PLC Troubleshooting
PLC troubleshooting involves identifying and fixing errors that cause the PLC to behave unpredictably. The process of troubleshooting involves converting the symptom to a desired action not occurring, which then is single out to a real world input or output. You then trace backward from real world I/O through internal conditions to be met.The following are some steps to troubleshoot a PLC:
Check the power supply and ground cabling visually.
Troubleshoot inputs and outputs to figure out why the PLC’s internal status is not in line with the external situation.
Check inputs for proper wiring.
Check outputs for proper wiring.
Identify the root cause of the problem and then take the necessary steps to fix it.
