Guided Wave Radar Transmitter - FOUNDATION fieldbus™ 1.0 1.1 FOUNDATION Fieldbus™ Overview Description FOUNDATION fieldbus™ is a digital communications system that serially interconnects devices in the field. A Fieldbus system is similar to a Distributed Control System (DCS) with two exceptions: • Although a FOUNDATION fieldbus™ system can use the same physical wiring as an existing 4–20 mA device, Fieldbus devices are not connected point to point, but rather are multidropped and wired in parallel on a single pair of wires (referred to as a segment). • FOUNDATION fieldbus™ is a system that allows the user to distribute control across a network. Fieldbus devices are smart and actually maintain control over the system. 6234 feet (1900 meters) maximum PC Power Conditioner Terminator Terminator Power Supply Control Room Typical Fieldbus Installation Unlike 4–20 mA analog installations in which the two wires carry a single variable (the varying 4–20 mA current), a digital communications scheme such as FOUNDATION fieldbus™ considers the two wires as a network. The network can carry many process variables as well as other information. The Enhanced Eclipse Model 705FF transmitter is a FOUNDATION fieldbus™ registered device that communicates with the H1 FOUNDATION fieldbus™ protocol operating at 31.25 kbits/sec. The H1 physical layer is an approved IEC 61158 standard. An IEC61158 shielded twisted pair wire segment can be as long as 6234 feet (1900 meters) without a repeater. Up to 4 repeaters per segment can be used to extend the distance. The maximum number of devices allowed on a Fieldbus segment is 32 although this depends on the current draw of the devices on any given segment. 4 57-640 Eclipse Guided Wave Radar Transmitter - FOUNDATION fieldbus™ Details regarding cable specifications, grounding, termination, and other network information can be found in IEC 61158 or the wiring installation application guide AG-140 at www.fieldbus.org. 1.2 Benefits The benefits of FOUNDATION fieldbus™ can be found throughout all phases of an installation: 1. Design/Installation: Connecting multiple devices to a single pair of wires means less wire and fewer I/O equipment. Initial Engineering costs are also reduced because the Fieldbus Foundation requires interoperability, defined as “the ability to operate multiple devices in the same system, regardless of manufacturer, without a loss of functionality.” All FOUNDATION fieldbus™ devices must be tested for interoperability by the Fieldbus Foundation. Magnetrol Enhanced Model 705 3X FF device registration information can be found at www.fieldbus.org. 2. Operation: With control now taking place within the devices in the field, better loop performance and control are the result. A FOUNDATION fieldbus™ system allows for multiple variables to be brought back from each device to the control room for additional trending and reporting. 3. Maintenance: The self-diagnostics residing in the smart field devices minimizes the need to send maintenance personnel to the field. 1.3 Device Configuration The function of a FOUNDATION fieldbus™ device is determined by the arrangement of a system of blocks defined by the Fieldbus Foundation. The types of blocks used in a typical User Application are described as follows: Resource Block describes the characteristics of the FOUNDATION fieldbus™ device such as the device name, manufacturer, and serial number. Function Blocks are built into the FOUNDATION fieldbus™ devices as needed to provide the desired control system behavior. The input and output parameters of function blocks can be linked over the Fieldbus. There can be numerous function blocks in a single User Application. Transducer Blocks contain information such as calibration parameters and sensor type. They are used to connect the sensor to the input function blocks. 57-640 Eclipse Guided Wave Radar Transmitter - FOUNDATION fieldbus™ 5 Device Descriptions An important requirement of Fieldbus devices is the interoperability concept mentioned earlier. Device Description (DD) technology is used to achieve this interoperability. The DD provides extended descriptions for each object and provides pertinent information needed by the host system. DDs are similar to the drivers that your personal computer (PC) uses to operate peripheral devices connected to it. Any Fieldbus host system can operate with a device if it has the proper DD and Common File Format (CFF) for that device. The most recent DD and CFF files can be found on the FOUNDATION fieldbus™ web site at www.fieldbus.org. NOTE: Please consult your host system vendor for any host-specific files that may be needed. 