Difference between Real and Expected Configuration

The fieldbus coupler provides diagnostic information in the event of module
differences in the form of a "ModuleDiffBlock" when there are deviations
between the module/submodule configuration of the IO controller and the IO
modules actually connected.
The "BlockType" in the head structure of the data set corresponds to the value for
module differences (0x8104). The length gives information on the differences
between the configured and connected modules/submodules.
The "ModuleDiffBlock" is initiated with the following head structure.

The entries for the incorrectly configured modules/submodules then follow. The
number of existing entries is stored in the preliminary structure of the
"ModuleDiffBlock".
