7.4.4. Read error list
The error list is requested using the “E“ (Error List) instruction.
Inquiry from the master:
0xYY 0x45 (“E“) Serial num-
ber of error
in the list 0x00, 0x00, 0x00, 0x00
1 byte 1 byte 2 bytes 4 bytes
The first error is requested with 0x00 0x00
Response of the SideStep:
0xYY 0x45 (“E“) Serial num-
ber of error
in the list Error information
1 byte 1 byte 2 bytes 4 bytes
Attention:
•
When a new error occurs, the serial numbering of the listed errors changes.
Error 0 then becomes Error 1, Error 1 becomes Error 2, etc.
• Once the error list is full, the oldest error in the list is deleted.
•
If no entry on the required number is found in the error list, an external
diagnostic error with code 0x34 is triggered. In this case the response value
is 0xFF 0xFF 0xFF 0xFF
•
With number 0 the current error can be monitored
•
If there is no error in the error list, error 0x00 0x00 0x00 0x00 is displayed
