What the FLEX I/O Analog
I/O Modules Do
The 1794 HART input and output modules must be used in a ControlNet or
EtherNet network.
The 1794-IE8H module accepts up to 8 analog inputs. The inputs are nonisolated and will accept current in either of the following two ranges: 4 to
20 mA or 0 to 20 mA. The default input range is 0 to 20 mA. The inputs have both fixed hardware filters and selectable firmware digital filters.
Similarly, the 1794-OE8H module provides as many as 8 analog outputs. The outputs are nonisolated and will provide current in either of the following two ranges: 4 to 20 mA or 0 to 20 mA. The default output range is 0 to 20 mA.
Each module offers:
• local microprocessor intelligence for advanced features.
• full functionality without switches or jumpers.
• multiple data ranges that can be independently programmed in channel groups.
• lead breakage detection.
• overrange/underrange alarms.
• remote transmitter alarm.

1-2 About the FLEX I/O HART Analog Modules
How FLEX I/O Analog
Modules
Communicate with
Programmable Controllers
FLEX I/O analog modules provide best utility when used with ControlNet products on the ControlNet network. Data connections are established between the I/O module and an Allen-Bradley programmable controller
(PLC) to transfer information between the two at a scheduled rate.
Input module information is then automatically made available in the PLC data table through the data connection. Reciprocally, output data information determined by the PLC program is also automatically transferred from the
PLC data table to the output module through the data connection.
In addition, when the data connection is originally established, configuration information for the module is automatically transferred to it via the network.
Events Following Power-up
You must apply +24V dc power to your FLEX I/O analog I/O modules. The following sequence of events occurs after power has initially been applied to your module:
1. The module begins an internal diagnostic check. The channel 0 indicator turns ON to indicate the check has begun. The indicator turns OFF when the check is finished.
2. After the diagnostic check, module configuration information, selected by the user and downloaded over the network, is applied by the module.
For more information on configuration options, see Chapter 2.
3. Following the module configuration download for the 1794-IE8H module, the module begins producing runtime data for the PLC processor.
Following the module configuration download for the 1794-OE8H module, the module applies configuration data to output channels.
4. If any diagnostics or alarms are generated during normal module operation, the data is returned to the PLC processor.

Use Alarms on the
1794-IE8H Module
The 1794-IE8H FLEX I/O module is capable of generating four alarms:
• Underrange
• Overrange
• Remote Fault
• Local Fault
These alarm conditions are described in general terms and as they relate to bits on the FLEX I/O module on the following pages. The following graphic shows at what values these alarms are generated for Data Format 4.

Overrange Alarm
The overrange alarm notifies you when module input is overrange. When the input signal exceeds 100% (20 mA), an Overrange Alarm is generated.
This alarm stays active at any value above 100% of range and is always enabled by the module.
Underrange Alarm
The underrange alarm works converse to the overrange. This feature notifies you when the input signal falls underrange. If the input signal falls below 0% (4 mA), an Underrange Alarm is generated.
This alarm stays active at any value below 0% of range and is always enabled by the module.
Publication 1794-UM063A-EN-P - March 2006
About the FLEX I/O HART Analog Modules 1-5
Remote Fault Alarm
The remote fault alarm is intended for use with remote transmitter loops.
For example, the remote transmitter may be measuring temperature and converting it to a standard mA signal. In such a loop, though, the input module cannot determine the state of the loop on the far side of the transmitter.
However, the remote transmitter may be capable of diagnosing a problem in the remote loop and signal the input module local loop with a preprogrammed out of range (high or low) value.
The remote fault alarm allows the 1794-IE8H module to work with transmitters like the one just described. You must use the Remote Transmitter
Error Up or Down feature, see page 2-2, to configure your application for
Remote Fault notification.
For example, you must determine if you want a remote fault to cause high out-of-range values or low out-of-range values to be returned to the controller.
IMPORTANT
Once the alarm is issued, it remains active as long as the input signal value remains above the programmed value.
Use Remote Fault Alarm to Determine High-High or Low-Low Alarm Levels
If you do not have a remote transmitter in your loop, this alarm can also be used to program a high-high or low-low alarm level between the levels which actuate the overrange or underrange alarms and the high or low local fault alarms.
IMPORTANT
When establishing high-high or low-low alarms, you can only select one side (high or low). You must use the Remote
Transmitter Error Up or Down feature in conjunction with this alarm.
Publication 1794-UM063A-EN-P - March 2006
1-6 About the FLEX I/O HART Analog Modules
Programming the Remote Fault Alarm
For the remote fault alarm, you must program the threshold in 0.1 mA steps at any level on the high or low end of input signal range. The remote fault alarm activates if your I/O module receives input signal values of:
• 100.63 to 111.88% (20.1 to 21.9 mA) on the high end of input signal range or
• -0.63 to -11.88% (3.9 to 2.1 mA) on the low end of input signal range
IMPORTANT
This alarm is only active for one band, either on the high side of normal operation or the low side.The Remote Transmitter Error Up/Down parameter
determines which side is active. See page 2-2 for a description of the
Remote Transmitter Error Up/Down feature.
Local Fault Alarm
The local fault alarm notifies you when the loop to the transmitter or field device, if no transmitter is used, is open or shorted.
IMPORTANT
Once the alarm is issued, it remains active as long as the input signal value remains in the programmed range.
• 112.50% (22 mA) or higher on the high end of input signal range.
This value indicates a short in the loop.
or
• -12.50% (2 mA) or lower on the low end of input signal range.
This value indicates an open wire condition in the loop.
The remote fault and local fault alarms are issued with the same bit whether the cause is an under or overrange. Monitor the overrange and underrange bits in your programming software to determine if the problem is a high current or low current.

