If the parameterized reboot delay time is 0.0, the function is deactivated.
System variables
The time remaining until the NC is rebooted can be read in the system variable:
$AN_REBOOT_DELAY_TIME
While no request for a reboot of the NC (NC reset) has been triggered from the user interface,
the system variable has the value 0.0.
A value greater than 0.0 indicates that a reboot request (NC reset) has been triggered from
the user interface and also the time remaining in the NC or PLC until the reboot.
Application example
Evaluating the system variables in a static synchronized action
Condition part: Check for a value greater than 0.0 because then a request for a reboot of the
NC (NC reset) has been made from the user interface.
Action part: e.g. triggering "safe standstill" as part of the "Safety Integrated" function.
