The right CP for any requirement


Within the controller family, the SIMATIC S7-400 is designed for system solutions in manufacturing and process automation in the medium to upper performance range. The connection of SIMATIC S7-400 via communications processors permits direct integration of the controllers into Industrial Ethernet networks. The communication processors have multi-protocol capability and support the following protocols:

  • PG/OP communication

  • S7 communication

  • open communication (SEND/RECEIVE)


  • IT communication

CP 443-1: Convincing performance capability

CP 443-1

The low-cost connection for programming devices and HMI devices, as well as for communication between S7 programmable controllers.

CP 443-1 Advanced: The high-power version with Gigabit uplink and 4-port switch on board

CP 443-1 Advanced

In addition to the proven industrial features of the CP 443-1, the CP 443-1 Advanced, with IT functionalities such as e-mail, http-based diagnostics and user-created web pages, offers the ideal support for maintenance and quality assurance. The Internet functions such as FTP communication even allow direct connection to the ERP level without additional gateways. Thanks to two separate interfaces, the CP is suitable for network separation between control and field level, e.g. for load coupling. The integrated 4-port switch on the second interface is particularly suitable for setting up small networks, e.g. for the connection of PROFINET I/O devices. That's why this CP represents the the bridge between the field level over PROFINET and the MES level for the S7-400.
