With this dual input configuration, instrument costs can be reduced by as much as 50 percent. In addition, the multi-drop capability of F results in additional savings through reduced wiring costs.

OUNDATION fieldbus

FOUNDATION FIELDBUS

TECHNOLOGY OVERVIEW

FOUNDATION fieldbus is an all digital, serial, two-way communication system that interconnects field equipment such as sensors, actuators, and controllers. Fieldbus is a Local Area Network (LAN) for instruments that are used in both process and manufacturing automation, having the built-in capability to distribute the control application across the network. The fieldbus environment is the base level group of digital networks in the hierarchy of plant networks.

The fieldbus retains the desirable features of the 4–20 mA analog system, including standardized physical interface to the wire, bus-powered devices on a single pair of wires, and intrinsic safety options. It also enables the following capabilities:

• Increased capabilities due to full digital communication.

• Reduced wiring and wire terminations due to multiple devices on one pair of wires.

• Increased supplier selection due to interoperability.

• Reduced loading on control room equipment due to the distribution of some control and input/output functions to field devices.

GENERAL CONSIDERATIONS

ELECTRICAL CONSIDERATIONS

Electrical temperature sensors, such as RTDs and thermocouples, produce low-level signals proportional to temperature. The Model 3244MV MultiVariable Temperature Transmitter converts the analog sensor signal to a digital signal that is relatively insensitive to lead length and electrical noise. This signal is then transmitted over the F

OUNDATION fieldbus to the control room using two wires.

Proper electrical installation is necessary to prevent errors due to sensor lead resistance and electrical noise. Shielded, twisted cable produce the best results in electrically noisy environments. Figure 2-1 on page -3 shows a typical F

OUNDATION fieldbus installation.

Power Supply The transmitter requires between 9 and 32 V dc to operate and provide

complete functionality. The dc power supply should provide power with less than 2% ripple.

Power Filter A fieldbus segment requires a power conditioner to isolate the power

supply filter and decouple the segment from other segments attached to the same power supply.

Field Wiring All power to the transmitter is supplied over the signal wiring. Signal

wiring should be a shielded, twisted pair for best results. Do not run unshielded signal wiring in conduit or open trays with power wiring or near heavy electrical equipment.

If the sensor is installed in a high-voltage environment and a fault condition or installation error occurs, the sensor leads and transmitter terminals could carry lethal voltages. Use extreme caution when making contact with the leads and terminals.

NOTE

Do not apply high voltage (e.g. ac line voltage) to the transmitter terminals. Abnormally high voltage can damage the unit. Sensor and transmitter power terminals are rated to 42.4 V dc.

2-2

Installation

Power Connections

Use copper wire of sufficient size to ensure that the voltage across the transmitter power terminals is not below 9 V dc.

To connect power to the transmitter, follow the steps below:

1. Remove the transmitter cover to expose the transmitter terminal block. Do not remove transmitter covers in explosive atmospheres when the circuit is live.

2. Connect the power leads to the terminals marked “+” and “T” as shown in Figure 2-2 on page -4. The power terminals are not polar sensitive, meaning that the electrical polarity of the power leads is not significant when connecting to the power terminals. The use of crimped lugs is recommended when wiring to screw terminals.

3. Tighten the terminal screws to ensure adequate contact. No additional power wiring is needed.

4. Replace the transmitter cover, tightening the cover threads at least one-third turn after the o-ring contacts the housing. Both transmitter covers must be fully engaged to meet explosion-proof requirements.

Ground Terminal

Grounding Transmitters are electrically isolated to 500 V ac rms. If desired, you

can ground the signal wiring at any single point. When using a grounded thermocouple, the grounded junction serves as this point.

NOTE

Do not ground the signal wire at both ends.

Shielded Wire

To avoid grounding the loop, the recommended grounding techniques for shielded wire usually requires a single grounding point for each shielded wire. The following examples illustrate the single grounding point technique:

Example 1

Connect the shield for the signal wiring to the shield for the sensor wiring. Verify that the two shields are tied together and electrically isolated from the transmitter housing. Ground the shield at the power supply end.

3144-0200E01C

2-4

Example 2

Connect the shield for the sensor wiring to the ground terminal, which is located inside the terminal compartment of the transmitter housing. The shield for the signal wiring should be cut and isolated from the transmitter housing and should be grounded only at the power supply end. Never connect the shield for the signal wiring to the ground terminal inside the transmitter housing.

