Simple Industrial Ethernet connection for the Simatic S7-300 controller

The Simatic NET CP 343-1 Ethernet communications processor is particularly easy to connect using RJ45 technology, and it has been designed especially for TCP/IP communication. The product brings Industrial Ethernet connectivity to the Simatic S7-300 range, and is equipped with its own processor to offload the controller CPU of communication tasks.

Arranging the RJ45 socket at an angle facilitates the use of the new RJ45 FastConnect plugs. The connections for the power supply are run through a plug-in contact, making it easier for service personnel to replace modules.

New process technology makes the CP343-1 faster than its predecessor in addition to offering higher data throughput. It is now also possible to connect up to 16 HMIs to one S7-300 controller via Ethernet TCP/IP.

The new CP is configured using Step7 software, and the configured data can also be saved on the CPU of the S7 controller, so a programming device is no longer required when replacing the card. The communications processor has its own unique MAC address, so it can be initialised directly over Industrial Ethernet.
