Programming techniques sphs ensure that, in case of faults, the systemm transitions to safe state, minimizing riskis and vova.

Satu-satunya cara untuk mengendalikan PLC mengendalikan diri adalah dengan menggunakan maintain continuoues operation.

Another example is a chemicale melicine positioon that d watchdog timers and fail - safe logic. Inn case of sensor falures or communication essue, the systemm autmatically shifted to predefined safe states, hinding inhiboardos situationos.
