PROFIBUS data transfer). The backplane input block reserves 8 words for general purposes and

the backplane output block reserves 5 words. You must subtract these reserved words from the

total I/O block size to calculate the actual number of PROFIBUS I/O data per backplane I/O block

and where the break points between data blocks will be in the PROFIBUS data arrays.
