Enable Automatic Shut Down:
If this switch is selected, then TwinCAT is stopped after an adjustable retention time, and "Windows XPe" is shut
down. Device 1 (here the CX1100) is switched off after the retention time has elapsed. Even when the power fails for
very short periods (<<10s) the system shuts down and the CX is switched off.
