Overview of Alarms
NCK alarms
15110 [Channel %1: ] Block %2 REORG not possible
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: In order to synchronize the preprocessing run and the main run with REORG, the control accesses
modification data which are maintained in a logfile. The alarm indicates that no more capacity is avail-
able in the logfile for the specified block in the channel.
The alarm message means that the logfile has been deleted in order to obtain additional memory for
program reorganization. Consequently, it is no longer possible to REORG the preprocessing memory
up to the next coincidence point.
Reaction: Alarm display.
Remedy: Please inform the authorized personnel/service department. No remedial measures are available for
the further execution of the current part program, however:
1. Reduce log file size requirement by:
Reducing the distance between the preprocessing and the main run via appropriate preprocessing
stops (STOPRE).
2. Increase the size of the logfile by means of the channel-specific machine data:
Modify MD28000 $MC_MM_REORG_LOG_FILE_MEM and
Modify MD MD28010 $MC_MM_NUM_REORG_LUD_MODULES
Program Con- Alarm display showing cause of alarm disappears. No further operator action necessary.
tinuation:
15120 If a power failure occurs now, the last data changed will be lost;
index/buffer size = %1
Parameters: %1 = Index/buffer size
Definitions: Notification alarm. The alarm has no negative impact on the current machining.
One of the system-internal data buffers, in which the last changed, buffered data are stored,
has overflowed because the current data change rate is too high.
The alarm warns that a spontaneous power failure in this situation
(mains fault, disconnect the system from the power supply) would
cause a loss of the immediately previously changed buffered data
(tool data, parts programs, R parameters, GUDs,...)
If the system is operated in an environment in which a power failure cannot occur, then the output of
this alarm can be prevented via machine data MD18232 $MN_MM_ACTFILESYS_LOG_FILE_MEM[
index ] = 0.
For information, parameter %1
specifies the index of the machine data,
and the buffer size set there.
Reaction: Alarm display.
Remedy: If the alarm is present only sporadically, it can simply be regarded as a notification.
The regular control behavior is not affected.
If one does not want to or cannot eliminate the cause, then the alarm can be suppressed by setting
MD11415 $MN_SUPPRESS_ALARM_MASK_2; Bit3=1 ('H8').
If the alarm is permanently present, please inform the authorized personnel/service department.
The value of MD18232 $MN_MM_ACTFILESYS_LOG_FILE_MEM[ index ] will then have to be
increased.
Program Con- Alarm display showing cause of alarm disappears. No further operator action necessary.
tinuation:
