Calculation of Number of S800 I/O Modules per Station
Due to the PROFIBUS-DP specification it is not possible to always connect 24
I/O modules to one FCI. This is because the S800 I/O system includes more data
and user parameters than PROFIBUS-DP can handle.
number of modules that can be connected to one CI801.
