Group Field Power Health

Direction: input to application from controller
Type: boolean
Values:

TRUE = all field power supplies for all active digital output modules in the group

are within the range 18V to 32V dc inclusive

FALSE = one or more field power supplies to an active module is less than 18V dc

or greater than 32V dc.

Description:

Provides a top level indication of the health of field power supplies to active digital
output modules.

Note: The controller incorporates a 0.5V hysteresis on these thresholds to prevent

chatter. The controller will declare a fault when a supply falls below 18V, but will not

clear the fault until the supply rises to 18.5V. Similarly the controller will declare a fault
when a supply exceeds 32V, but will not clear the fault until the supply falls below
31.5V.




Field Power Status Integers

The variables in the rack of field power status integers (all DINT) provide information

to the application about the field power supplies to a group of digital output modules.

Group Field Power Current

Direction: input to application from controller
Type: DINT
Values:

0 to 8,000mA or greater (limited by capacity of DINT variable)

Description:
Reports the total current that all the active digital output modules in a group are
drawing from the field power supply. Accuracy is

10%.