Transmitter Housing

Ground the transmitter housing in accordance with local electrical requirements. An internal ground terminal is standard. If necessary, an optional external ground lug assembly (option code G1) can be ordered. An external ground lug is installed when ordering certain hazardous locations approvals (see Figure 7-5 on page 7-10). External grounding is recommended when using the optional transient protector (option code T1).

Installation

Surges/Transients The transmitter will withstand the electrical transients of energy level

that usually occurs through static discharges or induced switching. However, high-energy transients, such as those induced by lightning strikes, can damage both the transmitter and the sensor. To protect against high-energy transients, install the integral transient protection board (option code T1). The integral transient protection board is available as an ordered option or as an accessory. Refer to “Transient Protection (option code T1)” on page 9-2 for more information.

SWITCHES Security After configuring the transmitter, you may want to protect the

configuration data from unwarranted changes. Each transmitter is equipped with a security switch that can be positioned “ON” to prevent the accidental or deliberate change of configuration data. This switch is located on the front side of the electronics module and is labeled SECURITY (see Figure 2-3 on page -5).

Simulate The simulate switch is used in conjunction with the Analog Input (AI)

function block. This switch is used to simulate temperature measurement and as a lock-out feature for the AI function block. To enable the simulate feature, the switch must transition from “OFF” to “ON” after power is applied to the transmitter. When the LCD meter is installed, the simulate feature is enabled with a jumper (see Figure 2-3 on page 2-5). This feature prevents the transmitter from being left in simulator mode.

SENSOR CONNECTIONS The Model 3244MV is compatible with a number of RTD and

thermocouple sensor types. Figure 2-4 on page 2-6 shows the correct input connections to the sensor terminals on the transmitter. To ensure an adequate sensor connection, anchor the sensor lead wires beneath the flat washer on the terminal screw. Do not remove the transmitter cover in explosive atmospheres when the circuit is live. Both transmitter covers must be fully engaged to meet explosion-proof requirements.

If the sensor is installed in a high voltage environment and a fault condition or installation error occurs, the sensor leads and transmitter terminals could carry lethal voltages. Use extreme caution when making contact with the leads and terminals.

RTD or Ohm Inputs Various RTD configurations, including 2-wire, 3-wire, 4-wire, and

compensation loop designs, are used in industrial applications. When the transmitter is mounted remotely from a 3- or 4-wire RTD, it will operate within specifications, without recalibration, for lead wire resistances of up to 10 ohms per lead (equivalent to 1,000 feet of 20 AWG wire). In this case, the leads between the RTD and transmitter should be shielded. When using only two leads (or a compensation loop lead wire configuration), both RTD leads are in series with the sensor element. Significant errors can occur if the lead lengths exceed one foot of 20 AWG wire.

For direct-mount applications, connect the thermocouple directly to the transmitter. When mounting the transmitter remotely from the sensor, use appropriate thermocouple extension wire. Make connections for millivolt inputs with copper wire. Use shielding for long runs of wire.

NOTE

The use of two grounded thermocouples with the Model 3244MV is not recommended. For applications in which the use of two thermocouples is desired, connect either two ungrounded thermocouples, one grounded and one ungrounded thermocouple, or one dual element thermocouple.

MECHANICAL CONSIDERATIONS

Using an optional mounting bracket (see Figure 2-7 on page 2-10), you can attach the Model 3244MV to:

• directly to a sensor

• apart from the sensor

• to a flat surface

• to a 2-inch diameter pipe

Installing the LCD Meter Transmitters ordered with the LCD meter option (option code M5) are

shipped with the meter installed. If later installation of the LCD meter is desired, a small instrument screwdriver and a LCD meter with the Meter Cover Kit are required (see “Spare Parts List” on page 7-13). The Meter Cover Kit includes:

• LCD meter display

• Meter cover with o-ring in place

• Captive mounting screws (quantity 2)

• 10-pin interconnection header

To install the LCD Meter with Meter Cover Kit refer to Figure 2-5 and Figure 2-7 while following the steps below.

1. Remove the transmitter cover to expose the transmitter electronics. Do not remove the transmitter covers in explosive atmospheres when the circuit is live.