1.3.1 FOUNDATION fieldbus™ Revision Table Model 705 3.x FOUNDATION fieldbus™ FOUNDATION fieldbus™ Version Release Date Dev V1 DD V1 Dev V2 DD V1 June 2005 June 2008 Compatible with 705 Software Version 3.0A through Version 3.0K Version 3.1A and later 1.4 Intrinsic Safety The H1 physical layer supports Intrinsic Safety (IS) applications with bus-powered devices. To accomplish this, an IS barrier or galvanic isolator is placed between the power supply in the safe area and the device in the hazardous area. H1 also supports the Fieldbus Intrinsically Safe Concept (FISCO) model which allows more field devices in a network. The FISCO model considers the capacitance and inductance of the wiring to be distributed along its entire length. Therefore, the stored energy during a fault will be less and more devices are permitted on a pair of wires. Instead of the conservative entity model, which only allows about 90 mA of current, the FISCO model allows a maximum of 110 mA for Class II C installations and 240 mA for Class II B installations. FISCO certifying agencies have limited the maximum segment length to 1000 meters because the FISCO model does not rely on standardized ignition curves. The Enhanced Eclipse Model 705 is available with entity IS, FISCO IS, FNICO non-incendive, or explosion proof approvals. 6 57-640 Eclipse Guided Wave Radar Transmitter - FOUNDATION fieldbus™ 1.5 Link Active Scheduler (LAS) The default operating class of the Enhanced Eclipse Model 705 with FOUNDATION fieldbus™ is a basic device. However, it is capable of being a Link Active Scheduler (LAS). The LAS controls all communication on a FOUNDATION fieldbus™ segment. It maintains the “Live List” of all devices on a segment, coordinates both the cyclic and acyclic timing and, at any given time, controls which device publishes data via Compel data (CD) and Pass Token (PT). The primary LAS is usually maintained in the host system, but in the event of a failure, all associated control can be transferred to a backup LAS in a field device such as the Enhanced Eclipse Model 705. The operating class can be changed from basic to LAS using a FOUNDATION fieldbus™ configuration tool. NOTE: The Enhanced Eclipse Model 705 is shipped from the factory with Device Class set to Basic. 2.0 QuickStart Installation The QuickStart Installation procedures provide the key steps for mounting, wiring, and configuring the Eclipse level transmitter. These procedures are intended for experienced installers of electronic level measurement instruments. See Complete Installation, Section 3.0, for detailed installation instructions.

Refer to Bulletins 57-101 and 57-600 for more detailed information on the Eclipse product family. The Enhanced Eclipse Model 705FF is a Guided Wave Radar (GWR) level transmitter with seven FOUNDATION fieldbus™ Function Blocks (one Resource Block, one Transducer Block, four Analog Input Blocks, and one PID Block). The idea of Function Blocks, which a user can customize for a particular application, is a key concept of Fieldbus topology. Function Blocks consist of an algorithm, inputs and outputs, and a user-defined name. The TRANSDUCER block output is available to the network through the ANALOG INPUT blocks. • The ANALOG INPUT blocks (AI) take the TRANSDUCER block level or volume values and makes them available as an analog value to other function blocks. The AI blocks have scaling conversion, filtering, and alarm functions. 4.1.1 Universal Fieldbus Block Parameters The following are general descriptions of the parameters common to all blocks. Additional information for a given parameter is described later in that specific block section. ST_REV (static data revision): a read only parameter that gives the revision level of the static data associated with the block. This parameter will be incremented each time a static parameter attribute value is written and is a vehicle for tracking changes in static parameter attributes. TAG_DESC (tag descriptor): a user assigned parameter that describes the intended application of any given block. STRATEGY: a user assigned parameter that identifies groupings of blocks associated with a given network connection or control scheme. ALERT_KEY: a user assigned parameter which may be used in sorting alarms or events generated by a block. MODE_BLK: a structured parameter composed of the actual mode, the target mode, the permitted mode(s), and the normal mode of operation of a block. • The actual mode is set by the block during its execution to reflect the mode used during execution. • The target mode may be set and monitored through the mode parameter. 