The command is available in online mode. It resets – except for the remanent (retain, persistent) variables - the variables of the currently active application to their initialization values.
If you have initialized variables with specific values, they will be reset exactly to that value. The other variables are set at a standard initialization value (for example, integers at 0).
EcoStruxure Machine Expert asks you to confirm your decision before the variables are overwritten. The situation occurs in the event of a power outage or by turning off the controller, then on (warm restart) while the program is running.
The command has the following effects on breakpoints:
Breakpoints that were activated before resetting the active application are still activated afterwards.
Breakpoints that were deactivated before resetting the active application are still deactivated afterwards.
If the command is called during the program run is held on a breakpoint, you will be asked whether the cycle should be finished before performing the reset or if the reset shall terminate the task and perform the reset immediately. Keep in mind that not all runtime systems are able to perform a reset without finishing the cycle beforehand.
After a reset use the Start command to restart the application.