2. Ensure that the transmitter SECURITY switch is set to the “OFF” position.

3. Insert the long pins on the interconnection header into the ten-pin socket located on the face of the electronics module assembly.

4. Orient the LCD meter. The LCD meter can be rotated in 90-degree increments for easy viewing. Position one of the four ten-pin sockets into the back of the meter to accept the interconnection header. Insert the captive mounting screws into the two holes on the meter that coincide with the appropriate holes on the electronics module assembly.

5. Attach the meter to the electronics with the captive mounting screws.

6. Insert the SIMULATE jumper into the three pin socket located on the face of the meter.

7. Thread the meter cover onto the housing. Be sure to tighten the cover threads at least one-third turn after the o-ring contacts the housing. Both transmitter covers must be fully engaged to meet explosion-proof requirements.

8. When power is applied to the transmitter, the LCD meter will need to be configured by setting the DISPLAY_MODE parameter (see Section 5: Resource Block for more details on configuring the LCD meter).

Mounting The transmitter may require supplementary support under

high-vibration conditions, particularly if used with extensive thermowell lagging or long extension fittings. Pipe stand mounting, using one of the optional mounting brackets, is recommended for use in high-vibration applications.

Access Requirements Take into account the need to access the transmitter when choosing an

installation location and position.

Housing Rotation

You may rotate the electronics housing up to 90 degrees in either direction to improve field access to the two compartments.

Terminal Block Side of the Housing

Mount the transmitter so the terminal block side is accessible. Allow adequate clearance for cover removal. Make wire connections through the conduit openings on the bottom of the housing.

Electronics Side of the Housing

Mount the transmitter so the electronics-side is accessible. Provide adequate clearance for cover removal and leave additional room if an LCD meter is installed.

NOTE

If you consider adding a LCD Meter at a later date, the electronics-side of the transmitter should be mounted in a visible position

2-8

Tagging Commissioning Tag

The transmitter has been supplied with a removable commissioning tag that contains both the Device ID and a space to record the device tag. The Device ID is a unique code that identifies a particular device in the absence of a device tag. The device tag is used as an operational identification for the device and is usually defined by the Piping and Instrumentation Diagram (P & ID).

When commissioning more than one device on a fieldbus segment, it can be difficult to identify which device is at a particular location. The removable tag provided with the transmitter can aid in this process by linking the Device ID and a physical location for each transmitter on the segment. The installer should note the transmitter’s physical location on both the removable commissioning tag and the bottom portion of the tag, which can be torn off. The bottom portion of the tags can be used for commissioning the segment in the control system.

ENVIRONMENTAL CONSIDERATIONS

Tem perature Effects See Table 2-1.

Aside from ambient temperature variations, process-induced temperature in a direct mounting configuration is transferred from the thermowell to the transmitter housing. If the expected process temperature is near or beyond specification limits, consider using an additional thermowell lagging, an extension nipple, or a remote mounting configuration to isolate the transmitter from these excessive temperatures. Figure 2-8 provides an example of the relationship between transmitter housing temperature rise and extension length. Use Figure 2-8 and the accompanying example to determine adequate thermowell extension length.

T = S – A T = 85 °C – 40 °C T = 45 °C

For a process temperature of 540 °C, an extension length of 3.6 inches yields a housing temperature rise (R) of 22 °C, which provides a safety margin of 23 °C. A six-inch extension length (R = 10 °C) would offer a higher safety margin (35 °C) and would reduce temperature-effect errors but would probably require extra support for the transmitter. Gauge the requirements for individual applications along this scale. If a thermowell with lagging is used, the extension length may be reduced by the length of the lagging.

Moist or Corros ive Environments

The Model 3244MV has a highly reliable, dual-compartment housing designed to resist moisture and corrosives. The electronics module assembly is mounted in a compartment that is isolated from the terminal side conduit entries. When covers are installed correctly, o-ring seals protect the interior of each compartment from the environment. However, in humid environments it is possible for moisture to accumulate in conduit lines and drain into the housing.

2-11

Rosemount Model 3244MV MultiVariable Temperature Transmitter with Foundation Fieldbus

Proper installation of the transmitter ensures maximum operation and service life. It can also have a significant impact on preventing moisture from accumulating in the housing. Refer to Figure 2-9 before mounting the transmitter.

