Channel %1 action %2<ALNX> not possible due to ASUP
%1 = Channel ID
%2 = Action number/action name
The action in the 2nd parameter was rejected, since an asynchronous subprogram is currently active.
Currently, only the integrated search run is rejected with this alarm. The integrated search run is activated, if search run is triggered in the Stop program state. In other words: Parts of a program have already been executed and a following program part is "skipped" with search run in order to continue the program afterwards.
The event is not possible if the program is stopped within an asynchronous subprogram or if an asynchronous subprogram had been selected before the event. An asynchronous subprogram is selected, when the triggering asynchronous subprogram event arrives, but the asynchronous subprogram cannot be started (e.g. the asynchronous start program is not started because of a read-in disable or because the Stop key is active).
In this case, it is irrelevant whether a user ASUP or a system ASUP has been triggered. User ASUPs are activated via FC-9 or via the fast inputs.
The following events lead to system ASUPS:
Mode change Overstore on
Aborting subprogram level
Switching on of single block, type 2
Setting machine data effective
Setting user data effective
Change skip levels
Dry run on/off
Program test off
Correction block alarms
Editing modi in Teach
External zero offset
- Alarm display.
Repeat the action after the end of the asynchronous subprogram.
Clear alarm with the Delete key or NC START.