How to Use the
HART Capabilities
HART Implementation
Overview
About the FLEX I/O HART Analog Modules 1-7
Before using the HART capabilities, be sure that:
• the I/O module and the associated field device are working properly in the analog 4 to 20 mA mode.
• the I/O module is configured for 4 to 20 mA range.
• the field device is HART capable.
• no more than one HART field device is connected to each channel.
• input filtering is set to a valid (defined) value.
The FLEX I/O HART modules act as intelligent HART multiplexers.
Basically, the module learns which HART devices are attached to its channels and then routes HART messages, as appropriate, between the HART field devices and the flexbus. Since the HART modules act as intelligent HART multiplexers, HART commands can be issued to the HART modules themselves.
Communication on the flexbus occurs between the adapter and the HART module. The adapter converts these messages to the appropriate network format for communication with the controlling processor. The controlling processor gets its command from the user program, storing the responses in its memory.

2-2 Configurable FLEX I/O Analog Module Features
IMPORTANT
You must use the I/O configuration portion of your PLC programming software to select and configure these features.
This manual assumes familiarity with the programming software. A brief description of each module feature is provided here. For more information on your programming software, see the software user manual.
Select Your 1794-IE8H
FLEX I/O Analog Input
Module’s Operating
Features
All features of the 1794-IE8H analog input module are independently configurable in two four-channel groups (channel 0 to 3 & channel 4 to 7).
IMPORTANT
The default selection value for all parameters is 0.
Fault Mode
Your input modules are capable of indicating various fault conditions, depending on the input signal value. Use the Fault Mode feature to enable or disable two alarms:
• Remote Fault alarm
• Local Fault alarm
Use your programming software to set the Fault mode bit to 0 to disable these alarms. Set the bit to 1 to enable them.
IMPORTANT
Fault mode will only enable or disable the Remote and Local
Fault alarms. It does not affect the Underrange and Overrange alarms. They are always active.
For more information on the Remote Fault Alarm, see page 1-5. For more
information on the Local Fault Alarm, see page 1-6.
Remote Transmitter Error Up or Down
A second feature of your input module that affects use of the Remote Fault alarm is the Remote Transmitter Error Up or Down feature. Used in conjunction with the High Low Error level, this feature designates whether remote faults are displayed with input signal readings beyond the high or low signal levels normally used by the module.
Publication 1794-UM063A-EN-P - March 2006
Configurable FLEX I/O Analog Module Features 2-3
When setting the Remote Transmitter Error Up or Down feature in your programming software, set this feature’s bit to 0 to select up. Set the bit to 1 to select down.
For more information on the Remote Fault Alarm, see page 1-5. For more
information on the Local Fault Alarm, see page 1-6.
High Low Error Level
High Low Error level sets the high and low signal levels at which your input modules will indicate a signal fault. This feature works in conjunction with the
Remote Transmitter Error Up or Down.
If the Remote Fault Alarm feature is enabled and a remote fault occurs, the module will detect and report the fault, depending on how the High Low
Error level is configured.
Use your programming software to set the high or low error levels.
Input Filter Cutoff
Eight available input filter settings allow you to choose the best rolloff frequency for input channels on your I/O module. When choosing a filter, remember that time filter selection affects your input signal’s accuracy.
For example, if you choose the highest frequency of 10 Hz (filter 3), signal noise is more likely to affect the reading, but the slowest frequency of 0.5 Hz (filter 7) provides the most accurate signal due to incoming noise filtering.
See Table 2.2 to decide which input filter to use in your FLEX I/O
analog I/O application:

FLEX I/O Analog Output
Module’s Operating
Features
Configurable FLEX I/O Analog Module Features 2-7
All features of the 1794-OE8H analog output module are independently configurable in two four-channel groups (channel 0 to 3 and channel 4 to 7).
IMPORTANT
The default selection value for all parameters is 0.
Local Fault Mode
The Local Fault Mode can be programmed to determine how the module responds to communications faults and internal module faults.
When setting the Local Fault Mode feature in your programming software, set this feature’s bit to 0 to use the analog fault state or digital fault state only if a communications fault occurs. Set the bit to 1 to use the Analog Fault state or
Digital Fault state if any fault occurs.
Latch Mode
Latch Mode determines channel operation under wire-off or lead-break fault conditions. This feature controls the operation of two channel groups, channels 0 to 3 and channels 4 to 7. Channel detection occurs on a continuous basis. If a fault is detected, the channel fault alarm is set.
If Latch mode is enabled when a fault occurs, the fault will remain latched in its fault state until a Global Reset (see below) is issued. If Latch mode is disabled when a fault occurs, the channel reports a fault until the fault is corrected. Global Reset is not necessary if Latch mode is disabled.
When using your programming software, set the Latch mode bit to 0 to disable the feature. Set the bit to 1 to enable it.
Global Reset
Global Reset works in conjunction with Latch mode during fault conditions. If
Latch mode is enabled and a fault condition occurs, the channel operating with a fault remains in this condition (with analog or digital fault state implied) until a Global Reset is issued. The Global Reset feature resets all outputs of a particular channel group to accept normal system output data.
The Global Reset feature is an edge triggered signal. Use your programming software to set the Global Reset bit to 1 for normal operation. Resetting of outputs occurs during the 1 to 0 transition.
Publication 1794-UM063A-EN-P - March 2006
2-8 Configurable FLEX I/O Analog Module Features
Analog Digital State
You can configure your FLEX I/O analog output modules to work in an analog mode or digital mode using the Analog Digital State feature. Depending on which state you choose for your application, additional parameters (see the
descriptions of Analog Fault State and Digital Fault State on page 2-8) must be
configured for your module to react to fault conditions.
Set the Analog Digital State bit in your programming software to 0 for your module to operate in an analog state. Set the bit to 1 for your module to operate in a digital state. A selection bit is available to each channel.
Analog Fault State
The Analog Fault State feature determines how your I/O module reacts to faults when a channel is used in analog mode. After a fault condition occurs, the module may got to minimum value, maximum value, hold last state or use analog fault state value.
Use your programming software to set the Analog Fault State bits on the
I/O module for one of the following fault reactions:
• 0 = minimum value
• 1 = maximum value
• 2 = hold last state
• 3 = use analog fault state value
You can set these parameters independently for channels 0 to 1, 2 to 3, 4 to 5, and 6 to 7.
Analog Fault State Value
Specifies the fault state value of the analog output data to the module. Specific format is controlled by the Module Data Format Control parameter. This data is used when the channel is in analog output mode and the analog fault state is configured to use analog fault state value.
Digital Fault State
The Digital Fault State feature determines how your I/O module reacts to faults when a channel is used in digital mode. After a fault condition occurs, the module may reset channel outputs or hold last state of the outputs.
Use your programming software to set the Digital Fault State bit to 0 to reset outputs. Set to 1 to hold last state of the outputs after a fault occurs. This feature is available on a per channel basis.
Publication 1794-UM063A-EN-P - March 2006
Configurable FLEX I/O Analog Module Features 2-9
Data Format
You must choose a module data format in your user program. See
1794-OE8H Data Formats on page 2-10 for an explanation of each bit. Data
Formats 2, 5, 6, 8, 9, 10, 12 and 15 are not assigned.
When choosing a data format, remember the following:
• If an unassigned Analog Data Format is selected, the module sets
Diagnostic Data to 2 for configuration failure and puts affected channels affected in the corresponding fault state.
• An unconfigured module channel pair can be assumed to have the default configuration Analog Data Format 0, 0 to 20 mA and Analog
Mode Fault State minimum range. If a non-assigned format is selected, then the diagnostic 2 for configuration failure is set and the module channel pair goes to the default fault state minimum range.
• If on the other hand, the configuration had been changed, from the default, and then it was changed again to a non-assigned format, then the diagnostic bit 2 for configuration failure is set and the module goes to the fault state for the last valid configuration.
• Formats 13 and 14 are 2’s complement data formats, and require data to the module in that form.
• Range: 0 to 15
• Default: 0
• Data Table Reference: data format, word 12 and 13, bits 0 to 3, bits 4 to 7
If data is sent to the module which is out of range, the value will be clipped and
Diagnostic Data will be set to 11 data out of range.

