Diagnostic counters

The IEC 60870-5-103 protocol diagnostic counters can be viewed via LHMI path
Monitoring/Communication/IEC 60870-5-103/Serial. Counters related to IEC
60870-5-103 link instances 1 and 2 have the suffixes (n) 1 and 2. The diagnostic
counters show complete IEC 60870-5-103 link frames and link errors. The serial
drivers (COMn) have their own diagnostic counters for lower level serial
communication errors. COMn counters are count all messages on the serial line. It
is possible to reset the diagnostic counters by setting the Status value to "True".
When an IEC 60870-5-103 instance has not been taken in use, the diagnostic
counters belonging to the instance contain value -1. Counter value 0 in turn means
that the instance is in use, but no messages have been detected.
