16956 Channel %1 program %2 cannot be started due to global start disable.
Parameters: %1 = Channel ID
%2 = String (path with program name)
Definitions: The program selected in this channel cannot be started as "Global start disable" had been set.
Note:
PI "_N_STRTLK" sets the "Global start disable" and PI "_N_STRTUL"
deletes the "Global start disable".
The alarm is switched on with $MN_ENABLE_ALARM_MASK bit 6.
Reaction: Alarm display.
Remedy: Delete the "Global start disable" and restart.
Program Clear alarm with the Delete key or NC START.
Continuation:
16957 Channel %1 Stop-Delay area is suppressed
Parameters: %1 = Channel ID
Definitions: The program area (Stop-Delay area), which is put into brackets through DELAYFSTON and
DELAYFSTOF, could not be activated. Every stop therefore becomes effective immediately
and is not delayed!
This occurs every time, when braking into a stop Stop-Delay area, i.e. a braking process
starts before the Stop-Delay area and ends not earlier than in the Stop-Delay area.
If the Stop-Delay area is entered with override 0, the Stop-Delay area
can also not be activated (example: a G4 before the Stop-Delay area allows the user
to reduce the override to 0 and the next block in the Stop-Delay area
then starts with override 0 and the alarm situation described occurs.)
$MN_ENABLE_ALARM_MASK Bit-7 switches on this alarm.
Reaction: Interface signals are set.
Alarm display.
Remedy: $MN_STOP_MODE_MASK and language command DELAYFSTON DELAYFSTOF
Program Alarm display showing cause of alarm disappears. No further operator action necessary.
Continuation:
16959 Channel %1 action %2<ALNX> prohibited during simulation block
search.
Parameters: %1 = Channel number
%2 = Action number/action name
Definitions: The function (2nd parameter) must not be activated during simulation search.
Reaction: Alarm display.
Remedy: Wait for search end.
Program Clear alarm with the Delete key or NC START.