HART Read Back Threshold
This bit delivers the percentage value, in steps of 1%, of the threshold for forcing the HART read back indication. The maximum input signal deviation for HART analog modules is 31%.
If there is no HART transmitter on the loop or if the loop is not in the transmitter list, the function is switched off internally in the I/O module.
The values are:
• 0 = disable indicator (default)
• 1 to 4 = not supported from the I/O module (set to 5 internally)
• 5 to 31 = percentage threshold data (5 to 31%)
In this chapter, we told you about the FLEX I/O system and the analog I/O modules, and how they communicate with programmable controllers. Move to

Removal and Insertion
Under Power
WARNING
These module are designed so you can remove and insert them under power. However, take special care when removing or inserting these modules in an active process. I/O attached to any module being removed or inserted can change states due to its input/output signal changing conditions.
If you insert or remove the terminal base while backplane power is on, an electrical arc can occur. This could cause an explosion in hazardous location installations.
Be sure that power is removed or the area is nonhazardous before proceeding.
Install the Module
WARNING
When used in a class I, division 2, hazardous location, this equipment must be mounted in a suitable enclosure with proper wiring method that complies with the governing electrical codes.
Installation of the analog module consists of the following.
• Mounting the terminal base unit.
• Installing the analog I/O module into the terminal base unit.
• Installing the connecting wiring to the terminal base unit.
If you are installing your module into a terminal base unit that is already installed, proceed to “Mount the Analog Modules on the Terminal Base” on
Do not use the unused terminals on the terminal base unit.
Using the terminals as supporting terminals can result in damage to modules and/or unintended operation of your system.

Slide the terminal base over tight against the adapter (or proceeding terminal base). Make sure the hook on the terminal base slides under the edge of the adapter (or proceeding terminal base) and the flexbus connector is fully retracted.
Do not force the terminal base into the adjacent modules.
Forcing the units together can bend or break the hook and allow the units to separate and break communication over the backplane.
5. Rotate the terminal base onto the DIN rail with the top of the rail hooked under the lip on the rear of the terminal base.
Use caution to make sure that the female flexbus connector does not strike any of the pins in the mating male connector.
41108
Press down on the terminal base unit to lock the terminal base on the DIN rail. If the terminal base does not lock into place, use a screwdriver or similar device to open the locking tab, press down on the terminal base until flush with the DIN rail and release the locking tab to lock the base in place.

FLEX I/O HART Analog
Modules
Wiring the FLEX I/O HART analog input modules is done using the
1794-TB3G or the 1794-TB3GS terminal base unit..
The FLEX I/O analog modules do not receive primary operational power from the backplane. +24V dc power must be applied to your module before operation. If power is not applied, the module position will appear to the adapter as an empty slot in your chassis. If the adapter does not recognize your module after installation is completed, cycle power to the adapter.
Inputs/Outputs
Each 1794-IE8H input can be operated from an analog field device signal, and each 1794-OE8H output channel can operate an analog field device.
The channels of the 1794-IE8H are electrically connected to each other and have a common plus-line. The channels of the 1794-OE8H are electrically connected to each other.
IMPORTANT
When interconnecting several lines, you must consider the total accumulated power.