20 57-640 Eclipse Guided Wave Radar Transmitter - FOUNDATION fieldbus™ • The permitted modes are listed for each block. • The block must be in an automatic mode for normal operation. NOTE: The MODE_BLK target parameter must be OOS (out of service) to change configuration and calibration parameters in that function block (when in OOS, the normal algorithm is no longer executed and any outstanding alarms are cleared). All blocks must be in an operating mode for the device to operate. This requires the Resource Block to be in “AUTO” and the Transducer Block to be in “AUTO” before the Function Blocks can be placed in a mode other than OOS (out of service). BLOCK_ERR: a parameter that reflects the error status of hardware or software components associated with, and directly affecting, the correct operation of a block. NOTE: A BLOCK_ERR of “Simulation Active” in the Resource Block does not mean simulation is active—it merely indicates that the simulation (hardware) enabling jumper is present. 4.2 Resource Block The RESOURCE block contains data specific to the Enhanced Model 705 transmitter, along with some information about the firmware. NOTE: The Resource Block has no control function. MODE_BLK: Must be in AUTO in order for the remaining blocks in the transmitter to operate. NOTE: A Resource Block in “out of service” will stop all function block execution in the transmitter. RS_STATE (Resource State): identifies the state of the RESOURCE block state machine. Under normal operating conditions, it should be “On-Line.” DD_RESOURCE: a string identifying the tag of the resource that contains the Device Description for this device. MANUFAC_ID: contains Magnetrol International’s FOUNDATION fieldbus™ manufacturer’s ID number, which is 0x000156. DEV_TYPE: the model number of the Enhanced Eclipse Model 705 transmitter (0x0001). It is used by interface devices to locate the Device Descriptor (DD) file for this product. DEV_REV: contains the firmware revision of the Enhanced Eclipse Model 705 transmitter. It is used by interface devices to correctly select the associated DD. 57-640 Eclipse Guided Wave Radar Transmitter - FOUNDATION fieldbus™ 21 DD_REV: contains the revision of the DD associated with the version of firmware in the Enhanced Eclipse Model 705 transmitter. It is used by interface devices to correctly select the associated DD. RESTART: Default and Processor selections are available. Default will reset the Model 705 to the established block configuration. NOTE: As RESTART DEFAULT will set most configuration parameters to their default values. Devices need to be reconfigured following activation of this function FEATURES: a list of the features available in the transmitter. The Model 705 features include Reports, and Soft Write Lock. FEATURES_SEL: allows the user to turn Features on or off. CYCLE_TYPE: identifies the block execution methods that are available. CYCLE_SEL: allows the user to select the block execution method. MIN_CYCLE_T: the time duration of the shortest cycle interval. It puts a lower limit on the scheduling of the resource. NV_CYCLE_T: the minimum time interval between copies of non-volatile (NV) parameters to NV memory. NV memory is only updated if there has been a significant change in the dynamic value and the last value saved will be available for the restart procedure. A value of “0” means it will never be automatically copied. Entries made by human interface devices to NV parameters are copied to non-volatile memory at the time of entry. NOTE: After completing a large copy, allow several seconds before removing power from the Eclipse Model 705 transmitter to ensure that all data has been saved. FREE_SPACE: shows the amount of available memory for further configuration. The value is zero percent in a preconfigured device. FREE_TIME: the amount of the block processing time that is free to process additional blocks. SHED_RCAS: the time duration at which to give up computer writes to function block RCas locations. Shed from RCas will never happen when SHED_RCAS = 0. SHED_ROUT: the time duration at which to give up computer writes to function block ROut locations. Shed from ROut will never happen when SHED_ROUT = 0. 