Deviating set / actual configuration
The version enables you to see if the process type (Application Process
Identifier – API) follows immediately after the head structure or not.

The process type API 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 sub-chapters - depending on the
BlockType
- begins back with
Byteoffset 0.

Channel Specific Diagnostics
Errors occurring when configuring and setting the parameters of the station
(I/O device) and the connected I/O modules as well as external errors from the
connected periphery are reported by the coupler via channel specific
diagnostics. External errors reported by the subassemblies (e.g. short circuits,
line interruptions) are only transmitted to the I/O controller after release when
setting the module's parameters.
