Switching to auto mode
When switching to auto mode, all STATIC and SEMISTATIC tasks will be deselected from
the tasks panel. The stopped STATIC and SEMISTATIC tasks will start next time any of the
START, FWD or BWD button are pressed. These tasks will then run continuously forward
and not be stopped by the STOP button or emergency stop.
What happens with NORMAL tasks that has been deselected in the tasks panel depends on
the system parameter Reset in type Auto Condition Reset in topic Controller. If Reset is set to
Yes, all NORMAL tasks will be selected in the tasks panel and be started with the START
button. If Reset is set to No, only those NORMAL tasks selected in tasks panel will be started
by the START button.
NOTE!
Note that changing the value of the system parameter Reset will affect all the debug resettings
(e.g. speed override and simulated I/O). For more information, see Technical reference
manual - System parameters, section Auto Condition Reset.
Restarting the controller
If the controller is restarted, all NORMAL tasks will keep their status while all STATIC and
SEMISTATIC tasks will be deselected from the tasks panel. As the controller starts up all
STATIC and SEMISTATIC tasks will be started and then run continuously.
Deselect task in synchronized mode
If a task is in a synchronized mode, i.e. program pointer between
SyncMoveOn and
SyncMoveOff, the task can be deselected but not reselected. The task cannot be selected until
the synchronization is terminated. If the execution continues, the synchronization will
eventually be terminated for the other tasks, but not for the deselected task. The
synchronization can be terminated for this task by moving the program pointer to main or to
a routine.
If the system parameter Reset is set to Yes, any attempt to change to Auto mode will fail while
a deselected task is in synchronized mode. Changing to Auto mode should make all
NORMAL tasks selected, and when this is not possible it is not possible to change to Auto
mode.
