blocks that use the data. The transducer block also isolates the function block from the vendor specific characteristics of the physical I/O. 3.3.2 Alerts When an alert occurs, execution control sends an event notification and waits a specified period of time for an acknowledgment to be received. This occurs even if the condition that caused the alert no longer exists. If the acknowledgment is not received within the pre-specified time-out period, the event notification is retransmitted. This assures that alert messages are not lost. Two types of alerts are defined for the block, events and alarms. Events are used to report a status change when a block leaves a particular state, such as when a parameter crosses a threshold. Alarms not only report a status change when a block leaves a particular state, but also report when it returns back to that state. 3-4

22 Reference Manual 308017EN, Edition 1/Rev. B Rosemount Tank Radar REX October 2007 Chapter 3 FOUNDATION Fieldbus Technology and 3.4 Network communication Figure 3-2 illustrates a simple fieldbus network consisting of a single segment (link). FF_NETWORKCOMMUNICATIO Fieldbus Link LAS Link Master Basic Devices and/or link master devices LAS = Link Active Scheduler Figure 3-2. Simple, Single-Link Fieldbus Network 3.4.1 Link Active Scheduler (LAS) All links have one and only one Link Active Scheduler (LAS). The LAS operates as the bus arbiter for the link. The LAS does the following: recognizes and adds new devices to the link. removes non-responsive devices from the link. distributes Data Link (DL) and Link Scheduling (LS) time on the link. Data Link Time is a network-wide time periodically distributed by the LAS to synchronize all device clocks on the bus. Link Scheduling time is a link-specific time represented as an offset from Data Link Time. It is used to indicate when the LAS on each link begins and repeats its schedule. It is used by system manage- ment to synchronize function block execution with the data trans- fers scheduled by the LAS. polls devices for process loop data at scheduled transmission times. distributes a priority-driven token to devices between scheduled transmissions. Any device on the link may become the LAS, as long as it is capable. The devices that are capable of becoming the LAS are called link master devices. All other devices are referred to as basic devices. When a segment first starts up, or upon failure of the existing LAS, the link master devices on the segment bid to become the LAS. The link master that wins the bid begins operating as the LAS immediately upon completion of the bidding process. Link masters that do not become the LAS act as basic devices. However, the link masters can act as LAS backups by monitoring the link for failure of the LAS and then bidding to become the LAS when a LAS failure is detected. 3-5

23 Reference Manual Rosemount Tank Radar REX 308017EN, Edition 1/Rev. B Chapter 3 FOUNDATION Fieldbus Technology and October 2007 Only one device can communicate at a time. Permission to communicate on the bus is controlled by a centralized token passed between devices by the LAS. Only the device with the token can communicate. The LAS maintains a list of all devices that need access to the bus. This list is called the Live List. Two types of tokens are used by the LAS. A time-critical token, compel data (CD), is sent by the LAS according to a schedule. A non-time critical token, pass token (PT), is sent by the LAS to each device in ascending numerical order according to address. 3.4.2 Device Addressing Fieldbus uses addresses between 0 and 255. Addresses 0 through 15 are reserved for group addressing and for use by the data link layer. For all Emerson Process Management, Rosemount Division fieldbus devices addresses 20 through 35 are available to the device. If there are two or more devices with the same address, the first device to start will use its programmed address. Each of the other devices will be given one of four temporary addresses between 248 and 251. If a temporary address is not available, the device will be unavailable until a temporary address becomes available. 3.4.3 Scheduled Transfers Information is transferred between devices over the fieldbus using three different types of reporting. Publisher/Subscriber: This type of reporting is used to transfer critical process loop data, such as the process variable. The data producers (publishers) post the data in a buffer that is transmitted to the subscriber (S), when the publisher receives the Compel data. The buffer contains only one copy of the data. New data completely overwrites previous data. Updates to published data are transferred simultaneously to all subscribers in a single broad- cast. Transfers of this type can be scheduled on a precisely peri- odic basis. Report Distribution: This type of reporting is used to broadcast and multicast event and trend reports. The destination address may be predefined so that all reports are sent to the same address, or it may be provided separately with each report. Trans- fers of this type are queued. They are delivered to the receivers in the order transmitted, although there may be gaps due to cor- rupted transfers. These transfers are unscheduled and occur in between scheduled transfers at a given priority. Client/Server: This type of reporting is used for request/response exchanges between pairs of devices. Like Report Distribution reporting, the transfers are queued, unscheduled, and prioritized. Queued means the messages are sent and received in the order submitted for transmission, according to their priority, without over- writing previous messages. However, unlike Report Distribution, 3-6

