In the alarm situation, this asynchronous subprogram could not yet be activated; that is
why the action (normally start of part program) must be rejected.
Reasons for the fact that the asynchronous subprogram could not be triggered:
1. The asynchronous subprogram does not exist
(/_N_CMA_DIR/_N_PROG_EVENT_SPF)
2. The asynchronous subprogram is allowed to start in the referenced state only (see
$MN_ASUP_START_MASK)
3. READY is missing (because of alarm)
Reactions: - Alarm display.
Remedy: • Load program
• Check $MN_ASUP_START_MASK
• Acknowledge alarm
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
16942
Channel %1 start program command action %2<ALNX> not possible
Parameters: %1 = Channel ID
%2 = Action number/action name
Definitions: Currently, the alarm occurs only in combination with the SERUPRO action. SERUPRO
stands for search via program test.
SERUPRO is currently searching the search target and has therefore switched this chan-
nel to the program test mode. With the START program command in channel 1, another
channel 2 would actually be started, which means that axes would really be started during
the search action.
If this alarm is switched off (see help), the user can make use of the above behavior by
initially selecting via PLC the program test mode in channel 2, leaving channel 2 execut-
ing until its natural end, stopping channel 2 in order to deselect program test again.
Reactions: - NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Remedy: Alarm can be switched off with $MN_SERUPRO_MASK bit 1.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
16943
Channel %1 action %2<ALNX> not possible due to ASUP
Parameters: %1 = Channel ID
%2 = Action number/action name
Definitions: The action in the 2nd parameter was rejected, since an asynchronous subprogram is cur-
rently 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:
