What does Ptxx.FieldPowerOff mean?

This boolean tag indicates that a field power loss condition exists on the channel Ptxx. A tag value of '1' signifies that the external 24V DC field power supply for the channel is not present or has failed, disrupting channel operation.

• Loss of the 24V DC field power supply connected to the module.
• Blown fuse or tripped circuit breaker in the 24V DC field power supply circuit.
• Improper or damaged wiring between the 24V DC field power supply and the module's field power terminals.
• Failure of the 24V DC field power supply unit itself.

Click steps to track your progress.

1. 1

   Verify the 24V DC field power supply connected to the module is energized and producing the correct voltage (e.g., measure 24VDC at the module's field power input terminals).

2. 2

   Check any fuses or reset any circuit breakers associated with the 24V DC field power supply circuit.

3. 3

   Inspect the field power wiring connections to the module for integrity and secure termination.