24 Reference Manual 308017EN, Edition 1/Rev. B Rosemount Tank Radar REX October 2007 Chapter 3 FOUNDATION Fieldbus Technology and these transfers are flow controlled and employ a retransmission procedure to recover from corrupted transfers. Figure 3-3 diagrams the method of scheduled data transfer. Scheduled data transfers are typically used for the regular cyclic transfer of process loop data between devices on the fieldbus. Scheduled transfers use publisher/subscriber type of reporting for data transfer. The Link Active Scheduler maintains a list of transmit times for all publishers in all devices that need to be cyclically transmitted. When it is time for a device to publish data, the LAS issues a Compel Data (CD) message to the device. Upon receipt of the CD, the device broadcasts or publishes the data to all devices on the fieldbus. Any device that is configured to receive the data is called a subscriber.

B Chapter 3 FOUNDATION Fieldbus Technology and October 2007 3.4.4 Unscheduled Transfers Figure 3-4 diagrams an unscheduled transfer. Unscheduled transfers are used for things like user-initiated changes, including set point changes, mode changes, tuning changes, and upload/download. Unscheduled transfers use either report distribution or client/server type of reporting for transferring data. All of the devices on the fieldbus are given a chance to send unscheduled messages between transmissions of scheduled data. The LAS grants permission to a device to use the fieldbus by issuing a pass token (PT) message to the device. When the device receives the PT, it is allowed to send messages until it has finished or until the maximum token hold time has expired, whichever is the shorter time. The message may be sent to a single destination or to multiple destinations.

26 Reference Manual 308017EN, Edition 1/Rev. B Rosemount Tank Radar REX October 2007 Chapter 3 FOUNDATION Fieldbus Technology and 3.4.5 Function Block Scheduling Figure 3-5 shows an example of a link schedule. A single iteration of the link-wide schedule is called the macrocycle. When the system is configured and the function blocks are linked, a master link-wide schedule is created for the LAS. Each device maintains its portion of the link-wide schedule, known as the Function Block Schedule. The Function Block Schedule indicates when the function blocks for the device are to be executed. The scheduled execution time for each function block is represented as an offset from the beginning of the macrocycle start time. Macrocycle Start Time Sequence Offset from Repeats macrocycle start time = 0 for AI Execution Device 1 Offset from macrocycle start AI time = 20 for AI Communication Scheduled Communication Unscheduled AI Communication FF_FUNCTIONBLOCKSCHEDULING Offset from macrocycle start time = 30 for PID Execution Device 2 PID AO PID AO Offset from macrocycle start time = 50 for AO Execution Macrocycle Figure 3-5. Example Link Schedule Showing scheduled and Unsched- uled Communication To support synchronization of schedules, periodically Link Scheduling (LS) time is distributed. The beginning of the macrocycle represents a common starting time for all Function Block schedules on a link and for the LAS link-wide schedule. This permits function block executions and their corresponding data transfers to be synchronized in time. 3-9

Function Block Diagram for the TankRadar REX 3900 Radar Gauge with FOUNDATION fieldbus. It is highly recommended that you limit the number of periodic writes to all static or non-volatile parameters such as HI_HI_LIM, LOW_CUT, SP, TRACK_IN_D, OUT, IO_OPTS, BIAS, STATUS_OPTS, SP_HI_LIM, and so on. Static parameter writes increment the static revision counter, ST_REV, and are written to the device's non-volatile memory. Fieldbus devices have a non-volatile memory write limit. If a static or non-volatile parameter is configured to be written periodically, the device can stop its normal operation after it reaches its limit or fail to accept new values. 5.2 Overview Each FOUNDATION fieldbus configuration tool or host device has a different way of displaying and performing configurations. Some will use Device Descriptions (DD) and DD Methods to make configuration and displaying of data consistent across host platforms. Since there is no requirement that a configuration tool or host support these features, this section will describe how to reconfigure the device manually. Appendix H Operation with Delta V shows the Delta V implementation of these common functions. 5-1

