What is the next step after identifying and correcting a fault in PLC troubleshooting?

The appropriate step after identifying and correcting a fault in PLC troubleshooting is to clear the fault. When a fault occurs in a Programmable Logic Controller (PLC) system, it typically activates a fault indication that needs to be addressed first—this involves identifying the root cause of the problem and making any necessary corrections to the system.

Once the fault is resolved, clearing the fault ensures that the PLC returns to its normal operating state, restoring functionality. This step is crucial for the system to resume operations and for the PLC to fully acknowledge that the issue has been resolved. Without clearing the fault code or indication, the PLC may continue to treat the system as faulty, preventing it from executing normal processes.

After this step, documenting the changes, reviewing the system, and notifying the supervisor may also be important actions, but they occur after the fault has been cleared and the system is deemed operational again.
