hey guys I've been having an issue with my HMI not communicating with the PLC. The PLC is a CompactLogix L32E and It happens at random times.
when i go to the site i see the "MS" and "NS" lights on the PLC flashing red
I have a managed switch inside my PLC cabinet and to correct this all i have to do is reboot the managed switch then the computer will start communicating with the PLC again. I have to do this several times a day.
I have replaced the managed switch in the PLC cabinet with a new switch.
I have read were someone had to re-flash the PLC controller to correct the issue.
have any of you guys had this similar issue?
thanks
