Group Field Power Health

Provides a top level indication of the health of field power supplies to active digital output modules.
Direction
Input to the application from the controller
Type
Boolean
Values
  • TRUE
    - All field power supplies for all active digital output modules in the group are in the range of 18 V to 32 Vdc.
  • FALSE
    - One or more field power supplies to an active module is less than 18 Vdc or more than 32 Vdc.
Wiring
%IX115.9.0
IMPORTANT: The controller incorporates a 0.5 V hysteresis on these thresholds to prevent chatter. The controller declares a fault when a supply falls below 18 V but does not clear the fault until the supply rises to 18.5 V. Similarly the controller declares a fault when a supply exceeds 32 V but does not clear the fault until the supply falls below 31.5 V.