35 Reference Manual Rosemount Tank Radar REX 308017EN, Edition 1/Rev. B Chapter 5 Configuration October 2007 This section covers basic operation, software functionality, and basic configuration procedures for the TankRadar REX 3900 Radar Gauge with FOUNDATION fieldbus (Device Revision 1). For detailed information about FOUNDATION fieldbus technology and the function blocks used in the TankRadar REX 3900 Radar Gauge, refer to the FOUNDATION fieldbus Block manual (Ref. no. 00809-0100-4783). 5.3 Assigning Device Tag and Node Address The TankRadar REX 3900 is shipped with a blank tag and a temporary address (unless specifically ordered with both) to allow a host to automatically assign an address and a tag. If the tag or address need to be changed, use the features of the configuration tool. The tools basically do the following: 1 Change the address to a temporary address (248-251). 2 Change tag to new value. 3 Change address to new address. When the device is at a temporary address, only the tag and address can be changed or written to. The resource, transducer, and function blocks are all disabled. 5.4 Configure Gauge The wizard is used to do a standard configuration of the device. For further information refer to the Rosemount TankMaster Winsetup Users Guide (Ref. no. 303027E) and Appendix C Register Transducer Block. All settings that are made from this method can also be made manually from the DD information, through the parameters listed below. The following are configured by stepping through the Configure Gauge Wizard: 1 Choice of Antenna Type (ANTENNA_TYPE). 2 Based on antenna type choice, the different antenna related con- figuration parameters will be available for configuration. See Table 5-1 for Tank Connection Length (ANTENNA_TCL), and Antenna Pipe Diameter (ANTENNA_PIPE_DIAMETER). 5-2

B Rosemount Tank Radar REX October 2007 Chapter 5 Configuration 5.9 Configuration using the TRL/2 port When using a TankRadar REX 3900 with FOUNDATION fieldbus the configuration of the gauge is done via DeltaV or other Fieldbus Host. With the help of Device descriptors these hosts are able to present, read, and write necessary information and data within the gauge and assist the user to a successful configuration of the gauge. In some cases, there could be a need for a more advanced service access to the gauge. This is done by using the TankMaster and accessing the data from the TRL/2 Bus Port, which is always readily available. Below are instructions of how to connect this port and how to use it. 5.9.1 Electrical Connection The Field Bus Modem is delivered, as standard, with a 3 m long cable for the RS-232C connection to the PC. The TRL/2 bus connection is made with a twisted pair of wires. The Field Bus Modem must not be used in a hazardous zone as it is not explosion protected. The Field Bus Modem is powered from an AC/DC converter (6-12 V, 150 mA) supplied by Emerson Process Management / Rosemount Tank Gauging. In some rare cases the Field Bus Modem can be powered from the RS-232C port of the PC. Connection to Power supply PC (RS232) DC 6-20 V, 10 FF_TRL2BUS Connection to a TRL/2 bus: 1. Shield 2.

Operation and Maintenance 6.1 Overview This section contains information on operation and maintenance procedures. Methods and Manual Operation Each FOUNDATION fieldbus host or configuration tool has different ways of displaying and performing operations. Some hosts will use Device Descriptions (DD) and DD Methods to complete device configuration and will display data consistently across platforms. The DD can be found on www.fieldbus.org. There is no requirement that a host or configuration tool support these features. The information in this section will describe how to use methods in a general fashion. In addition, if your host or configuration tool does not support methods this section will cover manually configuring the parameters involved with each method operation. For more detailed information on the use of methods, see your host or configuration tool manual. 6.2 Safety Messages Procedures and instructions in this section may require special precautions to ensure the safety of the personnel performing the operations. Information that raises potential safety issues is indicated by a warning symbol ( ). Refer to the following safety messages before performing an operation preceded by this symbol. 6.2.1 Configure Gauge Refer to Configure Gauge on page 5-2 for further information regarding the configuration of the Radar Gauge. 6-1

