Bus Errors E0 - EA
In general, the display indicates the error segment and
position in the event of a bus error.
Error codes 0BE0 hex to 0BEA hex are assigned to bus errors
where the error location or area cannot clearly be defined.
The controller board display only shows the last two
characters, i.e., E0 hex to EA hex .
The error codes are described on page 49 and
onwards.

outputs are reset in the LOOK FOR FAIL state. They remain
reset until the bus is restarted and data cycles are transmitted
without errors.

information is read from the diagnostic parameter
registers with the "Read_Value" service, the error
code is mapped to the diagnostic parameter register,
and the value 0000 hex is mapped to the extended
diagnostic parameter register.
