Comparison value: With the comparison value you can specify a value which, by
comparison with the current counter content, can impact the counter output or trigger a
process alarm. The response of the comparison bit STS_COMP in the counter status or the
process alarm is to be specified via data set 80
h
for counter 0 and 82
h
for counter 1.
