Selecting a 1797-IE8H FLEX
Ex Analog Input Module’s
Operating Features All features of the 1797-IE8H analog input module are independently
configurable in two four-channel groups (channels 0 to 3 & channels 4 to 7).
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.
For more information on the Remote Fault Alarm, see page 1-5. For more
information on the Local Fault Alarm, see page 1-6.
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.
IMPORTANT
The default selection value for all parameters is 0.
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.
