Configuration limits and performance data

1.4.1

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 49).
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 49).
1.4.2

PROFINET IO characteristic data

Configuration limits of the CP as IO controller
The CP supports the following maximum configuration as a PROFINET IO controller:
Characteristic
Number of operable PROFINET IO devices
Size of the input area over all PROFINET IO devices
Size of the output area over all PROFINET IO devices
Size of the IO data area per submodule of a module in an IO
device
Size of the consistency area for a submodule
Number of submodules to be supported as CP for PN IO
controller
SIMATIC CP 4163-1
Operating Instructions, 12/2022, C79000-G8976-C588-01
A maximum of five CPs can be plugged.
A maximum of four CPs can be plugged.
