Global bits
Errors
28
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
(bus address), while the variable part ErrEvent lists the corresponding error
number. If more than one error is determined, the error location will al-
ways show the lowest faulty bus address.
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 is 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 Timeout error. The FMU has detected an overstepped timeout supervision
time due to rejected PROFIBUS telegrams. It indicates bus short circuits while
the master interrupts the communication. The number of detected timeouts
are fixed in the TimeOutCount variable. The bit is set when the first timeout is
detected.
7 Reserved.
The following error numbers are valid for the error event if "Error remote
address" is 255.