4-2 Input, Output and Configuration Files for the Analog I/O Modules on the ControlNet Network
Use Programming Software in Your FLEX I/O Application
When using FLEX I/O analog modules, you must perform I/O mapping and configure the ControlNet network before generating configuration data for your I/O modules.
For example, you may use RSNetWorx software to connect FLEX I/O modules to a ControlNet processor or scanner through a FLEX I/O
ControlNet adapter (cat. no. 1794-ACNR15). The I/O configuration portion of another programming software, for example RSLogix5 software, could be used to generate the configuration data for each I/O module in the control system.
Configuration data is transferred from the controller to the I/O modules when communication to the modules is first established.
Follow these general guidelines when configuring I/O modules.
1. Perform I/O mapping.
2. Configure all I/O modules.
3. Change to Run mode to initiate communication.
4. Download module configuration.
About the ControlNet
Adapter
The FLEX I/O ControlNet adapter interfaces up to 8 FLEX I/O modules to a ControlNet processor or scanner. The adapter can support ControlNet real-time data connections to individual modules or module groups. Each connection is independent of the others and can be from different processors or scanners.

Communication Over the
FLEX I/O Backplane
Network
One 1794-ACNR15/B ControlNet adapter can interface up to eight terminal base units with installed FLEX I/O modules, forming a FLEX I/O system of up to eight slots.
The adapter communicates to other network system components (typically one or more controllers, scanners, or programming terminals) over the
ControlNet network. The adapter communicates with its I/O modules over the FLEX I/O backplane.

• is continuous.
• is asynchronous to the controller program scan.
• occurs at the actual rate displayed in the Actual Packet Interval field on the programming software ControlNet I/O mapping (monitor) screen.

Unscheduled Data Transfer
Unscheduled operations include:
• unscheduled nondiscrete I/O data transfers–through ControlNet I/O
Transfer (CIO) instructions.
• peer-to-peer messaging–through message (MSG) instructions.
• messaging from programming devices.
Unscheduled messaging on a ControlNet network is nondeterministic. Your application and your configuration (for example, number of nodes, application program, NUT, and amount of scheduled bandwidth used), determine how much time there is for unscheduled messaging.
Module I/O Mapping
The I/O map for a module is divided into read words and write words. Read words consist of input and status words, and write words consist of output and configuration words. The number of read words or write words can be 0 or more.
The length of each I/O module’s read words and write words vary in size depending on module complexity. Each I/O module will support at least 1 input word or 1 output word. Status and configuration are optional, depending on the module.
I/O Structure
Output data is received by the adapter in the order of the installed I/O modules. The output data for slot 0 is received first, followed by the output data for slot 1, and so on up to slot 7.
Input data is sent by the adapter. The first word is the Adapter status word.
This is followed by the input data from each slot, in the order of the installed
I/O modules. The input data from slot 0 is first after the status word, followed by input data from slot 1, and so on up to slot 7.

Possible causes for an I/O module fault are:
• Transmission errors on the FLEX I/O backplane
• Failed module
• Module removed from its terminal base
• Incorrect module inserted in a slot position
• Slot is empty
• Slot contains a non-digital module
Fault State Data
The FLEX I/O HART modules provides storage for alternate module output data during communication faults or processor idle state. This fault state data assures that a known output will be applied to the output devices during the previously mentioned modes.
The processor or scanner software must include the means to specify this fault state data for each module. If applicable, this data is sent in the configuration
block, see Image Table Mapping on page 2-12.

Device Actions
Input, Output and Configuration Files for the Analog I/O Modules on the ControlNet Network 4-7
Device actions include:
• Communication fault behavior
• Idle state behavior
• Input data behavior upon module removal
Communication Fault Behavior
You can configure the response to a communication fault for each I/O module in its system. Upon detection of a communication fault, the module can:
• Leave the module output data in its last state (hold last state)
• Reset the module output data to zero (reset)
• Apply fault state data to the module output
Idle State Behavior
The FLEX I/O HART module can detect the state of the controlling processor or scanner. Only 2 states can be detected: Run mode, or Program mode (idle).
When Run mode is detected, the adapter copies the output data received from the processor to the corresponding module output. When Program mode is detected, the I/O module can be configured to:
• Leave the module output data in its last state (hold last state)
• Reset the module output data to zero (reset)
• Apply fault state data to the module output

IMPORTANT
This chapter provides a detailed method to perform module calibration with individual commands. This discussion is only given here to explain the general process.
In practice, you must use the I/O configuration portion of your programming software to calibrate your modules. The software executes the methodology explained here.
When and How to
Calibrate Your FLEX I/O
Analog I/O Module
Your module is shipped already calibrated. If a calibration check is required, the module must be in a FLEX I/O system.
Perform module calibration periodically, based on your application. Module calibration may also be required to remove module error due to aging of components in your system.

