Extended controller communication
04/04/2013 Siemens Industry Automation & Drive Technologies
Nuremberg, Germany. The Siemens Industry Automation Division has developed a new Profibus module and extended the security functions in Simatic S7-1500 controller communication via Industrial Ethernet.The new CP 1542-5 communication processor provides a connection between smaller Profibus networks and Simatic-S7-1500 controllers, allowing, for instance, the creation of additional Profibus segments to relieve the S7- 1500 CPU from communication func- tions. CP 1542-5 supports Profibus-DP master and slave functions according to the international standard IEC 61158/61784 as well as S7 routing.
Security functions have been exten- ded in the CP 1543-1 communication processor used to connect Simatic S7-1500 controllers to Industrial Ethernet networks. One of these functions provides additional encryption of data communicated to the controller, thus protecting it more effectively against interception or manipulation. For this purpose, VPN(Virtual Private Network) connections are set up with the communication partner. Encryption is based on the standardized IP-Sec protocol. In addition to the access protection functions in the form of password protection which is already supported by Simatic S7-1500 CPU, CP 1543-1 offers a stateful inspection firewall for accessing the S7-1500.