22 57-640 Eclipse Guided Wave Radar Transmitter - FOUNDATION fieldbus™ FAULT_STATE, SET_FSTATE, CLR_FSTATE: these only apply to output function blocks. (The Model 705 has no output function blocks). MAX_NOTIFY: the maximum number of alert reports that the transmitter can send without getting a confirmation. The user can set the number low, to control alert flooding, by adjusting the LIM_NOTIFY parameter value. LIM_NOTIFY: the maximum numbers of unconfirmed alert notify messages allowed. No alerts are reported if set to zero. CONFIRM_TIME: the time that the transmitter will wait for confirmation of receipt of a report before trying again. Retry will not occur if CONFIRM_TIME = 0. WRITE_LOCK: When set to LOCKED, will prevent any external change to the static or non-volatile data base in the Function Block Application of the transmitter. Block connections and calculation results will proceed normally, but the configuration will be locked. UPDATE_EVT (Update Event): is an alert generated by a write to the static data in the block. BLOCK_ALM (Block Alarm): is used for configuration, hardware, connection, or system problems in the block. The cause of any specific alert is entered in the subcode field. The first alert to become active will set the Active status in the Status attribute. As soon as the Unreported status is cleared by the alert reporting task, another block alert may be reported without clearing the Active status, if the subcode has changed. ALARM_SUM (Alarm Summary): contains the current alert status, the unacknowledged states, the unreported states, and the disabled states of the alarms associated with the block. ACK_OPTION (Acknowledge Option): selects whether alarms associated with the block will be automatically acknowledged. WRITE_PRI (Write Priority): the priority of the alarm generated by clearing the write lock. WRITE ALM (Write Alarm): the alert generated if the write lock parameter is cleared. ITK_VER (ITK Version): contains the version of the Interoperability Test Kit (ITK) used by the Fieldbus Foundation during their interoperability testing. 57-640 Eclipse Guided Wave Radar Transmitter - FOUNDATION fieldbus™ 23 4.3 Transducer Block The TRANSDUCER block is a custom block containing parameters that support the Enhanced Eclipse Model 705 level transmitter. It contains the GWR probe configuration, diagnostics, and calibration data, and outputs level with status information. The TRANSDUCER block parameters are grouped in a useful configuration. There are both read-only parameters and read-write parameters within the TRANSDUCER block. • The read-only parameters report the block status and operation modes. • The read-write parameters affect the function block basic operation, level transmitter operation, and calibration. The Transducer Block will automatically be changed to “Out of Service” when the local interface (keypad) is used to change a parameter online. The Transducer Block must be placed back in service from the Host system. 4.3.1 Transducer Block Parameters The first six parameters in the TRANSDUCER block are the universal parameters discussed in section 4.1.1. The universal parameters are followed by these additional required parameters: UPDATE_EVT (Update Event): an alert generated by a write to the static data in the TRANSDUCER block. Another important parameter found later in the TRANSDUCER block list is DEVICE_STATUS, which displays the status of the device. If more than one message exists, then the messages are displayed in priority order. If DEVICE_STATUS indicates a problem, refer to Section 7.1, Troubleshooting (those parameters which are shaded are password-protected). For a complete list of Transducer Block Parameters, refer to table in the Appendix. 4.3.2 Password Parameters To change a parameter at the local user interface, a value matching the user password must be entered (Default=1). If the user password is entered, the instrument is in the user mode. After 5 minutes with no keypad activity, the entered password expires. Factory password is for use by trained factory personnel only. From the Host system network, the instrument always behaves as if it is in the user mode by default. In other words, it is not necessary to enter the user password in order to write parameters from the Host system. 24 57-640 Eclipse Guided Wave Radar Transmitter - FOUNDATION fieldbus™ 4.3.3 Eclipse Model 705 Configuration Parameters This set of parameters within the Transducer Block is important and required to configure every Eclipse Model 705 transmitter. PROBE_MODEL: Select the choice that corresponds to the first four digits of the model number of the probe. An “x” in the selection means that character is variable (the probe model number is shown on the nameplates attached to both the transmitter and probe). For example, 7xA-x should be chosen for probe models beginning with 7EA or 7MA. Probe Mount 100% Set Point Probe Model Dielectric of Medium 0% Set Point PROBE_MOUNT: Select the type of mounting on