The following features are unique to the 1794-IE8H module:
• There are two different values per channel that need to be calibrated: gain and offset at room temperature (25 °C).
• All values are stored in the I/O module non-volatile EEPROM.
• You can calibrate each channel separately or a specified number of channels together in respect of one value.
• If an offset value is calibrated, the corresponding gain value is invalid because the gain value depends on the actual offset value. Therefore, calibrate the gain values after you calibrate the offset values.
• After calibration, the actual date must be transmitted to the IOM and stored in the module non-volatile.
• The whole calibration can be set to default values by sending a reset command. The default date is Jan,01,2000.
• A specified calibration value can be set to default by sending a reset command for that channel.
• There is a special command to store the whole calibration data from
RAM to EEPROM within the I/O module.
• If one value, except the calibration date, isn’t calibrated yet, or if you set one value to default, the I/O module displays a calibration error within the Real Time Data diagnostic field.

Calibration of the HART I/O module is performed using data structures and
MSG Ladder-logic instructions. The MSG instruction sends the data structure to a dedicated attribute in the FLEX HART I/O module and the associated response is read from the same attribute. The data structure contains commands and its associated parameters. Depending on the command, they are either writable or readable. Only one access, either read or write, is executable at a time.
The Calibration data structure has four members: Command, Item, Data1, and

5-10 Calibrate Your Module
1794-IE8H Calibration with Offset and Gain
You must calibrate the offset from a channel before gain is calibrated at the same channel, because the gain value depends on the offset value. During the calibration of offset, the corresponding gain value is declared invalid. Before all values are calibrated, there is a calibration error displayed within the Real
Time Data in the diagnostic status. After calibration is complete, the calibrated values are stored in the RAM area by the I/O module. Therefore, a store command is necessary to cause the I/O module to transfer the RAM content to the EEPROM.
Use the following guidelines when setting the offset and gain calibrations:
• To calibrate a channel according to offset, the corresponding channel must be sorted, or opened, so that flow is 0.00 mA.
• To calibrate a channel according to gain, the corresponding channel must be supplied with 20.00 mA.
• Set the I/O module ambient temperature in the range of 25(±5) °C.
• Check the calibration status to see if it is idle or erroneous before sending the calibration command by reading attribute 67 hex
.

What This Appendix
Contains
Protocol Overview
Read this appendix to learn the module commands to and from FLEX I/O
HART modules.
HART field communications protocol is widely accepted in the industry as the standard for digitally enhanced 4 to 20 mA communication with smart field instruments. The HART protocol message structure, command set, and status are discussed in this appendix.
The HART command set is organized into three groups and provides read/write access to a wide array of information available in smart field instruments:
• Universal commands provide access to information that is useful in normal plant operation such as the instrument manufacturer, model, tag, serial number, descriptor, range limits, and process variables. All
HART devices must implement universal commands.
• Common practice commands provide access to functions, which can be carried out by many devices though, not all.
• Device-specific commands provide access to functions that may be unique to a particular device.

Additional HART Protocol Information
What This Appendix
Contains
Message Structure
This appendix discusses the HART protocol and provides references for additional information about the protocol. The appendix provides:
• HART protocol background information
• Command practice command sets
• Extended command sets
• References to additional information
This section describes the transaction procedure, character coding, and message structure of the HART protocol. These correspond to layer 2, the data-link layer, of the OSI protocol reference model.
Master-slave Operation
HART is a master-slave protocol. This means that each message transaction is originated by the master; the slave (field) device only replies when it receives a command message addressed to it. The reply from the slave device acknowledges that the command has been received, and may contain data requested by the master.
Multiple Master Operation
The HART protocol allows for two active masters in a system, one primary and one secondary. The two masters have different addresses, therefore each can positively identify replies to its own command messages.
Publication 1794-UM063A-EN-P - March 2006
C-2 Additional HART Protocol Information
Transaction Procedure
HART is a half-duplex protocol; after completion of each message, the FSK carrier signal must be switched off, to allow the other station to transmit. The carrier control timing rules state that the carrier should be turned on not more than 5 bit times before the start of the message (that is, the preamble) and turned off not more than 5 bit times after the end of the last byte of the message (the checksum).
The master is responsible for controlling message transactions. If there is no reply to a command within the expected time, the master should retry the message. After a few retries, the master should abort the transaction, since presumably the slave device or the communication link has failed.
After each transaction is completed, the master should pause for a short time before sending another command, to allow an opportunity for the other master to break in if it wishes. This way, two masters (if they are present) take turns at communicating with the slave devices. Typical message lengths and delays allow two transactions per second.
Burst Mode (not supported)
To achieve a higher data rate, some field devices implement an optional burst mode. When switched into this mode, a slave device repeatedly sends a data message, as though it had received a specific command to do so. Special commands, 107, 108, and 109, are used to start and stop this mode of operation, and to choose which command should be assumed. If burst mode is implemented, commands 1, 2, and 3 must be supported; other commands are optional. There is a short pause after each burst message to allow a master device to send a command to stop the burst mode operation, or to initiate any other single transaction, after which burst messages will continue.
Generally, burst mode is only useful if there is just one field device attached to a pair of wires, since only one field device on a loop can be in burst mode at any one time. In burst mode, more than three messages can be transmitted per second.
The actual HART message between the FLEX I/O HART module and the field device follows the standard HART messaging protocol.