If possible, mount the transmitter at a high point in the conduit run so moisture from the conduits will not drain into the housing. If the transmitter is mounted at a low point, the terminal compartment could fill with water. In some instances the installation of a poured conduit seal, such as the one pictured in Figure 2-10, is advisable. Periodically remove the terminal compartment cover and inspect the transmitter for moisture and corrosion.

The Model 3244MV is designed with an explosion-proof housing and circuitry suitable for intrinsically safe and non-incendive operation. When specified, each transmitter is marked with an approval label. To maintain certified ratings, install in accordance with all applicable installation codes and approval drawings (Section 8: Hazardous Area Approval Installation Drawings). Verify that the atmosphere in which the transmitter operates is consistent with the appropriate hazardous location certifications. Both transmitter covers must be fully engaged to meet explosion-proof requirements.

Each FOUNDATION fieldbus host or configuration tool has a different way of displaying and performing configurations. Some will use Device Descriptions (DD) and DD Methods to make configurations and to display data consistently across platforms. There is no requirement that a host or configuration tool support these features.

NOTE

The information in this section will describe how to manually configure the Model 3244MV. For information regarding the implementation of these common functions using the DeltaV System with AMSinside from Fisher-Rosemount, refer Appendix G: Operation with Fisher-Rosemount® DeltaV™.

For more information about the FOUNDATION fieldbus technology and the function blocks used in the Model 3244MV, refer to Section 4: Transducer Block, Section 5: Resource Block, and Appendix A: Foundation™ Fieldbus Technology through Appendix H: European ATEX Directive Information.

DEVICE TAG AND NODE ADDRESS

Unless a device tag name is specifically ordered, the transmitter is shipped with a default device tag. All devices are shipped with a temporary address (between 25P and 25I). This allows the host to automatically commission the transmitter. If the tag or address changes, use the configuration tool to perform the following functions:

1. Change the address to a temporary address (between 248 and 251).

2. Change the tag to a new value.

3. Change the address to a 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.

TEMPERATURE SP ECIFIC BLOCK CONFIGURATION

Only the Transducer Block, Analog Input function blocks, and Input Selector function block have configurations for temperature-specific parameters. Other function blocks that are used for control and/or monitoring applications are configured by links made from the Analog Input (and/or Input Selector) block. See Appendix B: Analog Input Function Blockfor specific application examples.

Transducer Block The sensor type and connections for the Transducer Block have been

preconfigured at the factory according to customer selected specifications (see below table).

NOTE

If only one single-element sensor is used but both sensor 1 and sensor 2 are configured, PRIMARY_VALUE_2 will have a status of bad and a substatus of sensor failure and DIFFERENTIAL_TEMPERATURE will have a status of bad and substatus of not specific.

Operation

See Section 4: Transducer Block for more details on configuring and troubleshooting the Transducer Block.

Back-up LAS The model 3244MV comes as a Link Master (LM) class device. With this

feature, the Model 3244MV can become a fully functioning Link Active Scheduler (LAS) in the event that the primary LAS (typically the host system) fails. Appendix A: Foundation™ Fieldbus Technology provides a detailed explanation of the communications and LAS features and parameters.

Analog Input Function Block

The Analog Input (AI) function block provides the link that communicates the to the F

OUNDATION fieldbus. The interface between each AI block and

temperature measurement in the transducer block

the transducer block is through the three parameters that are listed below. These parameters have already been preconfigured at the factory according to your specified configuration. They can be changed in the field using any F

OUNDATION fieldbus host or configuration tool that

supports DD methods.When necessary, use the order indicated below to change these parameters:

1. CHANNEL: Defines which transducer block measurement is used by the AI block. For example, CHANNEL parameters for option code U1: Hot Backup (Control and Safety Applications) would be as follows:

ьяъшцхьффюэыщ ыъыучът ьяшцхьффюэыщ ыыучт ьяшцхьффюэыщ ыыу∆чт

2. XD_SCALE.UNITS_INDX: Defines the engineering units associated with the channel input value. Default configuration is °C for all AI blocks

3. L_TYPE: Determines whether the field value is used directly (Direct), converted linearly (Indirect), or is converted with the square root (Indirect Square Root). Since the temperature measurement from the transducer block is in the correct units, L_TYPE is configured as Direct. L_TYPE is usually only changed to Indirect or Indirect Square Root if the measurement type changes. For example, changing mV into temperature.

