Transmission Error: Timeout (F_WD_Time or F_WD_Time_2 Elapsed) (V2 CPU)

¿Qué significa 78 ?

A transmission error due to a timeout has occurred in an AC500 V2 non-safety CPU PM5xx system, meaning either F_WD_Time or F_WD_Time_2 has elapsed without receiving expected communication. This indicates a communication failure or an incorrectly configured watchdog timer.

• The safety watchdog timer (F_WD_Time or F_WD_Time_2) has elapsed without receiving expected communication.
• Loss of communication with a connected safety device.
• Network failure or congestion.
• The remote safety device is not sending data.
