4.3.3.10 Command 9: „Diagnosing the Safe Link "
The SaW monitors with Safe Link create a histogram of the estimated telegram
run times for each communication partner. The run times are divided into incre-
ments of 5ms between 20 and 200ms, so that the histogram consists of 36
counters.
The monitors also run counters for Safe Link telegrams presumed to have been
lost.
You can use Command 9 to read out these values and at the same time restart
the measurement.
