programming software, see the software user manual.
Selecting a 1797-IE8 or
-IE8NF FLEX Ex Analog
Input Module’s Operating
Features All features of the 1797-IE8 and -IE8NF analog input modules are
independently configurable in two four-channel groups (channel 0-3 &
channel 4-7).
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 Remote and Local Fault alarms, see page 1-5.
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.
