Receive message
overflow MoreInformation ARRAY [1] of WORD.
Number of receive message overflows indicated from
the CAN chip.
Global bits
The bit field serves as collective display of global notifications. Errors can either occur at the
FMU itself or at the nodes. To distinguish between the different errors, the variable part
ErrRemAddr contains the error location (address), while the variable part ErrEvent lists the
corresponding error number. If more than one error is determined, the error location will always
show the lowest faulty bus address.

Bit Explanation
0
Control error . Parameterization error.
1
Auto-clear error . FMU stopped communication to all nodes and reached the auto-clear end state.
2
Non-exchange error . At least one node has not reached the data exchange state, hence no process
data can be exchanged.
3
Fatal error . Due to severe internal error, no further bus communication is possible.
4
Event error . The FMU has detected transmission errors. 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
Timeout error . The FMU has detected an overstepped timeout supervision time of at least one CAN
message to be sent. The transmission of this message was aborted. The data is lost. It indicated that
no other CAN device was connected or could not acknowledge the message sent. The number of
timeouts detected are stored in the message timeout variable. The bit is set when the first timeout is
detected.
7
Reserved.
Errors
The following error numbers are valid for the error event if "Error remote address" is 255.
