13.6.3.1 Explanation of history ma-
nagement
The control stores 10 sets of error messages
on a rolling basis. Once there are 10 records,
the oldest record is overwritten by a current
entry. An error message set consists of the
following entries:
1. Date of error message
2. Contents of error message
3. Frequency of error message
4. Error origin
If an identical error occurs several times in a
row, the first entry relating to this error is
updated with the date of the most recent
occurrence and the frequency is incre-
mented. A new error message set is not
recorded.
The situation is different if a particular error
occurs multiple times, but not in direct suc-
cession. In this case, a new error message
set is written for each instance.
The table below shows the layout of the his-
tory management.