If your host does not support methods ENV_DEVICE_MODE it needs to be manually configured.The following options are available: FOUNDATION fieldbus: Set the device in normal fieldbus communication mode. Restart gauge: Restarts the device, not the fieldbus card. Set to factory default: Sets all configured data to factory settings. 6.2.3 Calibration Distance Configuration See Configure Gauge on page 6-1 for further information. 6.2.4 Master Reset Method (Resource Block) To perform a master reset, run the Master Reset Method. If your system does not support methods, manually configure the Resource Block parameters listed below. Set the RESTART = Run, Resource, Defaults, or Processor Run = nominal state when not restarting (default) Resource = not used by device Defaults = sets parameters to FOUNDATION fieldbus default values Processor = does a warm start of the fieldbus card and the gauge 6.2.5 Write Protection (Resource Block) Inputs to the security and write lock functions include the hardware security jumper, the hardware and software write lock bits of the FEATURE_SEL parameter, the WRITE_LOCK parameter, and the DEFINE_WRITE_LOCK parameter. The WRITE_LOCK parameter limits access to modify parameters within the block except to clear the WRITE_LOCK parameter. During this time, the block will function normally updating inputs and outputs and executing algorithms. When the WRITE_LOCK condition is cleared, a WRITE_ALM alert is generated with a priority that corresponds to the WRITE_PRI parameter. The FEATURE_SEL parameter enables the user to select a hardware or software write lock or no write lock capability. To enable the hardware security function, enable the HW_SEL bit in the FEATURE_SEL parameter. When this bit has been enabled the WRITE_LOCK 6-2

50 Reference Manual 308017EN, Edition 1/Rev. B Rosemount Tank Radar REX October 2007 Chapter 6 Operation and Maintenance parameter becomes read only and will reflect the state of the hardware jumper. In order to enable the software write lock, the SW_SEL bit must be set in the FEATURE_SEL parameter. Once this bit is set, the WRITE_LOCK parameter may be set to LOCKED or NOT LOCKED. Once the WRITE_LOCK parameter is set to LOCKED by either the software or the hardware lock, all user requested writes as determined by the DEFINE_WRITE_LOCK parameter shall be rejected. The DEFINE_WRITE_LOCK parameter allows the user to configure whether the write lock functions (both software and hardware) will control writing to all blocks, or only to the resource and transducer blocks. Internally updated data such as process variables and error logs will not be restricted by the security jumper. The following table displays all possible configurations of the WRITE_LOCK parameter. FEATURE_SELHW_ FEATURE_SELSW_ SECURITY WRITE_ WRITE_ SEL bit SEL bit JUMPER LOCK LOCK Read/Write 0 (off) 0 (off) NA 1 (unlocked) Read only 0 (off) 1 (on) NA 1 (unlocked) Read/Write 0 (off) 1 (on) NA 2 (locked) Read/Write 1 (on) 0 (off)a 0 (unlocked) 1 (unlocked) Read only 1 (on) 0 (off) 1 (locked) 2 (locked) Read only a. The hardware and software write lock select bits are mutually exclusive and the hardware select has the highest priority. When the HW_SEL bit if set to 1 (on), the SW_SEL bit is auto- matically set to 0 (off) and is read only. Table 6-1. WRITE_LOCK parameters 6-3

B Chapter 6 Operation and Maintenance October 2007 6.2.6 Simulation For testing purposes, it is possible to manually drive the output of the Analog Input Block to a desired value. 1 Power up the device. If the SIMULATE jumper is in the OFF position, move it to the ON position. If the SIMULATE jumper is already in the ON position, you must still remove the jumper and place it back in the ON position. Note! As a safety measure, the jumper must be reset every time power is interrupted to the device in order to enable SIMULATE. This prevents a device that is tested on the bench using SIMULATE from getting installed in the process with SIMULATE still active. 2 To change only the OUT_VALUE and not the OUT_STATUS of the AI Block, place the TARGET MODE of the block to MANUAL. Then, change the OUT_VALUE to the desired value. 3 To change both the OUT_VALUE and OUT_STATUS of the AI Block, set the TARGET MODE to AUTO. Set SIMULATE_ENABLE_DISABLE to ACTIVE. Enter the desired SIMULATE_VALUE to change the OUT_VALUE and SIMULATE_STATUS_QUALITY to change the OUT_STATUS. If errors occur when performing the above steps, be sure that the SIMULATE jumper has been reset after powering up the device. 6.2.7 Block Instantiation The Rosemount TankRadar REX 3900 supports the use of Function Block Instantiation. When a device supports block instantiation, the user can define the number of blocks and block types to match specific application needs. The number of blocks that can be instantiated is only limited by the amount of memory within the device and the block types that are supported by the device. Instantiation does not apply to standard device blocks like the Resource, Level Transducer, and Register Transducer Block. Block instantiation is done by the host control system or configuration tool, but not all hosts are required to implement this functionality. Please refer to your specific host or configuration tool manual for more information. Rosemount TankRadar devices are pre-instantiated with function blocks at the factory, the default configuration for the Rosemount TankRadar REX 3900 is listed below. 11 Analog Input Blocks 2 Discrete Input Blocks 6-4

