    Operating Environment Precautions • Emergency stop circuits, interlock circuits, limit circuits, and similar safety measures must be provided in external control circuits. • The PLC will turn OFF all outputs when its self-diagnosis function detects any error or when a severe failure alarm (FALS) instruction is executed. As a countermeasure for such errors, external safety measures must be provided to ensure safety in the system.
