The CP 243-1 communications processor is used to connect S7-200 to Industrial Ethernet.
Distributed plants can be reached over telephone lines or the Internet by using a router and simple diagnostics, signal or user functions can be performed with the help of a web browser. The CP 243-1 is especially suited for plant sections where using PCs for permanent monitoring functions would not be cost-effective.
PC applications can access the data of an S7-200 via an S7 OPC server. In this way, process data can be easily archived or further processed.
SIMATIC S7-300 and S7-400 programmable controllers can communicate with a SIMATIC S7-200 with CP 243-1 over Industrial Ethernet which means that the S7-200 can also be used for more complex applications.
