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.
