4.4.2. Example for saving numerous errors of the same class
Only one error can be memorized and detailed in the internal diagnosis on the 40 and 50
series central units. An automatic programmed acknowledgment enables reading other
eventual errors. An adapted program enables saving them when necessary.
The program in this case is applied to class 4 errors but may also be applied to class 3 errors.
In the present case the last three errors are only saved if the occurred error is different to the
previous.
The
M 255.14
bit signals the error presence. At that moment, if the
M 000.00
status is 1 then
the error is acknowledged due to the CS31QU block.
