Global BM Message Counter
The Global BM Message Counter is incremented after each monitored transfer on the
MILBus regardless of whether the transfer is errorneous or not. At RT-RT transfer, the
Global BM Message Counter is incremented by two.

Global BM Error Counter
The Global BM Error Counter is incremented after each errorneous monitored transfer on
the MILBus . If multiple errors occur at one transfer, only one error will be counted. At an
errorneous RT-RT transfer, the Global BM Error Counter is incremented by two, if at both
parts of transfer errors are detected. Otherwise, if only one part of the RT-RT transfer
includes an error, the Global BM Error Counter is incremented by one.
