Sinumerik Alarm 16951 Channel %1 search run in a program section that cannot be searched
Parameters:
%1 = Channel ID
Definitions:
With the language commands IPTRLOCK and IPTRUNLOCK, the part programmer can identify part program sections that cannot be searched. Every search run in these program sections will be acknowledged with alarm 16951. In other words: When the alarm appears, the user has started a search run (Serupro type) and the search target lies in an area that cannot be searched! An area that cannot be searched can also be defined implicitly with the machine data $MC_AUTO_IPTR_LOCK.
Note: The alarm can only be generated when the simulation is completed during the search run. The alarm cannot be output immediately at the start of the search run.
Reactions:
– NC Start disable in this channel.
– NC Stop on alarm.
– Alarm display.
– Interface signals are set.
– Alarm display.
Remedy:
$MN_SUPPRESS_ALARM_MASK $MC_AUTO_IPTR_LOCK and language command IPTRLOCK
Program Continuation:
Clear alarm with the RESET key. Restart part program
