Explanation
Lower byte of the WORD. Details follow the
table.

The master system can be in one of the fol-
lowing states:
16#00: OFFLINE

16#40: STOP

16#80: CLEAR

 16#C0: OPERATE
Lower byte of the WORD.
Some of the global bits indicate errors in the
network or in the FMU itself that require a
more detailed explanation. In these cases,
"ErrRemAddr" represents the source of the
error and can arise from either the FMU itself
(value = 255), or be detected and reported by
a network device. In this case, the lower byte
represents the station address. Range: 0 to
125.
Higher byte of the WORD.
Each error is assigned a number. The errors
are explained following the table.
Counts severe bus errors, e.g. bus short cir-
cuits.
Counts the number of rejected PROFIBUS tele-
grams due to severe bus errors.