Preamble
The preamble is a number of hexadecimal FF characters that precede all frames sent to the HART field device. The size depends on the field devices being used, but it can be from 2 to 32 hexadecimal. The default is 10. The
Smart Transmitter Interface inserts the required preamble before each packet or frame transmission to the HART device. This is done automatically so you do not have to program the host processor to do this.
Start Character
The start character of a HART message indicates the frame’s format, the source of the message, and if it is using burst mode.

HART Address
The Smart Transmitter Interface addresses HART field devices using either a short or long frame address format, as specified by the HART delimiter byte.
A short frame address is one byte long. A long frame address is five bytes long and includes a unique 32-bit identifier encoded within each field device by the manufacturer.
HART field device addressing is device dependent. Some devices do not support long frame addressing while others only recognize short frame addressing for HART Command 0. In this situation, use HART Command 0 to determine the long frame address, and then use long frame addressing for al other HART commands. Consult the documentation provided with your field device for details about the addressing formats it supports.

HART Command
This one-byte field specifies the HART command that is to be sent by the
Smart Transmitter Interface to the field device. Many commands are device dependent. Consult the documentation provided with your field device for details about the commands supported. Set this field to a device-recognizable command before sending the packet to the Smart Transmitter Interface.

Byte Count
This one-byte field indicates the number of bytes to follow this field excluding the check byte. Valid values are 0 to 113. Insert the number of bytes required for this packet before transmitting it.
Data
This field specifies a number of data bytes associated with the command number given in the command field. Set the number of data bytes to the appropriate value for the command in question. The valid range is from
0 to 113. Only use this field when writing data to the HART device.
Check Byte
The Smart Transmitter Interface calculates the value of this field and transmits it to the field device as the last byte of a packet. The field device verifies the integrity of the received data packet by checking this byte. Since the Smart
Transmitter Interface calculates this byte, you can set this field to a null (00).

Additional HART Protocol Information C-5
Response Code
This two-byte code contains the HART field device status as sent by that device. Field devices detecting a communications error set the most significant bit, bit 7, of the first byte and identify the error in the other seven bits. If the last message was received without error, the field device will clear bit 7 and return a device-dependent response in the other seven bits.
The second byte of this response code returns the operating status of HART field devices. This byte may default to 0 when a communications error occurs as indicated by bit 7 of the first byte being set.
IMPORTANT
The host processor ignores any values in the data field when a communications error is detected.

FLEX I/O HART Modules Network Messaging
What This Appendix
Contains
Communication
This appendix discusses:
• How to communicate with the FLEX I/O HART modules via the MSG or CIO instruction
• The differences between Attributes and Assembly Indexes
• Enhancements to the HART frame
The messaging between the processor and the HART I/O module is handled via MSG or CIO instructions, depending on the processor type. These ladder logic instructions need specific details for proper operation. In particular, they need four items:
• Class
The Class value for FLEX is 7D hex.
• Instance
The Instance is a number between 1 and 8. This number indicates the module location relative to the adapter module. Use 1 for the module connected directly to the adapter.
• Service
The Service value is 0E hex for Get Attribute Single and 10 hex for Set
Attribute Single. Use a Service value of 0E hex to read data from the adapter and 10 hex to write data to the adapter.
• Attribute
The Attribute value is based on the Attribute Values table.

