Application and functions

1.4 Configuration limits and performance data

Another option is for this station to be synchronized via a different LAN. The synchronization
frame can be forwarded from the CP to the PROFIBUS network for the synchronization of
further stations.
The CP supports time stamping of distributed process signals in conjunction with the IM 153.
Time-of-day status value (standard/daylight saving time switchover, synchronization status)
Note
Time master is the CPU
Note the following fundamental behavior of the SIMATIC S7-4100:
The CPU synchronizes all modules in the rack.
Module replacement
The configuration data of the CP is always stored on the CPU. This means that replacing
modules is possible without having to download the configuration data via the engineering
station.

Rack components

Use of multiple CPs
By operating several CPs, you can increase the configuration limits listed below for the station
as a whole.
The CPU does, however, have set limits for the entire configuration. Observe the information
in the documentation of the CPU, see /3/ (Page 41).
CP quantity
The following limits apply to the number of CPs in a station:
• Installation in the bus module
The number of CPs is dependent on the power supply:
– 1 power supply module plugged
– 2 power supply modules plugged (redundant power supply)
• Installation with U-connector
A maximum of five CPs can be plugged.
You can find more detailed information on the maximum number of modules and the
maximum configuration in the SIMATIC S7-4100 system manual; see /2/ (Page 41).
12
A maximum of five CPs can be plugged.
A maximum of four CPs can be plugged.
