Global bits
The bit field serves as collective display of global notifications. Errors can either occur at the
FMU itself or at the slaves. To distinguish between the different errors, the variable part
ErrRemAddr contains the error location (address = MAC ID), while the variable part ErrEvent
lists the corresponding error number. If more than one error is detected, the error location will
always show the device with the lowest MAC ID.
Bit:
0 7 6 5 4 3 2 1
Bit Explanation
0
Control error . Parameterization error.
1
Auto-clear error . FMU stopped communication to all slaves and reached the auto-clear end state.
2
Non-exchange error . At least one slave has not reached the data exchange state, hence no process
data can be exchanged.
3
Fatal error . Due to severe bus error, no further bus communication is possible.
4
Event error . The FMU has detected bus short circuits. The number of detected events are fixed in the
BusErrorCnt variable. The bit is set when the first event is detected.
5
Host not ready notification . If the bit is set, the host program ist NOT ready to communicate.
6
Duplicate MAC ID detected . The FMU has detected another device in the network with the same
MAC ID.
7
Duplicate MAC ID check in progress . As long this bit is set, the FMU is checking for duplicate MAC
IDs.
Errors
The following error numbers are valid for the error event if "Error remote address" is 255.
