Communication Processor securely connects PLC to Ethernet.
December 27, 2012 -
By combining security features such as SPI firewall, password requests, and data encryption protocols such as FTPS and SNMPv3, Simatic CP 1543-1 communication module protects individual Simatic S7-1500 stations or entire automation cells against unauthorized access on Ethernet networks. Administrator can regulate access to Simatic S7-1500 via detailed firewall rules in CP 1543-1, and processor also supports IPv6 protocol, open communication via TCP and UDP, as well as S7 communication.

Press release date: December 27, 2012
The Simatic CP 1543-1 communication processor from the Siemens Industry Automation Division securely connects the Simatic S7-1500 controller to Ethernet networks. By combining a variety of security features such as an SPI (Stateful Packet Inspection) firewall, password requests and data encryption protocols such as FTPS and SNMPv3, the new communication module protects individual S7-1500 stations or even entire automation cells against unauthorized access. This allows the PLC to communicate with higher-level control systems or industrial IT applications via a secure Ethernet connection. The administrator can regulate access to the Simatic S7-1500 by means of detailed firewall rules in CP 1543-1. The new communication processor also enables data transmission using the FTP/FTPS protocol. Furthermore, the module supports the IPv6 protocol, open communication via TCP and UDP as well as S7 communication. TIA Portal Version 12 is used for configuring all functions. The communication processor makes its diagnostic information available to the S7-1500 controller; the user can then view and analyze this information via the front display by means of the TIA Portal or the S7-1500 web server.
The Simatic CP 1543-1 has an RJ45 connector for establishing connections to Industrial Ethernet networks. Data can be transmitted using the full or half duplex process in bandwidths of 10, 100 and 1000 Mbit/s. The communication processor also ensures consistent time synchronization in the NTP (Network Time Protocol) process within the connected S7 station. Among other things, this can help identify protocols, error messages or synchronization problems within the network.
