Hi guys,
This my first time posting hope I get help in my issue..
I have Allen bradley control logix safety PLC (1756-L61S) connected with several remote I/O via ethernet card 1734-AENT, these I/O mainly emergency switch and limite switchs. But time to time (daily once or twice) some input or output card get disconnected randomly each time in different I/O rack for 2 seconds and get connected back again but it causing emergency switch active and interrupting machine processes.
When its occurred no minor/major alarm is registered and the cards get disconnected charging from rack every times it happens.
We replace the ethernet card(1756-EN2T) in local rack still same.
Hope I get support as the problem get appeared more frequently.
