Hi,

A maximum of 124 slaves (CI840) can be connected to a CI854 since the node addresses 0 and 1 are reserved for CI854

Number of S800 I/O Stations

Maximum number of S800 I/O stations per bus:


Redundant CI840: 62 stations.


Single CI840: 99 stations

 Supported communication speeds: 93.75 kbit/s to 12 Mbit/s



Maximum number of S800 I/O stations per PROFIBUS segment:


Communication speed 12 Mbit: 20 stations.

Communication speed 1,5 Mbit: 32 stations.


Maximum number of S800 I/O modules in a station: 24 modules

Maximum number of S800 I/O modules per cluster: 12 modules

Switch over time at failure in a redundant CI840 configuration is typical <100 ms and maximum 150 ms.

The 12 modules per cluster can either be 12 single I/O modules or 6 pairs of redundant I/O modules. Redundant I/O modules can only be mounted on the base cluster. It is not allowed to mix single and redundant I/O modules within a cluster. It is not allowed to physically install more than 12 single MTUs and/or S800L modules in a single cluster. It is also not allowed to physically install more than 6 redundant MTUs in a redundant cluster.
