Scenario 4: The PROFIBUS data fits into ten backplane blocks (same PROFIBUS data count
per block)
For this scenario, each backplane block reserves 10 words for PROFIBUS I/O
data. The configured PROFIBUS I/O size (100 words) will not fit into one block,
so ten backplane input blocks and ten backplane output blocks will be required.
