PROFIBUS CI840
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.