FLEX I/O HART Modules Network Messaging D-3
Differences Between
Attributes and Assembly
Indexes
The two Host Access Groups on the module let two different hosts communicate at the same time to the module and its associated field devices.
The Attribute used by MSG or CIO instructions send the attribute number to the adapter module. The I/O modules use Assemblies. The adapter cross-references the requested Attribute to the corresponding Assembly and forwards it to the associated FLEX I/O HART module for processing.
Messages are sent and received through the multiple HART
Request/Response buffers in the same Host Access Groups. To maximize data throughput, these buffers are different sizes.
EXAMPLE
If a message from the module was expected to have 23 bytes, the message would fit into Attributes 6B…70 hex for Host
Access Group 1. Therefore, the response could be obtained by reading any of these attributes.
If you read the Attribute, 100 bytes would be returned containing 23 expected bytes and 77 zero-filled bytes. Sending these extra 77 bytes takes additional time and slows down the response time. Therefore, use the Attribute that best fits the expected message size.
If you attempt to get the response from Attribute 74 hex, an error message would be reported. All messages containing HART commands and responses to and from the FLEX I/O modules are enhanced while standard HART messages are used between the I/O module and the field device. The Error message is an example of these enhancements.
Table D.2 Standard HART Message
Preamble Start

Count
(Respons e Code)
Data Checksu m
The Preamble syncs the field devices to the I/O module. Once the HART message is received in the I/O module, the Preamble is no longer needed. The
FLEX I/O HART modules can queue up to four HART commands, meaning that the module needs a method to identify the HART response to the associated command.

• Cold Start
Cold Start indicates that the HART I/O module has made a cold start and the bit is reset when it was first read.
HART Frame Enhancements
Attribute 69 hex for Host Access Group 1 contains only six bytes. Since every
HART response starts with these six status bytes, this attribute only contains this information. In addition, you need to account for these six status bytes when selecting the associated response Attribute. Add six bytes to the size of the HART response to accommodate the status bytes.
If you do not know the size of the expected response from the HART module, read Attribute 69 hex for Host Access Group 1. The returned data indicates which Assembly Index contains the response. Once you get this index, issue a
MSG or CIO to the associated Attribute. For example, if the Assembly Index is 14, issue a MSG or CIO to Attribute 6D hex.
The Response Error field indicates if the response is available. Once a HART command is issued, it takes a small amount of time to send the message via
HART protocol to the field devices, time for the field device to interpret the command, and time to send the response back to the FLEX I/O HART module. During this time, you could request the response prior to the module obtaining it from the field device. In this case, a Response Not Available response is returned in the Response Error field. The module assumes another request will gather the response.

Appendix
E
Configure the 1794-IE8H Module in RSLogix
5000 Software Over the ControlNet Network
What This Appendix
Contains
This appendix provides the information needed to configure the 1794-IE8H analog input module in RSLogix 5000 software over the ControlNet network using version 13 or earlier and the generic profile.
Background Information
Make sure that your Comm-Format is set to Input Data - INT so that you can set the output size to 0. In the FLEX generic profile, you need these sizes:
• Input - 8
• Output - 0
• Config - 2
• Status - 5
IMPORTANT
HART commands will only work when the Data Format control is configured for a 4 to 20 mA range. The default configuration when using the generic profile is 0, which configures the module for a 0 to 20 mA range. The filter cutoff defaults to 0 as well, which is invalid. The filter cutoff must be set to a valid value for the module to operate in any mode.
Adapter Name is what you named the ControlNet adapter when it was originally created.
Slot is the position of the FLEX module in the rack, starting with zero.

Appendix
F
Configure the 1794-OE8H Module in
RSLogix5000 Software Over the ControlNet
Network
What This Appendix
Contains
This appendix provides the information needed to configure the 1794-OE8H analog output module in RSLogix 5000 software over the ControlNet network using version 13 or earlier and the generic profile.
Background Information
Make sure that your Comm-Format is set to Data - INT. In the FLEX generic profile, you need these sizes:
• Input - 0
• Output - 9
• Config - 11
• Status - 4
IMPORTANT
HART commands will only work when the Data Format control is configured for a 4 to 20 mA range. The default configuration when using the generic profile is 0, which configures the module for a 0 to 20 mA range.
Adapter Name is what you named the ControlNet adapter when it was originally created.
Slot is the position of the FLEX module in the rack, starting with zero.
