Chapter 1 About the FLEX I/O HART Analog Module Overview This chapter describes the FLEX I/O Highway Addressable Remote Transducer (HART) analog modules and what you must know and do before you begin to use them. Read this chapter to familiarize yourself with the HART analog modules.
2 About the FLEX I/O HART Analog Module • multiple data ranges that can be independently programmed for each channel. • lead breakage detection. • overrange/underrange alarms. • remote transmitter alarm. Communicate with Programmable Controllers Data connections are established between the FLEX I/O module and an Allen-Bradley programmable controller (PLC) to transfer information between the two at a scheduled rate.
About the FLEX I/O HART Analog Module Physical Features of Your Module 3 The module label identifies the keyswitch position, wiring and module type. Use the removable label to note individual designations per your application. Indicators Indicators are provided to identify input or output fault conditions, and to show when power is applied to the module. For example, the 1794-IF8IH module is shown below.
4 About the FLEX I/O HART Analog Module Data Format Alarm Example In this example, the normal active data range is 4…20 mA. The alarms are generated in three overlapping bands. Physical Input Signal Ranges 0 mA 4 mA 20 mA Underrange Remote Fault Overrange Remote Fault Local Fault Local Fault -25.00% -12.50% Programmable in 20 0.1 mA steps by Error Level 0.1 mA Steps parameter 22 mA 0.00% 100.00% Programmable in 20 0.1 mA steps by Error Level 0.1 mA Steps parameter 112.
About the FLEX I/O HART Analog Module 5 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 Fault Enable bit allows the 1794-IF8IH module to work with transmitters like the one just described. IMPORTANT Once the alarm is issued, it remains active as long as the input signal value remains above the programmed value.
6 About the FLEX I/O HART Analog Module 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.

42 1794-IF8IH and 1794-OF8IH Configuration Data Formats and Error Ranges 44780 Remote High High Alarm Limit (8 of 16 bit) Sets the limit for the Remote Fault High High Alarm in 1 μA steps. This affects Data Formats 0…7. Steps apply to the 4…20 mA range and 0…20 mA range. For example, a value of 20400 will cause a Remote Fault High High Alarm above 20.4 mA (20400*1 μA = 20.4 mA).
1794-IF8IH and 1794-OF8IH Configuration 43 High Alarm Limit (8 of 16 Bit) Sets the limit for the High Alarm in 1 μA steps. This affects Data Formats 0…7. Steps apply to the 4-20 mA range and 0…20 mA range. For example, a value of 20000 will cause an High Alarm above 20.0 mA (20000*1 μA = 20 mA).
44 1794-IF8IH and 1794-OF8IH Configuration This does not disable the module from gathering HART Command 3 information from the HART Field device. As such, HART Command 3 information from the HART Field device is still available via an unconnected message to the module. When the adapter powers up, it reads each module to find out which modules are present in the Flexbus.

46 1794-IF8IH and 1794-OF8IH Configuration Real Time Data (RTD) Profile, Primary Status Parameters Alarms This module is capable of generating four different alarms; low, high, remote and loop alarm. The diagram below graphically shows at what values these alarms are generated for Data Format 5. Alarm Operation In this example the normal active data range is 4…20 mA. The alarms will be generated in three overlapping bands.
1794-IF8IH and 1794-OF8IH Configuration 47 is meant to be used as a Low Low Alarm, set from 3.999 mA to 2 mA (for this data format this is -0.0063% to -12.50% of range), as an example. If the input continues to fall the Loop Alarm is issued at 2 mA (-12.50%). Again, as with the Low Alarm and Remote Alarm, when the Loop Alarm is issued, it stays active at any value below 2 mA (-12.50% of range).
48 1794-IF8IH and 1794-OF8IH Configuration Formats 8…15, with pre-programmed fault levels, see Data Formats and Error Ranges on page 42. The Low Alarm is active for Data Formats 0…7, unless disabled by a "0" (default) value of Low Alarm Limit. The Low Alarm is not available for Data Formats 8…11, since the normal input range includes 0 mA. The Low Alarm is always active for Data Formats 12…15, with pre-programmed fault levels, see Data Formats and Error Ranges on page 42.
1794-IF8IH and 1794-OF8IH Configuration 49 Remote Alarm (8 of 1 bit each) Alarm from remote transmitter, indicating transmitter difficulties, sensor difficulties or loop to the sensor is open. If no transmitter is present this alarm can be utilized as a Low Low and/or High High Alarm. This is accomplished programmatically by "ANDing" together the Remote Alarm and the Low Alarm for a Low Low Alarm and the Remote Alarm and the High Alarm for a High High Alarm.

52 1794-IF8IH and 1794-OF8IH Configuration The I/O module performs automatic retries and therefore a user should rarely recognize communication problems at the protocol layer. Therefore, this flag can be used to qualify the communication quality.

1794-IF8IH and 1794-OF8IH Configuration 67 Latch Mode (8 of 1 bit each) Latch Mode determines channel operation under wire off/lead break fault conditions. Channel fault detection occurs on a continuous basis. If a fault is detected, the channel fault alarm is set (if Fault Mode is enabled). If latch is ON the fault is latched until a Global Reset is issued at which time the fault is reset. If latch is OFF the channel reports the fault until the fault is corrected. Upon correction the fault is reset.

Chapter 6 Configure Module Messaging Overview Read this chapter to learn how to: • configure the module to collect HART data from HART field devices. • use MSG Instructions to access additional HART data that is cached within the module • use MSG Instructions to send a HART message directly to the HART device using the HART Pass-through mechanism of the module.
78 Configure Module Messaging HART Configuration Quick Start To get your module started with HART features, follow these quick set up procedures. Pick HART Input Data Format To set the module to collect data from your HART instrument and place it in the Input Tag, choose the Comm Format "Input Data and HART PV" when adding the module to your I/O Configuration. If you choose "Input Data", you can access HART data via Pass through messages, but it is not included in the module's Input Tag data.
Configure Module Messaging 79 Enable Publishing HART Command 3 Variables In the module configuration tag "ChXHARTCmd3Disable", make sure the value is "0" for each channel that is connected to a HART device. IMPORTANT If you previously selected "Input Data" for the Comm Format because you are not using the HART Variables in your control system then set all channels of the "ChXHARTCmd3Disable" configuration tag to "1" for the best pass through messaging and Asset Management Software performance.
80 Configure Module Messaging Select the Attribute Value for the Operation You Want to Perform CIP message attribute values of 0x74…0x86 are used for HART pass through messages, values 0x87…0xA6 are used to retrieve additional HART data from the modules internal database, and attribute 0xA7 is used to reset the Secondary Input table flag, HART Update, which is bit 5 of the loop status.
