S7-1200 Communication Modules

Siemens S7-1200 Communication Modules are used for quick, high-performance serial data exchange via point-to-point connection. Point-to-point connection is possible to, e.g.: SIMATIC S7 automation systems and the systems of many other manufacturers, Printers, Robot controls, Modems, Scanners, Bar code readers, etc.  CM 1241 is available with either a RS485 (6ES7241-1CH30-0XB0) connection or a RS232 (6ES7241-1AH30-0XB0) connection.

The CSM 1277 (6GK7277-1AA00-0AA0) is an Industrial Ethernet Switch of compact and modular design for use in the SIMATIC S7-1200. The CSM 1277 can be used to multiply the Ethernet interface of the SIMATIC S7-1200 in order to allow simultaneous communication with operator panels, programming devices, other controllers, or the office world. The CSM 1277 and the SIMATIC S7-1200 controller can be used to implement simple automation networks at low cost.

There is also a comprehensive range of accessories for the communication modules from IE FC TP Standard Cable (6XV1840-2AH10), IE FC RJ45 Plug 180 (6GK1901-1BB10-2AA0) and also the relevant IE FC Stripping Tools (6GK1901-1GA00).