the probe. The choices are NPT, BSP, and Flange. MEASUREMENT_TYPE: Select from LEVEL ONLY, LEVEL AND VOLUME, INTERFACE, or INTERFACE AND VOLUME. PROBE_LENGTH: Enter the exact length of the probe. The probe length is shown as the last three digits of the probe model number printed on the nameplates attached to the transmitter and probe. PROBE_LENGTH is shown in SENSOR_UNITs. LEVEL_OFFSET: Enter the distance from the probe tip to the desired 0% reference in PROBE_UNITs. The acceptable range is from -300 inches to 600 inches. Refer to Section 4.3.4 for additional information. DIELECTRIC_RANGE: Select from 10–100, 3–10, 1.7–3.0, or 1.7–1.4 NOTE: All dielectric ranges are not available with all probes. Probe Length Offset If an unsupported dielectric range is selected, the transmitter will give a negative response and the value displayed will revert to its previous value. THRESHOLD: The threshold can be set as either FIXED or CFD. This parameter should be set to FIXED in those applications measuring total level having a lower dielectric material over a higher dielectric material. (A typical example for FIXED Threshold is a hydrocarbon application having water bottoms.) 57-640 Eclipse Guided Wave Radar Transmitter - FOUNDATION fieldbus™ 25 4.3.4 Offset Description LCD Menu LvlUnits in 100% PrbModel 7xA-x PrbMount NPT 60" The parameter referred to as LEVEL_OFFSET in the Transducer Block is the desired level reading when liquid surface is at the end of the probe. The Eclipse transmitter is shipped from the factory with LEVEL_OFFSET set to 0. With this configuration, all measurements are referenced from the bottom of the probe. See Example 1. Example 1 (LEVEL_OFFSET = 0 as shipped from factory): Application calls for a 72-inch NPT Coaxial probe in water with the bottom of the probe 10 inches above the bottom of the tank. The user wants the 0% point at 24 inches and the 100% point at 60 inches as referenced from the bottom of the probe. In those applications in which it is desired to reference all measurements from the bottom of the vessel, the value of LEVEL_OFFSET should be changed to the distance between the bottom of the probe and the bottom of the vessel as shown in Example 2. Probe Ln 72 in Lvl Ofst 0.0 in Dielctrc 10-100 0% 24" 10" Example 1 LCD Menu LvlUnits in PrbModel 7xA-x PrbMount NPT Probe Ln 72 in Lvl Ofst 10 in 24" 10" 100% Example 2: Application calls for a 72-inch NPT coaxial probe in water with the bottom of the probe 10 inches above the bottom of the tank. The user wants the 0% point at 24 inches and the 100% point at 60 inches as referenced from the bottom of the tank. When the Eclipse transmitter is mounted in a chamber/bridle, it is usually desirable to configure the unit with the 0% point at the lower process connection and the 100% point at the upper process connection. The span is the center-to-center dimension. In this case, a negative LEVEL_OFFSET needs to be entered. In doing so, all measurements are then referenced at a point up on the probe as shown in Example 3. Example 3: Application calls for a 48-inch cage-coaxial flanged probe measuring water in a chamber with the bottom of the probe 6 inches below the lower process connection. The user wants the 0% point to be 0 inches at the bottom process connection and the 100% point to be 30 inches at the top process connection. 60" 0% Dielctrc 10-100 Example 2 LCD Menu LvlUnits in 100% PrbModel 7xR-x PrbMount Flange 30" Probe Ln 48 in 0% 6" Lvl Ofst -6.0 in Dielctrc 10-100 Example 3 26 57-640 Eclipse Guided Wave Radar Transmitter - FOUNDATION fieldbus™ 4.4 User-Calibration Parameters One of the main advantages of the Enhanced Eclipse Model 705 GWR transmitter is that the device does not need to be calibrated in the field. Every Enhanced Eclipse Model 705 transmitter is shipped precisely calibrated from the factory. On the other hand, part of the advantage of FOUNDATION fieldbus™ is to provide the ability to monitor changes and make adjustments to a transmitter. The Fieldbus™ concept allows a user to make calibration adjustments if deemed necessary. NOTE: The original factory calibration settings are restored when a new probe length value is assigned. It is highly recommended that factory calibration be used for optimum performance. Contact the factory for information on how to perform a User Calibration. 