1. Call the following parameters to start the system function:
2. Check the return value.
3. For the state query and to check whether the system function has been completed, call
4. Check the return value:

– reqActDeactGetStateMode := REQUEST_TRUE
– nextCommand := IMMEDIATELY
– The return values 16#0000_0001, 16#0000_0002, 16#0000_0005, and 16#0000_0006
indicate that the function has been completed without errors.
– The return value 16#0000_7001 indicates that the function has been started
successfully, but has not yet been completed.
– A return value < 0 indicates that the function has been terminated with errors. You can
program error routines, depending on the return value.
these again, but with the following parameters:
– reqActDeactGetStateMode := REQUEST_FALSE
– nextCommand := IMMEDIATELY
– Return value 16#0000_7002 indicates that the function is still running.
Repeat step 3.
– A return value < 0 indicates that the function has been terminated with errors. You can
program error routines, depending on the return value.
– The return values 16#0000_0001, 6#0000_0002, 16#0000_0005, and 16#0000_0006
indicate that the function has been completed without errors.
