16941 Channel %1 action %2<ALNX> rejected because no program event has
been executed yet
Parameters: %1 = Channel ID
%2 = Action number/action name
Definitions: The setting of the machine data $MC_PROG_EVENT_MASK forces an asynchronous subprogram to
be triggered automatically on RESET or PowerOn. The implicitly triggered asynchronous
subprograms are normally called "Event-triggered program call" or "Program event".
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)
Reaction: Alarm display.
Remedy: - Load program
- Check $MN_ASUP_START_MASK
- Acknowledge alarm
Program Clear alarm with the Delete key or NC START.
Continuation:
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 channel 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 executing until its natural
end, stopping channel 2 in order to deselect program test again.
Reaction: 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 Clear alarm with the RESET key. Restart part program
