How to determine the cause of the last stop condition
Product Line:
TSX57xx, Unity, PL7
Resolution:
- %SW58: the most significant byte contains the day of the week (1 for Monday through to 7 for Sunday), and the least significant byte contains the code for the last stop:
- 1 = change from RUN to STOP by the terminal or the dedicated input.
- 2 = stop by watchdog (PLC task or SFC overrun).
- 4 = power outage or memory card lock operation.
- 5 = stop on hardware fault.
- 6 = stop on software fault. Details on the type of software fault are stored in %SW125.
