siemens-157-03-2014Siemens has introduced three new communication modules for Simatic S7-1200 and two matching industrial routers with which remote terminal units (RTUs) can be implemented economically. The communication modules CP 1243-1, CP 1243-1 DNP3, and CP 1243-1 IEC connect the Siemens control via the telecontrol basic and telecontrol professional systems to higher-level systems or to a control center. The company is also expanding its industrial communication portfolio for telecontrol and teleservice applications with two mobile wireless routers, Scalance M874-2 and Scalance M874-3. The CP 1243-1 module is based on the basic telecontrol system, which is designed for simple applications and small data volumes. The CP 1243-1 DNP3 and CP 1243-1 IEC modules can establish the connections according to the DNP3 and IEC 60870-5-104 telecontrol protocols. They use the professional telecontrol system for demanding monitoring and control tasks. The communication modules can be installed seamlessly alongside the Simatic S7-1200 controller.
