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:

Table 65: Structure Head for the Diagnostic Data

Byte
Data type
offset
0 / 1 WORD
2 / 3 WORD
4 / 5 BYTE
BYTE
6 / 7
DWORD
8 / 9
The "API" process type has a data length of 4 bytes. Depending on the version of
the data set, the diagnostic data follows at byte offset 6 (version 1.0) or byte offset
10 (version 1.1).
The description of the diagnostic data in the subsections, depending on the
"BlockType", begins back with byte offset 0.

More information on extended channel diagnostics is available in the appendix in
the section "Channel-Specific Diagnostics".
