All processors have a RESET button on their front panel, which when pressed, causes a cold start of the PLC, in RUN or in STOP mode (starting in RUN or in STOP mode is defined at configuration), on the application contained in the memory card (or in the internal RAM)…
RESET following a fault detected by the processor
As soon as a processor detects a fault, the alarm relay on rack 0 (with TSX 57 processor) is deactivated (open contact) and the module outputs switch to fallback position or are maintained in the current state depending on the selection made in configuration. Pressing the RESET button causes the PLC, forced into STOP, to cold start.
NOTE: When the RESET button is pressed, and during the PLC cold start, the terminal link is deactivated.