Input Selector Function Block

See Appendix B: Analog Input Function Block for more details on configuring and troubleshooting the AI blocks.

The Input Selector (ISEL) function block is used to output a specific selection strategy using inputs from AI function blocks. The ISEL block has already been preconfigured at the factory according to your specified transmitter configuration (see below table). The configuration can easily be changed in the field using any F

OUNDATION fieldbus host

or configuration tool that supports DD methods.

Fluid D ensity Application

The Model 3244MV available with an Arithmetic Function Block, which is useful in many types of temperature applications, such as calculating fluid density. Since many liquids are virtually incompressible fluids, temperature is often used as the main variable for determining fluid density. The temperature of the fluid can be converted into density by using the fourth order polynomial capability of the Arithmetic block.

Figure 3-16 shows the applicable links for the Arithmetic Function Block. In this example, the ARITH-TYPE parameter = Fourth order polynomial.

Sensor Drift Alert Configuration

The Sensor Drift Alert configuration feature aids in the prediction of sensor failures. This feature should be used when measuring the same process temperature, such as with a dual-element sensor.

Use the following steps to set up Sensor Drift Alert:

1. Assign an AI block to the differential temperature measurement in the Transducer Block. When the sensors are working properly, the differential temperature should be near zero.

2. Set the maximum allowable temperature difference (drift) between sensor 1 and sensor 2 by setting the alarm limit parameters HI_LIM and LO_LIM in the AI block.

NOTE:

If Custom Configuration Options U1, U6, U7, U8, or U9 are ordered, the AI3 alarm parameters are preconfigured as follows: HI_LIM = 5.4 °F (3.0 °C) LO_LIM = –5.4 °F (–3.0 °C)

3. An alert is generated when the transmitter detects a temperature difference that exceeds the alarm limits.

Figure 3-18. Sensor Drift Alert Diagram

4. Additional bands of drift can be configured by using HI_HI_LIM and LO_LO_LIM. This is done to identify warning and failure points in a temperature application.

Definition The Transducer Block contains temperature measurement data,

including Sensor 1, Sensor 2, differential, and terminal temperatures. Channels 1–4 are assigned to these temperature measurements (see Figure 4-1 above). The Transducer Block also includes information about sensor type, engineering units, linearization, reranging, damping, temperature compensation, and diagnostics.

Channel Definitions The Model 3244MV supports multiple sensor inputs. Each input has a

channel assigned to it that allows the AI block to link to it. The channels for the Model 3244MV are as follows:

• Channel T1 (Sensor 1 temperature)

• Channel TT (Terminal temperature)

• Channel T2

(Sensor 2 temperature)

• Channel DT = T1 – T2 (Differential temperature)

NOTE

Whenever the transducer block is configured with 2 inputs the Differential Temperature (DT) is calculated.

Modes The transducer block supports two modes of operation as defined by the

MODE_BLK Parameter: Automatic (Auto)—The channel outputs reflect the analog input

measurement. Out of Service (O/S)—The block is not processed. Channel outputs

are not updated and the status is set to Bad: Out of Service for each channel. 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.

Alarm Detection Alarms are not generated by the transducer block. By correctly

handling the status of the channel values, the down stream block (AI) will generate the necessary alarms for the measurement. The error that generated this alarm can be determined by looking at BLOCK_ERR and XD_ERROR.

Status Handling Normally, the status of the output channels reflects the status of the

measurement value, the operating condition of the measurement electronics card, and any active alarm condition.

In Auto mode, OUT reflects the value and status quality of the output channels.

Transmitter-

Sensor Matching

Callendar-Van Dusen constants from a calibrated RTD schedule can be loaded into the Model 3244MV. A special curve is generated in the device that matches the specific sensor to the measured input of the RTD. This sensor matching enhances the accuracy of temperature sensor measurement. The Callendar-Van Dusen constants are input using the Sensor Type DD method. Selecting the User Defined sensor type will allow you to enter the constants. These can either be entered in the form of R

, Alpha, Beta, Delta, or the form of R0, A, B, C. See the

section on page 8 for more details on selecting the sensor type.

Resource Block

Alarm Detection A block alarm will be generated whenever the BLOCK_ERR has an

error bit set. The types of block error for the resource block are defined above. A write alarm is generated whenever the WRITE_LOCK parameter is cleared. The priority of the write alarm is set in the following parameter:

• WRITE_PRI

Alarms are grouped into five levels of priority:

Priority Number Priority Description

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).

