Error response times
The error response times depend, among other things, on the logic program used and the settings of the
MultiplierDiagTestPulse
and
ModuloDiagTestPulse
parameters.
An error reaction for the tests of the I/O signals is realized by a weighted counter, therefore the switch-off
does not occur immediately at the first error of the diagnostic tests.
The maximum error reaction time results from the duration of the longest lasting test, this is the RAM test
and this is several hours.
