PLC Troubleshooting Techniques | Ladder Logic Fault Traps & Time Stamp Tutorial
PLC Programming is one of the most important skills of an automation engineer and technician. The most basic way to trap an occurrence of an event is through a counter instruction which we’ve covered in the past. However, effective PLC troubleshooting may need to involve additional logic that would add a timestamp to the occurrence of the event. By doing so, the PLC programmer will know when a certain event has occurred and is able to raise other questions as needed.
