Description of Diagnostic Information for WAGO I/O Modules

The WAGO I/O module diagnostic information is stored beginning with array
element EXTENDEDINFO[23]. Decoding of the diagnostic information is shown
here using the dual channel, 750-466 input module as an example.

10000100 Slot for input module; in this case the third (slot 4).
Note:
The first slot is reserved for the fieldbus coupler and
controller including the supply module. Therefore,
the first I/O module is inserted in the second slot.