This section contains Rosemount TankRadar REX FOUNDATION fieldbus troubleshooting information only. For troubleshooting information using TankRadar REX TRL/2 bus, see the Rosemount TankRadar REX Service Manual (Ref. no. 308012E). Follow the procedures described here to verify that gauge hardware and process connections are in good working order. Always deal with the most likely checkpoints first. 7.2 Safety Messages Procedures and instructions in this section may require special precautions to ensure the safety of the personnel performing the operations. Information that raises potential safety issues is indicated by a warning symbol ( ). Refer to the following safety messages before performing an operation preceded by this symbol. Explosions can result in death or serious injury. Do not remove the gauge covers in explosive environments when the circuit is live. Gauge covers must be fully engaged to meet explosion proof requirements. Before connecting a communicator in an explosive atmosphere, make sure that the instruments in the loop are installed according to intrinsically safe or nonincendive field wiring practices. Static electricity can damage sensitive components. Observe safe handling precautions for static-sensitive components. 7-1

B Rosemount Tank Radar REX October 2007 Appendix C Register Transducer Block Appendix C Register Transducer Block Overview The Register Transducer Block allows access to Database registers and Input registers of the Rosemount TankRadar REX gauges. This makes it possible to read a selected set of register directly by accessing the memory location. The Register Transducer Block is only available with advanced service. Since this Register Transducer Block allows access to most registers in the gauge, which includes the registers set by the Methods and Configuration screens, in the Level Transducer Block (see Appendix A Specifications) it should be handled with care and ONLY to be changed by trained and certified service personnel, or as guided by Emerson Process Management / Rosemount Tank Gauging support personnel.

82 Reference Manual 308017EN, Edition 1/Rev. B Rosemount Tank Radar REX October 2007 Appendix E Analog-Input Block Appendix E Analog-Input Block Overview The Analog Input (AI) function block processes field device measurements and makes them available to other function blocks. The output value from the AI block is in engineering units and contains a status indicating the quality of the measurement. The measuring device may have several measurements or derived values available in different channels. Use the channel number to define the variable that the AI block processes. OUT_D AI OUT FF_AIBLOCK OUT=The block output value and status OUT_D=Discrete output that signals a selected alarm condition Figure E-1. Analog-Input Block The AI block supports alarming, signal scaling, signal filtering, signal status calculation, mode control, and simulation. In Automatic mode, the blocks output parameter (OUT) reflects the process variable (PV) value and status. In Manual mode, OUT may be set manually. The Manual mode is reflected on the output status. A discrete output (OUT_D) is provided to indicate whether a selected alarm condition is active. Alarm detection is based on the OUT value and user specified alarm limits. Figure E-2 illustrates the internal components of the AI function block, and Table E-1 lists the AI block parameters and their units of measure, descriptions, and index numbers.

Definitions of Analog Input Function Block System Parameters Simulation To support testing, you can either change the mode of the block to manual and adjust the output value, or you can enable simulation through the configuration tool and manually enter a value for the measurement value and its status. In both cases, you must first set the ENABLE jumper on the field device. Note! All fieldbus instruments have a simulation jumper. As a safety measure, the jumper has to be reset every time there is a power interruption. This measure is to prevent devices that went through simulation in the staging process from being installed with simulation enabled. With simulation enabled, the actual measurement value has no impact on the OUT value or the status. E-4

