5.3.1.1 GlobalBusStateField for PROFIBUS
Identifier part Identifier Explanation
Global bits GlobBit_Status Lower byte of the WORD. Details follow the table.
Status GlobBit_Status Higher byte of the WORD.
The master system can be in one of the following states:
• 16#00: OFFLINE
•
16#40: STOP
• 16#80: CLEAR
•
16#C0: OPERATE
Error remote address ErrRemAddr_ErrEvent 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.
Error event ErrRemAddr_ErrEvent Higher byte of the WORD.
Each error is assigned a number. The errors are
explained following the table.
Bus error count BusErrorCnt Counts severe bus errors, e.g. bus short circuits.
Timeout count TimeOutCount Counts the number of rejected PROFIBUS telegrams
due to severe bus errors.
Current master address MoreInformation Lower byte of ARRAY [0] of WORD.
Contains the current active master address.
Master protocol chip
online MoreInformation Higher byte of ARRAY [0] of WORD.
This variable reflects the current status of the master
protocol chip. If the value is 0, the chip is in the offline
state; if the value is 1, the chip is on the online state.
The variable is updated cyclically.
