CP 1243-1

The CP 1243-1 communication processor securely connects the SIMATIC S7-1200 controller to Ethernet networks. With its integrated security functions of firewall (Stateful Inspection) and VPN protocol (IPSec), the communications processor protects S7-1200 stations and lower-level networks against unauthorized access, and protects the data transmission against manipulation and espionage by means of encryption. Furthermore, the CP can also be used for integrating the S7-1200 station into the TeleControl Server Basic control center software via IP-based remote networks.

CP 1543-1

The SIMATIC CP 1543-1 communications processor securely connects the new SIMATIC S7-1500 controller to Industrial Ethernet networks. 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 S7-1500 stations and lower-level networks against unauthorized access, as well as protecting data transmission against manipulation and espionage by means of encryption.

Note:

Further information on CP 1243-1 and CP 1543-1 can be found Chapter 2, PROFINET/Industrial Ethernet, under "System connection for SIMATIC S7/communication for SIMATIC S7-1200 and SIMATIC S7-1500".

CP 1543SP-1

The CP 1543SP-1 communications processor connects the ET 200SP Distributed Controller with Industrial Ethernet networks. By combining a variety of security features such as an SPI (Stateful Packet Inspection) firewall, VPN and data encryption protocols (e.g. SNMPv3), the communications processor protects individual ET 200SP Distributed Controllers or even entire automation cells against unauthorized access.