87 Reference Manual Rosemount Tank Radar REX 308017EN, Edition 1/Rev. B Appendix E Analog-Input Block October 2007 Signal Conversion You can set the signal conversion type with the Linearization Type (L_TYPE) parameter. You can view the converted signal (in percent of XD_SCALE) through the FIELD_VAL parameter. ( Channel Value EU*@0% )- FIELD_VAL = 100 ------------------------------------------------------------------------------------- ( EU*@100% EU*@0% ) * XD_SCALE values You can choose from direct or indirect signal conversion with the L_TYPE parameter. Direct Direct signal conversion allows the signal to pass through the accessed channel input value (or the simulated value when simulation is enabled). PV = Channel Value Indirect Indirect signal conversion converts the signal linearly to the accessed channel input value (or the simulated value when simulation is enabled) from its specified range (XD_SCALE) to the range and units of the PV and OUT parameters (OUT_SCALE). FIELD_VAL PV = -------------------------------- ( EU**@100% EU**@0% ) + EU**@0% 100 ** OUT_SCALE values Indirect Square Root Indirect Square Root signal conversion takes the square root of the value computed with the indirect signal conversion and scales it to the range and units of the PV and OUT parameters.. PV = FIELD_VAL -------------------------------- ( EU**@100% EU**@0% ) + EU**@0% 100 ** OUT_SCALE values When the converted input value is below the limit specified by the LOW_CUT parameter, and the Low Cutoff I/O option (IO_OPTS) is enabled (True), a value of zero is used for the converted value (PV). This option is useful to eliminate false readings when the differential pressure measurement is close to zero, and it may also be useful with zero-based measurement devices such as flowmeters. Note! Low Cutoff is the only I/O option supported by the AI block. You can set the I/O option in Manual or Out of Service mode only. E-6

Condition Condition Name and Description Number 0 Other 1 Block Configuration Error: the selected channel carries a measure- ment that is incompatible with the engineering units selected in XD_SCALE, the L_TYPE parameter is not configured, or CHANNEL = zero. 2 Link Configuration Error 3 Simulate Active: Simulation is enabled and the block is using a sim- ulated value in its execution. 4 Local Override 5 Device Fault State Set 6 Device Needs Maintenance Soon 7 Input Failure/Process Variable has Bad Status: The hardware is bad, or a bad status is being simulated. 8 Output Failure: The output is bad based primarily upon a bad input. 9 Memory Failure 10 Lost Static Data 11 Lost NV Data 12 Readback Check Failed 13 Device Needs Maintenance Now 14 Power Up 15 Out of Service: The actual mode is out of service. Table E-2. BLOCK_ERR Conditions Modes The AI Function Block supports three modes of operation as defined by the MODE_BLK parameter: Manual (Man) The block output (OUT) may be set manually Automatic (Auto) OUT reflects the analog input measurement or the simulated value when simulation is enabled. Out of Service (O/S) The block is not processed. FIELD_VAL and PV are not updated and the OUT status is set to Bad: Out of Ser- vice. The BLOCK_ERR parameter shows Out of Service. In this mode, you can make changes to all configurable parameters. The target mode of a block may be restricted to one or more of the supported modes. E-7

89 Reference Manual Rosemount Tank Radar REX 308017EN, Edition 1/Rev. B Appendix E Analog-Input Block October 2007 Alarm Detection A block alarm will be generated whenever the BLOCK_ERR has an error bit set. The types of block error for the AI block are defined above. Process Alarm detection is based on the OUT value. You can configure the alarm limits of the following standard alarms: High (HI_LIM) High high (HI_HI_LIM) Low (LO_LIM) Low low (LO_LO_LIM) In order to avoid alarm chattering when the variable is oscillating around the alarm limit, an alarm hysteresis in percent of the PV span can be set using the ALARM_HYS parameter. The priority of each alarm is set in the following parameters: HI_PRI HI_HI_PRI LO_PRI LO_LO_PRI Alarms are grouped into five levels of priority: Priority Priority Description Number 0 The priority of an alarm condition changes to 0 after the condition that caused the alarm is corrected. 1 An alarm condition with a priority of 1 is recognized by the system, but is not reported to the operator. 2 An alarm condition with a priority of 2 is reported to the operator, but does not require operator attention (such as diagnostics and system alerts). 3-7 Alarm conditions of priority 3 to 7 are advisory alarms of increasing priority. 8-15 Alarm conditions of priority 8 to 15 are critical alarms of increasing pri- ority.

B Rosemount Tank Radar REX October 2007 Appendix E Analog-Input Block Status Handling Normally, the status of the PV reflects the status of the measurement value, the operating condition of the I/O card, and any active alarm condition. In Auto mode, OUT reflects the value and status quality of the PV. In Man mode, the OUT status constant limit is set to indicate that the value is a constant and the OUT status is Good. The Uncertain - EU range violation status is always set, and the PV status is set high- or low-limited if the sensor limits for conversion are exceeded. In the STATUS_OPTS parameter, you can select from the following options to control the status handling: BAD if Limited sets the OUT status quality to Bad when the value is higher or lower than the sensor limits. Uncertain if Limited sets the OUT status quality to Uncertain when the value is higher or lower than the sensor limits. Uncertain if in Manual mode The status of the Output is set to Uncertain when the mode is set to Manual. Note! The instrument must be in Manual or Out of Service mode to set the status option. The AI block only supports the BAD if Limited option. Unsupported options are not grayed out; they appear on the screen in the same manner as supported options. E-9