4.4.1 Factory Parameters The factory-adjustable calibrated parameters are WINDOW, CONVERSION_FACTOR, and SCALE_OFFSET. WINDOW is used to adjust for the variations in the analog section of the Eclipse TDR measurement engine. CONVERSION_FACTOR and SCALE_OFFSET are the main factory calibration settings. The following parameters are used for either troubleshooting or are parameters adjusted at the factory. They should never be changed in the field. WINDOW: determines the amount of delay between the generation of the transmitted signal pulse and the start of the measurement cycle. FID_TICKS: a measure of the time to the fiducial (reference) pulse. FID_TICKS_SPREAD: provides an indication of the stability of the FID_TICKS measurement. LEVEL_TICKS: a measure of the time to the level of the product being measured. LEVEL_TICKS_SPREAD: provides an indication of the stability of the LEVEL_TICKS measurement. CONVERSION_FACTOR: the slope of the factory-set calibration line. SCALE_OFFSET: the intercept of the calibration line. 57-640 Eclipse Guided Wave Radar Transmitter - FOUNDATION fieldbus™ 27 4.4.2 Firmware Version The last parameter in the TRANSDUCER block gives the firmware version of the transmitter. FIRMWARE_VERSION: displays the version of the firmware. NOTE: The user should compare the DD file and revision number of the device with the HOST system to ensure they are at the same revision level. Refer to the table on page 6. 4.5 Analog Input Block The ANALOG INPUT (AI) block takes the Eclipse Model 705 input data, selected by channel number, and makes it available to other function blocks at its output: Channel Process Value 1 2 3 4 Level Volume Interface Interface Volume 4.5.1 AI Block Parameters 100% XD_SCALE "EU@100%" (in.cm, ft.m) XD_SCALE "EU@0%" (in. cm, ft. m) PV: Either the primary analog value for use in executing the function, or a process value associated with it. OUT: The primary analog value calculated as a result of executing the function block. SIMULATE: Allows the transducer analog input or output to the block to be manually supplied when simulate is enabled. When simulate is disabled, the simulate value and status track the actual value and status XD_SCALE: The high and low scale values, engineering units code, and number of digits to the right of the decimal point used with the value obtained from the transducer for a specified channel. OUT_SCALE: The high and low scale values, engineering units code, and number of digits to the right of the decimal point to be used in displaying the OUT parameter. GRANT_DENY: Options for controlling access of host computers and local control panels to operating, tuning, and alarm parameters of the block. IO_OPTS: Option which the user may select to alter input and output block processing. STATUS_OPTS: Options which the user may select in the block processing of status. Probe Length 0% Offset Default Scaling 28 57-640 Eclipse Guided Wave Radar Transmitter - FOUNDATION fieldbus™ CHANNEL: The number of the logical hardware channel that is connected to this I/O block. This information defines the transducer to be used going to or from the physical world. L_TYPE: Determines if the values passed by the transducer block to the AI block may be used directly (Direct) or if the value is in different units and must be converted linearly (Indirect), or with square root (Ind Sqr Root), using the input range defined for the transducer and the associated output range. LOW_CUT: Limit used in square root processing. PV_FTIME: Time constant of a single exponential filter for the PV, in seconds. FIELD_VAL: Raw value of the field device in % of PV range, with a status reflecting the Transducer condition, before signal characterization (L_TYPE) or filtering (PV_FTIME). UPDATE_EVT: This alert is generated by any change to the static data. BLOCK_ALM: The block alarm is used for all configuration, hardware, connection failure or system problems in the block. ALARM_SUM: The current alert status, unacknowledged states, unreported states, and disabled states of the alarms associated with the function block. ACK_OPTION: Selection of whether alarms associated with the function block will be automatically acknowledged. ALARM_HYS: Amount the PV must return within the alarm limits before the alarm condition clears. Alarm hysteresis expressed as a percent of the span of the PV. HI_HI_PRI: Priority of the high high alarm. HI_HI_LIM: The setting for high high alarm in engineering units. HI_PRI: Priority of the high alarm.

