Chapter 4 Digital I/O Operation
Field Power Status Integers
The field power status integers (all DINT) supply data to the application, about
the field power supplies to a group of digital output modules.
Group Field Power Current
Values:
•
0 to 8,000 mA 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%.
Field Power Voltage 1
Values:
• 0 to 48,000 mV or larger (limited by capacity of DINT variable)
Description:
Reports the voltage from the field power supply for the specified module and
field power input. Accuracy is
±
500 mV.
Field Power Voltage 2
Values:
• 0 to 48,000 mV or larger (limited by capacity of DINT variable)
Description:
Reports the voltage from the field power supply for the specified module and
field power input. Accuracy is
±
500 mV.
Field Fault Detection
Detection criteria differs depending on whether the output is energized or de-
energized.
Energized open circuit
Current per channel is <10 mA regardless of whether the digital output module
is on its own or in dual pair.
Energizing short circuit
When energizing, the output switch is set to flow a constant current of 2.5 A
for up to 50 ms (5 A if dual module). If the voltage across the output switch fails
to fall below 3 V within this time, then the output load is deemed to be short
circuited and the output is switched off
