Before a job execution is completed, the converter will supply the
response of the last job. Thus, the master must always check whether the
received response corresponds to the transmitted job.
For plausibility check, the value in the response identification (RID),
the received parameter number (PNU) with the corresponding index
(IND) and the current parameter value (PV) for writing of parameters
can be used.
Error messages in case of non-executable jobs
If the response identification is "Job cannot be executed" (RID = 7), the
parameter value (
PV2) of the converter response is additionally extended
by an error message. See the following table for the significance of the
transmitted values.
No. Statement
0 Invalid parameter number
1 Parameter value not alterable
2 Lower or upper value limit exceeded
3 Faulty sub-index
4 No array
5 Impermissible data type
6 Can only be reset (only 0 may be written)
7 Write element not alterable
9 Write data does not exist
201 Invalid job element in the job received last
202 Internal response ID cannot be mirrored

Fig. 15-26: PID structure
The structure and function of the parameter index (IND) depend upon the
type of parameter to be transmitted.
With parameter record-dependent values, the parameter record can be
selected via bits 8 and 9 of the indices (IND) (0 = parameter record 1, 1 =
parameter record 2, ….).
