Siemens' Ethernet module links micro PLC to automation system


Alpharetta, GA- Siemens Energy & Automation Inc . introduced on Sept. 30 a new communications processor, CP 243-1, for its Simatic S7-200 micro PLC that eases connections to Ethernet networks.

CP 243-1 communications processor is linked to 10/100 Mbit/s Ethernet with RJ45 connectors and to a 24-V power supply by a terminal strip. The module can be installed on a DIN rail or surface mounted for integration of S7-200 into existing Ethernet networks.

Likewise, the Simatic CP 243-1 extension module for the S7-200 provides seamless, high-speed data exchange between S7-200 CPUs or to higher-level automation systems, such as Simatic PLCs or HMI products, as well as to PC-based systems via an OPC interface. Combined with other S7-200 expansion modules, CP 243-1 can also serve as an intelligent gateway between Ethernet and a field-level Profibus network or AS-interface device network.
