Hi, folks, how’s going?
On our one production line, we use AB logix5000 as master PLC and Fanuc robs as slaves.
But today the outputs from one rob to the master PLC keep being on and off (should be always on). So we tried to fix it.
From rob side, the indicator of Controlnet module is red and one of alarms is PRIO-156 CNET Er 0002 Bd…
From Logix5000, we can see there are ControlNet faults with code 16#0022 and 16#0203, and the status of rob Controlnet keep doing “IO faulted, waiting, connecting, shutting down, standby, IO faulted, waiting…”
We checked the rob I/O connection, it was dirty and loose. We cleaned and tied it up. But still the same issue.
Could somebody give us a help to figure it out?
Thanx a lot.
