I am facing this problem on a four cylinder hydraulic press. The PLC input/output are not responding. Suggestions/Help required.
what you mean by I/O not responding..any led blinking red/yellow...any alarms annuciated on hmi..Plc SOFTWARE Interface
The problem was the PLC was not reading any inputs. I tried to reset the PLC but the red LED was continuously on, so I understand this is a program faultwhat you mean by I/O not responding..any led blinking red/yellow...any alarms annuciated on hmi..Plc SOFTWARE Interface
Now the Red LED is on after I reset the PLC.OK
so you have a program fault are you referring to OEM manual ...
We dont see red LED on the screenshot ...
