The Micrologix1500 PLC lost comms when trying to function valves from the HMI. Cycled power to the PLC, and restarted the HMI, and comms came back.
Anyone know of any known issues with the PLC dropping out unexpectedly?
The PLC is about 5 yrs old now, so I was thinking that maybe there's probs with the battery, or some sort of power supply probs...
The values being read on the HMI are passed through the DeviceNet Scanner, could there be a prob with the W/1769-SDN?
Checked cables, these were OK.
I'm new to AB's so I'm not sure where to begin diagnosing. Can RSLinx be used to help diagnose comm faults?
Cheers.