91 Reference Manual Rosemount Tank Radar REX 308017EN, Edition 1/Rev. B Appendix E Analog-Input Block October 2007 Advanced Features The AI function block provided with Fisher-Rosemount fieldbus devices provides added capability through the addition of the following parameters: ALARM_TYPE Allows one or more of the process alarm conditions detected by the AI function block to be used in setting its OUT_D parameter. OUT_D Discrete output of the AI function block based on the detection of process alarm condition(s). This parameter may be linked to other function blocks that require a discrete input based on the detected alarm condition. VAR_SCAN Time period in seconds over which the variability index (VAR_INDEX) is computed. VAR_INDEX Process variability index measured as the integral of average absolute error between PV and its mean value over the previous evaluation period. This index is calculated as a percent of OUT span and is updated at the end of the time period defined by VAR_SCAN. E-10

92 Reference Manual 308017EN, Edition 1/Rev. B Rosemount Tank Radar REX October 2007 Appendix E Analog-Input Block Configure the AI Block A minimum of four parameters are required to configure the AI Block. The parameters are described below with example configurations shown at the end of this section. CHANNEL Select the channel that corresponds to the desired sensor measurement. The Rosemount TankRadar REX 3900 measures Level (channel 1), Distance (channel 2), Level Rate (channel 3), Signal Strength (channel 4), Volume (channel 5), and Average Temperature (channel 6). L_TYPE The L_TYPE parameter defines the relationship of the gauge measurement (Level, Distance, Level Rate, Signal Strength, Volume, and Average Temperature) to the desired output of the AI Block. The relationship can be direct or indirect root. Direct Select direct when the desired output will be the same as the gauge measurement (Level, Distance, Level Rate, Signal Strength, Volume, and Average Temperature). Indirect Select indirect when the desired output is a calculated measurement based on the gauge measurement (Level, Distance, Level Rate, Signal Strength, Volume, and Average Temperature). The relationship between the gauge measurement and the calculated measurement will be linear. Indirect Square Root Select indirect square root when the desired output is an inferred measurement based on the gauge measurement and the relationship between the sensor measurement and the inferred measurement is square root (e.g. level).

93 Reference Manual Rosemount Tank Radar REX 308017EN, Edition 1/Rev. B Appendix E Analog-Input Block October 2007 XD_SCALE and OUT_SCALE The XD_SCALE and OUT_SCALE each include three parameters: 0%, 100%, and, engineering units. Set these based on the L_TYPE: L_TYPE is Direct When the desired output is the measured variable, set the XD_SCALE to represent the operating range of the process. Set OUT_SCALE to match XD_SCALE. L_TYPE is Indirect When an inferred measurement is made based on the sensor measurement, set the XD_SCALE to represent the operating range that the sensor will see in the process. Determine the inferred measurement values that correspond to the XD_SCALE 0 and 100% points and set these for the OUT_SCALE. L_TYPE is Indirect Square Root When an inferred measurement is made based on the gauge measurement and the relationship between the inferred measurement and sensor measurement is square root, set the XD_SCALE to represent the operating range that the sensor will see in the process. Determine the inferred measurement values that correspond to the XD_SCALE 0 and 100% points and set these for the OUT_SCALE. Note! To avoid configuration errors, only select Engineering Units for XD_SCALE and OUT_SCALE that are supported by the device.

