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

The efficient, reliable and rugged communication processor that links the S7-300 via Industrial Ethernet, also as a PN IO controller for the connection of PROFINET.

In addition to the functionality of the CP 343-1, the CP 343-1 Advanced offers e-mail functions and user-created web pages and thus optimally supports maintenance and quality assurance. The Internet functions such as FTP even allow connection to the most diverse PC-based systems. Therefore, for the S7-300, this CP is the bridge between the field level and the MES level.

In combination with a loadable firmware expansion, this communication processor offers efficient access via Industrial Ethernet to databases across all corporate levels without laborious programming of the controller.
