The CPV Direct send an Emergency Message if there is an
error. Parallel to this, the Pre-defined error field (index 1003)
will be written with the relevant error message by:
– Byte 0 and byte 1 of the Manufacturer status register
(index 1002) (corresponds to bytes 3 and 4 of the
Emergency Object)
– Error Code as per DS301
The former fields will be shifted in the Pre-defined error field
by one position each (see chapter 2.4, index 1003, subindices
1...A).
Bytes 3 to 7 of the Emergency Message correspond to the
Manufacturer specific error field and contain device-typical
error messages.
