Scenario 1: The PROFIBUS data fits into one backplane block
This example uses the following backplane configuration:
For this scenario, each backplane block reserves 100 words for PROFIBUS data,
so the data fits into one backplane I/O block. The module will generate two block
IDs, blocks 0 and 1, in order to force a Block ID switch, as required for the ladder
logic to function correctly, but both blocks will contain the same data.
