Many automation failures are not caused by the PLC logic itself.

In real industrial plants, Industrial PLC programming becomes difficult when problems appear between field devices, communication networks, grounding systems, and HMI/SCADA integration.

Common causes of PLC faults include: • Incorrect I/O mapping • Communication failures • Grounding issues • Unstable field signals • Poor diagnostics

Before modifying the program, always verify the real field condition first.