Status Handling There are no status parameters associated with the resource block. LCD Meter Display The Model 3244MV has the ability to locally display all measurements

in the Transducer Block including Sensor 1, Sensor 2, differential and terminal temperatures. The display alternates between the selected measurements. The meter can display up to five digits in engineering units (°F, °C, °R, K, Ω, and millivolts) and milliamperes (mA).

Display settings are preconfigured at the factory according to the transmitter configuration (standard or custom). The decimal point default configuration is a floating point value. These settings can be reconfigured in the field using a F

tool. This is done by selecting from the following list of DISPLAY_MODE parameter values.

• T1 (Sensor 1 temperature)

• T2 (Sensor 2 temperature)

• Diff T (Differential Temperature)

• PRT (Terminal Temperature)

• 1 Decimal Place

• 2 Decimal Places

• 3 Decimal Places

• 4 Decimal Places

NOTE

When ordering a spare electronics module assembly, the DISPLAY_MODE parameter will not be configured and the LCD meter will display "Set up Display." Configure the DISPLAY_MODE parameter to remove this message from the display.

HARDWARE MAINTENANCE

The Model 3244MV transmitter has no moving parts and requires a minimum amount of scheduled maintenance. The transmitter features a modular design for easy maintenance. If you suspect a malfunction, check for an external cause before performing the diagnostics presented below.

Sensor Checkout If the sensor is installed in a high-voltage environment and a fault

condition or installation error occurs, the sensor leads and transmitter terminals could carry lethal voltages. Use extreme caution when making contact with the leads and terminals.

To determine whether the sensor is causing the malfunction, either replace it with another Rosemount sensor or connect a test sensor locally at the transmitter. This can be very useful, especially when checking the wiring for a remote mounted sensor. Please consult your local Rosemount representative for additional assistance with your temperature sensor and accessory needs.

Rosemount Conformance to SpecificationS

You can be confident that a Rosemount product not only meets its published specifications, but most likely exceeds them. Our advanced manufacturing techniques and use of Statistical Process Control provide specification conformance to at least ± 3s commitment to continual improvement ensures that product design, reliability, and performance get better every year.

For example, the Reference Accuracy distribution for the Model 3244MV MultiVariable Temperature Transmitterwith F fieldbus is shown to the right. but, as the shaded area shows, approximately 68% of the units perform three times better than the limits. Therefore, it is very likely that you will receive a device that performs much better than our published specifications.

Conversely, a vendor who “grades” product without using Process Control, or who is not committedto ± 3s performance, will ship a much higherpercentage of units that are barely within (or even outside of) advertised specification limits.

Self Calibration The analog-to-digital circuitry automatically self-calibrates for each

temperature update. The circuitry compares the dynamic measurement to the extremely stable and accurate internal reference elements.

Ambient Temperature Effect

Refer to Table 7-4, Table 7-5, and Table 7-6 on page 7-8. The Model 3244MV can be installed in locations where the ambient

temperature is between –40 and 85 °C (–40 and 185 °F). At the factory each transmitter is individually characterized over this ambient temperature range to maintain excellent accuracy performance in dynamic industrial environments. This special manufacturing technique is accomplished through extreme hot and cold temperature profiling with individual adjustment factors programmed into each transmitter. The transmitter automatically adjusts to encompass component drift caused by changing environmental conditions.

Differential capability exists between any two sensor types:

• For all differential configurations, the input range is X to +Y where

X Sensor 1 minimum Sensor 2 maximum–= Y Sensor1 maximum Sensor 2 minimum–=

Accuracy for differe ntial configura tions:

• If sensor types are similar (for example, both RTDs or both thermocouples), the accuracy = 1.5 times worst case accuracy of either sensor type.

• If sensor types are dissimilar (for example, one RTD and one thermocouple), the accuracy = Sensor 1 accuracy + Sensor 2 accuracy.

Using Thermocouples in noncritical and differential temperature applications:

• Two independently-grounded thermocouples could create ground loops, resulting in measurement errors. Avoid using two independently grounded thermocouples.

Fieldbus

Technology

OVERVIEW This section introduces fieldbus systems that are common to all

fieldbus devices.

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 Fieldbus Foundation 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.

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

™

Fieldbus F addressing a different need.

