Global bits
Errors
FP7 Fieldbus Master Units Technical Manual
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 correspond-
ing error number. If more than one error is detected, the error location will
always show the device with the lowest MAC ID.
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 possi-
ble.
4 Event error. The FMU has detected bus short circuits. The number of de-
tected 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 is 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.
The following error numbers are valid for the error event if "Error remote
address" is 255.

52 Unknown process data hand-
shake mode configured.
