CI801 Configuration Rules

The maximum number of S800 I/O stations per bus is: 99 stations
Supported communication speeds: 9.6 kbit/s to 12 Mbit/s
The maximum number of S800 I/O stations per bus segment is: 32 stations
The maximum number of I/O modules in a station is: 24 modules
The maximum number of I/O modules per cluster is: 12 modules
It is not allowed to physically install more than 12 MTUs and/or S800L modules in
a cluster.
Due to the PROFIBUS-DPV1 specification, it is not possible to always connect 24
I/O modules to one FCI. The reason is that the S800 I/O system includes more data
and user parameters than PROFIBUS-DPV1 can handle.