OUNDATION has designed a range of function blocks, each

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 Fieldbus F defining a small set of parameters used in all function blocks called universal parameters. The F 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.

The F

OUNDATION 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 A-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.

OUNDATION has established the function blocks by

OUNDATION has also defined a standard set

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.

FIELDBUS_0012

Function blocks are also capable of performing short-term data collection and storage for reviewing their behavior.

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.

Foundation™Fieldbus Technology

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.

Instrument- Specif ic 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.

T r ansducer 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.

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.

NETWORK COMMUNICATION

Figure A-2. Simple, Single-Link FieldbusNetwork

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.

Figure A-2 illustrates a simple fieldbus network consisting of a single segment (link).

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 management to synchronize function block execution with the data transfers 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.

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.

There may be many Link Master (LM) devices on a segment but only the LAS is actively controlling communication traffic. The remaining LM devices on the segment are in a stand-by state, ready to take over if the primary LAS fails. A secondary LM device becomes the primary LAS if it recognizes that the primary LAS device fails. This is achieved by constantly monitoring the communication traffic on the bus and determining if activity is not present. Since there can be multiple LM devices on the segment when the primary LAS fails, the device with the lowest node address (described below) will become the primary LAS and take control of the bus. Using this strategy, multiple LAS failures can be handled with no loss of the LAS capability of the communications bus.

Foundation™Fieldbus Technology

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 Fisher-Rosemount 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.

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 broadcast. Transfers of this type can be scheduled on a precisely periodic 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. Transfers of this type are queued. They are delivered to the receivers in the order transmitted, although there may be gaps due to corrupted 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 overwriting previous messages. However, unlike Report Distribution, these transfers are flow controlled and employ a retransmission procedure to recover from corrupted transfers.

Figure A-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.”

Unscheduled Transfers Figure A-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.

Function Block Scheduling Figure A-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.

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.

LAS Paramet er s There are many bus communication parameters but only a few are

used. For standard RS-232 communications, the configuration parameters are baud rate, start / stop bits, and parity. The key parameters for H1 Fieldbus are Slot Time (ST), Minimum Inter-PDU Delay (MID), Maximum Response (MRD), and Time Synchronization Class (TSC).

FIELDBUS_0016

ST is used during the bus master election process. It is the maximum amount of time permitted for device A to send a Fieldbus message to device B. Slot time is a parameter which defines a worst case delay which includes internal delay in the sending device and the receiving device. Increasing the value of ST slows down bus traffic because a LAS device must wait longer prior to determining that the LM is down.

A-7

Rosemount Model 3244MV MultiVariable Temperature Transmitter with Foundation Fieldbus

MID is the minimum gap between two messages on the Field bus segment or it is the amount of time between the last byte of one message and the first byte of the next message. The units of the MID are octets. An octet is 256 µs, hence the units for MID are approximately

/4 ms. This would mean an MID of 16 would specify approximately a minimum of 4 ms between messages on the Fieldbus. Increasing the value of MID slows down bus traffic because a larger “gap” between messages occurs.

MRD defines the maximum amount of time permitted to respond to an immediate response request, e.g. CD, PT. When a published value is requested using the CD command, the MRD defines how long before the device publishes the data. Increasing this parameter will slow down the bus traffic by slowing down how fast CDs can be put onto the network. The MRD is measured in units of ST.

TSC is a variable that defines how long the device can estimate its time before drifting out of specific limits. The LM will periodically send out a time update messages to synchronize devices on the segment. Decreasing the parameter number increases the amount of time that a messages must be published, increasing bus traffic and overhead for the LM device. See Figure A-6.

Back-up Las

A Link Master (LM) device is one that has the ability to control the communications on the bus. The Link Active scheduler (LAS) is the LM capable device that is currently in control of the bus. While there can be many LM devices acting as back-ups, there can only be one LAS. The LAS is typically a host system but for stand-alone applications, a device may be providing the role of primary LAS.

B Analog Input Function Block

OUT_D

OUT=The block output value and status OUT_D=Discrete output that signals a selected alarm condition

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.

The AI block supports alarming, signal scaling, signal filtering, signal status calculation, mode control, and simulation. In Automatic mode, the block’s 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 B-4 illustrates the internal components of the AI function block, and Table B-1 on page -2 lists the AI block parameters and their units of measure, descriptions, and index numbers.
