The innovative communication node SIMATIC CN 4100 is a flexible and powerful platform for all communication tasks. Thanks to its scalable, modular structure and the option of connecting third-party systems, the SIMATIC CN 4100 can be used to implement efficient system concepts for process control technology.

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 SIMATIC CN 4100 can be operated singularly as well as redundantly.

The redundant configuration of the SIMATIC CN 4100 offers significantly higher availability. It works according to the 1-of-2 principle, whereby in the event of an error the active CPU is switched to the backup CPU. You can also set up the power supply redundantly for each subsystem.

 

The following protocols are currently supported singularly/redundantly:

Singular configuration (1xCPU):

  • OPC UA DA client
  • MODBUS/TCP
  • S7 communication (PUT/GET)

 

Redundant configuration (2xCPUs)

  • MODBUS/TCP
  • S7 communication (PUT/GET)