96 Reference Manual 308017EN, Edition 1/Rev. B Rosemount Tank Radar REX October 2007 Appendix F Discrete Input Block Appendix F Discrete Input Block Overview AIDI OUT_D FF_DIBLOCK OUT_D =The discrete output value and status Figure F-1. DI Block The Discrete Input (DI) function block processes a single discrete input from a field device and makes it available to other function blocks. You can configure inversion and alarm detection on the input value. The Discrete Input function block supports mode control, signal status propagation and simulation. Normally, the block is used in Automatic (Auto) mode so that the process variable (PV_D) is copied to the output (OUT_D). You can change the mode to Manual (MAN) to disconnect the field signal and substitute a manually-entered value for OUT_D. In this case, PV_D continues to show the value that will become OUT_D when the mode is changed to Auto. To support testing, you can enable simulation, which allows the measurement value to be manually through the SIMULATE_D parameter. Figure F-2 illustrates the internal components of th DI function block, and Table F-1 lists the definitions of the system parameters. Parameters Units Description BLOCK_ERR None The summary of activ error conditions associated with the block. The sup- ported block errors in the Discrete Input function block are Simulate active, Input failure/process variable has Bad status, and Out of service. See Sys- tem Support. DISC_LIM None The state of the discrete inpute that cuases an alarm. Any number from 0 to 255 may be. State 255 specifies that no alarm indication is to be shown. FIELD_VAL_D None The value and status of the discrete input from a field device. CHANNEL None Definies the I/O input used for the field measurement. F-1

97 Reference Manual Rosemount Tank Radar REX 308017EN, Edition 1/Rev. B Appendix F Discrete Input Block October 2007 Parameters Units Description IO_OPTS None Allows you to select options for I/O value processing. The supported I/O option for the Discrete Input function block is Invert. See System Support. MODE None The mode record of the block. Contains the actual, target, permitted, and normal mode. see System Support. OUT_D None The discrete output value and status. PV_D None The discrete process variable used in block execution. SIMULATE_D None Enables simulation and allow you to enter an input value and status when SIMULATE_IN_D is not connected. Table F-1. Discrete Input Function Block System Parameters Discrete Signal FIELD_VAL_D Alarm FF_DIBLOCKSCHEMATIC Detection OUT_D Invert PV_D Option SIMULATE_D MODE Figure F-2. Discrete Input Function Block Schematic I/O Selection To select the I/O associated with the discrete measurement, configure the value of the CHANNEL attribute. Simulation To support testing, you can either change the mode of the block to manual and adjust the output value, or you can enable simulation through the configuration tool and manually enter a value for the measurement value and its status. In both cases, you must first set the ENABLE jumper on the field device. Note! All fieldbus instruments have an ENABLE jumper. As a safety measure, the jumper has to be reset every time there is a power interruption. This measure is to prevent devices that went through simulation in the staging process from being installed with simulation enabled. With simulation enabled, the actual measurement value has no impact on the OUT_D value or the status. F-2

98 Reference Manual 308017EN, Edition 1/Rev. B Rosemount Tank Radar REX October 2007 Appendix F Discrete Input Block Field Value Processing You can configure the Invert I/O option (IO_OPTS) to process FIELD_VAL_D. The invert option indicates whether or not the discrete input is logically inverted before it is stored in the process variable (PV_D). The output of the Invert processor is PV_D. This value goes to the mode switch where it becomes OUT_D when the mode is Auto. OUT_D is also tested for an alarm state. You might choose this option when the field contact is normally closed, so an open contact or a broken wire represents the active state of the condition being sensed. Note! INVERT is the only I/O mode that the DI block supports. You can set the I/O option in Manual or Out of Service mode only. Alarm Detection To select the state that initiates an input alarm, and to set discrete alarm substatus in the output, configure the DISC_LIM attribute. You can enter any value between 0 and 255. A value of 255 disables the alarm. Block Errors The following conditions are reported in the BLOCK_ERR attribute: Simulate Active - Simulate_D is enabled and OUT_D does not reflect actual process conditions Input Failure/Process Variable has Bad Status - The hardware is bad, the configured channel is invalid or a Bad status is being simulated Out of Service - The block is not being processed Modes Manual (Man) - The output is disconnected from the field. Automatic (Auto) - The block algorithm determines OUT_D Out of Service - The block is not processed. The output status is set to Bad: Out of Service. The BLOCK_ERR attribute shows Out of Service.

99 Reference Manual Rosemount Tank Radar REX 308017EN, Edition 1/Rev. B Appendix F Discrete Input Block October 2007 Status Handling Under normal conditions, a Good: Non-cascade status is passed through to OUT_D. The block also support Status Action on Failure and Block Error indications. Action on failure In case of hardware failure, FIELD_VAL_D, PV_D and OUT_D change to a Bad status and the BLOCK_ERR attribute displays Bad PV. When SIMULATE_D is enabled, FIELD_VAL_D, PV_D and OUT_D change to a simulation status. When the block is set to Man mode, OUT_D is set to Good: Non-cascade, Constant status. F-4
