What it means
Power restored on the DeviceNet network: "The DeviceNet network has recovered its 24 V supply."
What to check
- Recovery message: it closes the episode opened by 71299 and gives its exact duration.
- Measure this duration — a few seconds points to a protection device that resets itself, several minutes to human intervention.
- After recovery, check that the I/O units have actually reappeared and that the zone signals are re-armed.
- Note: Its value lies in the timing: in the field log, 71299 at 08:47:55 and 71412 at 08:47:57, i.e. a 2-second outage — too short for human action, the signature of a transient electrical fault.
