About the Modules        5
• Low and high clamps can be set individually or on a channel basis.  When 
the output value reaches clamp value, a status bit is set, indicating the 
output is clamped. 
• Disable alarms - disables all channel alarms and faults so they are not 
reported in the channel status field.
• Fault and Idle mode action let you select what happens to the output if 
a fault occurs or if the module is in idle mode.  The choices are the 
following:
– Hold Last State
– Low Clamp
– High Clamp
– User-defined value
