Diagnosis Data Sets

The diagnostic information of the fieldbus coupler (IO device) can be read
acyclically using standard diagnosis data sets (records). The structure of the data
sets is defined in the PROFINET IO specification.
More details are available in the specification under "IODReadReq" or
"IODReadRes".
The data set number (index) makes it possible to distinguish between the
diagnostics level (device, module, submodule or channel error) and the
diagnostics structures.
The list of diagnosis data sets listed below provides the respective message
structures in the case of pending diagnostics.

Structure of the Standardized Diagnosis Data Sets

The diagnosis data sets consist of several structure elements. The first element in
the data set is the head of the structure. It describes the version and the length of
the following data. An identifier (BlockType) specifies the structure of the
diagnosis data.
The identifiers listed below are currently used by the fieldbus coupler:
•
0x0010: Channel diagnostics
•
0x8104: Difference between expected/real configuration
The version enables you to see if the process type (Application Process Identifier
– API) follows immediately after the head structure or not:
•
Version 1.0: Data set does not contain the API
•
Version 1.1: Data set contains the API
The head of the structure has a length of 6 bytes for the description of the version
and length of the following data and is structured as follows:
Description
32778
Standardized channel diagnostics of a submodule slot
32779
(subslot specific)
32780
49162
Channel diagnostics of a slot (slot specific); currently
49163 identical with the data set number 800A, as only one
submodule can exist for each module.
49164
Deviations in the specified and actual configuration of the
57346
submodules assigned to the IO controller (IOAR).
57354
Channel diagnostics of all signal channels allocated to a
57355 connection (AR), contains all channel diagnostics structures
of the submodule slots.
