Structure of the Standardized Diagnosis Data Sets

The diagnosis data sets consist of several structures.
The first element in the data set is the head of the structure. It describes the
version and the length of the following data. The "BlockType" specifies the
structure and content of the data set. The following "BlockTypes" are used by the
fieldbus coupler.

Table 162: "BlockType"

BlockType
0x0010
0x8104
Based on the version can differ if right after the head structure of the process type
(Application Process Identifier - API) follows or not.

Table 163: "Version"

Version
1.0
1.1
The head of the structure has a length of 6 bytes and is structured as follows:

Table 164: "Head of the Structure"

Byte
Data type
offset
0 / 1 WORD
2 / 3 WORD
BYTE
4/5 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 diagnostics data follow with Byteoffset 6 (Version 1.0) or
Byteoffset 10 (Version 1.1). However, the description of the diagnostics data in
the subsections, depending on the BlockType, begins back with Byteoffset 0.
