CN 4100 single without CMs
The innovative communications node SIMATIC CN 4100 is a flexible and powerful platform for all communication tasks. Thanks to its scalable, modular design and the option of connecting third-party systems, SIMATIC CN 4100 can be used to implement efficient system concepts for process control technology.

Powerful data communication via Ethernet:
SIMATIC CN 4100 can be connected to the Industrial Ethernet bus system via the integrated Ethernet interfaces.
Connectivity to a SIMATIC PCS neo AS-410 is established via the plant bus over interfaces X1 and X2 of the CN 4100. The data exchange between CN 4100 and S7-410 takes place via TCP communication based on the relevant libraries. The two other interfaces are used to connect OPC UA servers and/or MODBUS/TCP devices.
The assignment of the interfaces is as follows:
G_PCS7_XX_01095
A singular SIMATIC CN 4100 station uses the X1.x interfaces. In the redundant configuration, the X2.x interfaces are also used for the second CPU module (only single operation is permitted for PCS neo 4.0).
Design
ENG_866792.XML
SIMATIC CN 4100 consists of the following components:
CPU module
P_PCS7_XX_00841
CN 4100 CPU
The CPU module is the central module of the SIMATIC CN 4100. All operations and communication tasks are carried out by the CPU. For each CPU, there is one interface for the connection to the plant bus and two separate interfaces for the connection to the end devices (e.g. OPC UA server or MODBUS/TCP device)
The following protocols are currently supported:
Singular configuration (1x CPU):
- OPC UA DA client
- MODBUS/TCP
- TCP communication (TCPCon library)
Rack
The SIMATIC CN 4100 rack offers connection options for 2x CPU modules and 2x communications modules (in PCS neo 4.0, only single operation and no expansion modules are permitted). The integrated Ethernet interfaces provide the connectivity. The rack is installed by screwing it onto a mounting plate in the control cabinet.
X1.x interfaces are assigned to CPU1, X2.x interfaces are assigned to CPU2.

SIMATIC PCS neo system connection
- User-friendly commissioning thanks to full system integration
- Integration in SIMATIC PCS neo with CN 4100 block library
Security
Due to an integrated firewall, there is no connection between the plant bus interfaces X1 and X2 and the lower-level networks that are connected via the other interfaces (e.g. OPC UA server, MODBUS/TCP devices).
There is no routing between the networks.
