Description:
Depth of the memory optimization in the PowerFail log file (=search depth, to
find out
whether a parameter to be written is already included in the PowerFail log
file).
It is possible to increase the value of the machine data if
alarm 15120 occurs during program processing and if you wish to avoid it.
(Alternatively, you can increase the size of the PowerFail log file itself
by means of MD18232 $MN_MM_ACTFILESYS_LOG_FILE_MEM, if you have the necessary
access right
and if the required memory is available.
Value
0 = same effect as value 1.
Writing of a variable value is therefore very time-efficient at the
cost of the required memory.
0< n <= Maximum value
= Writing of a new variable value leads, prior to saving of the new
variable value in the PowerFail log file, to the last n write
operations which have been being checked to see whether
the new parameter to be written has already been written once.
If yes, the new value is not entered again in the PowerFail log
file, but the old value is overwritten with the new one.
If no, the new value is entered.
At the cost of the required time, writing of a variable value
can therefore be designed very memory-efficiently.
Changing of the data can shorten/increase the time requirement of the present
application.
Changing of the data can fill the available log buffers faster/more slowly.
Frequent occuring of alarm 15120 -> Increase values for index=0,1,2.
The value indicating the index to be changed can be deducted from the param-
eter of alarm 15120:
if it is the value for MD18232 $MN_MM_ACTFILESYS_LOG_FILE_MEM[0], then
increase the value for index 0;
or increase MD18232 $MN_MM_ACTFILESYS_LOG_FILE_MEM[0] itself.
Index Meaning
0 Search depth in preprocessing buffer
1 Search depth in buffer for data changes within the range of tool change
2 Search depth in buffer for data changes of main processing (especially
synchronized actions)
