Communications processors for Advanced Controller S7-1500/300/400

More dynamic, faster, more cost-effective

To continue to be one decisive step ahead of the competition, you must solve your PLC tasks dynamically, fast, and cost-effectively.

Our communications processors relieve the controller’s CPU of communications tasks and facilitate additional connections. They permit suitable integration into Industrial Ethernet and implement connections both at the automation level and to the IT world and up into the cloud.

Communication processors for SIMATIC-S7 300

With our comprehensive portfolio, we offer the right CP for every requirement, as lean, standard or added value versions for SIMATIC S7-300, the modular controller for innovative system solutions in the manufacturing industry. Connecting controllers via these CPs permits direct integration 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)

  • PROFINET communication

  • IT communication

CP 343-1 Lean

CP 343-1 Lean: Connects even small applications to Industrial Ethernet

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

CP 343-1

CP 343-1: The tried and tested, rugged and secure standard versions

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.

CP 343-1 Advanced

CP 343-1 Advanced: From PROFINET to IT communication

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.

With its integrated security functions of firewall (Stateful Inspection), VPN protocol (IPSec) and protocols for data encryption such as FTPS and SNMPv3, the communications processor protects S7-300 stations and lower-level networks against unauthorized access, as well as protecting data transmission against manipulation and espionage by means of encryption. Therefore, for the S7-300, this CP is the bridge between the field level and the MES level.

CP 343-1 ERPC

CP 343-1 ERPC: Connects SIMATIC S7-300 controllers with ERP / MES systems

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.
