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 230: "BlockTypes"

Description
0x0010
Diagnostic data
0x8104
Real/expected configuration mismatch
The head of the structure has a length of 6 bytes and is structured as follows:

The version of the data set is 1.1. As a consequence the existing Application
process idenficator (API) is always set to zero (default API) and has a data length
of 4 bytes.
14.5.1
Extended Channel Diagnostics
The "BlockType" in the head structure corresponds to the value for a diagnostic
data set (0x0010). The length of the data set results from the following diagnostic
objects for fault submodules or channels.
The diagnostic entries are initiated by a "ExtChannelDiagnosis" structure. The
respective "ExtChannelDiagnosisData" diagnostic objects then follow for the
respective submodules or channels. The "ExtChannelDiagnosis" structure has a
size of 14 bytes and is structured as follows.