LO_LO_LIM: The setting for low low alarm in engineering units. HI_HI_ALM: The status for high high alarm and its associated time stamp. 57-640 Eclipse Guided Wave Radar Transmitter - FOUNDATION fieldbus™ 29 HI_ALM: Status for high alarm and associated time stamp. LO_ALM: Status for low alarm and associated time stamp. LO_LO_ALM: The status for low low alarm and its associated time stamp. The TRANSDUCER and AI block’s MODE_BLK parameter must be set to AUTO to pass the PV Value through the AI to the network. Transducer scaling, called XD_SCALE, is applied to the PV from the CHANNEL to produce the FIELD_VAL in percent. Valid XD_SCALE engineering units is limited to the five allowable codes of meters (m), centimeters (cm), feet (ft), inches (in), and percent (%) for the Level channels, or gallons, liters, % for the volume channels. 1. 2. 3. 4. The AI blocks can have a BLOCK_ERR when: Channel is not set correctly. XD_SCALE does not have suitable engineering units or has range incompatibility. SIMULATE parameter is active AI block MODE is O/S (out of service). NOTE: This can be caused by the Resource Block being OOS or the AI Block not scheduled for execution. 5. L-TYPE not set or set to Direct with improper OUT_SCALE. The AI block uses the STATUS_OPTS setting and the TRANSDUCER PV LIMIT value to modify the AI PV and OUT QUALITY. Damping Filter is a feature of the AI block. The PV_FTIME parameter is a time constant of a single exponential filter for the PV, in seconds. This parameter can be used to dampen out fluctuation in level due to excessive turbulence. The AI block has multiple ALARM functions that monitor the OUT parameter for out of bound conditions. 4.5.2 Local Display of Analog Input Transducer Block Output The Model 705 3x FOUNDATION fieldbus™ Device Revision 2 transmitter incorporates a feature that allows the device’s Analog Input [AI] block Out values to be displayed on the local LCD. NOTE: There are many reasons that AI block Out values can deviate from the measurement value originating in the Transducer block, and because the keypad and local display will only provide access to Transducer block parameters, there is no way to explore or change the other fieldbus configuration items affecting the AI block output using the keypad and LCD. 30 57-640 Eclipse Guided Wave Radar Transmitter - FOUNDATION fieldbus™ 4.5.2 Local Display of Analog Input Transducer Block Output These screens should only be considered as measured value indicators for configured transmitters. • The screens are not used for commissioning or diagnostic / troubleshooting purposes. • Prior to full fieldbus configuration (transmitter assigned a permanent address, AI block(s) configured and scheduled for execution, etc.), the value displayed will not reflect the transducer measurement. (Pre-configuration values will typically be 0). 4.5.2.1 AI Out Display Screens Analog Input block # AI block channel measurement type The Analog Input Out values will be conditionally displayed as part of the “rotating” home menu screens. The screens will be formatted as shown where # in the title is the number of the AI block (1, 2, 3, or 4) and mmm is one of: “Lvl”, “Vol”, “Ifc”, “IfV”, “---” depending on the value of the associated AI block’s Channel parameter. • For example, “AI1Lvl” would be the most commonly used AI Out screen. • “AI2---” would be displayed when the channel value is 0 [uninitialized] for AI block 2. The Out value will be displayed subject to limitations necessary for a 6-character display [999999 > Value > -99999]. Representative examples are shown below: *AI1Lvl* 99.5 cm *AI3Ifc* 0.0 % *AI1Vol* 999999 L *AI#mmm* ######uu Out Scale units abbreviation Out Value Analog Input Out Display Local AI Display AI1 Out AI2 Out AI3 Out AI4 Out Because the Model 705 transmitter has four Analog Input blocks any or all of which may be used in particular applications, a Transducer block parameter controls which AI block Out values will be displayed. The fieldbus presentation of this parameter will be similar to that shown at left (host system dependent). Any or all (or none) of the AI block Out values can be selected for display on the LCD. None AI1 AI2 AI1+AI2 AI3 AI1+AI3 AI2+AI3 AIs1,2,3 AI4 AI1+AI4 AI2+AI4 AIs1,2,4 AI3+AI4 AIs1,3,4 AIs2,3,4 All AIs The local LCD version of this parameter is shown differently due to the limitations of the LCD: LCD label: “AI Disp ” The default value of the Local AI Display parameter will be such that AI 1 Out is selected. Analog Input Out Values To Be Displayed 57-640 Eclipse Guided Wave Radar Transmitter - FOUNDATION fieldbus™ 31 4.6 PID Block The PID Function Block contains the logic necessary to perform Proportional/Integral/Derivative (PID) control. The block provides filtering, set point limits and rate limits, feedforward support, output limits, error alarms, and mode shedding. Although most other function blocks perform functions specific to the associated device, the PID block may reside in any device on the network.
