SIEMENS CSM 1277 - S7-1200, unmanaged switch

The CSM 1277 is an industrial Ethernet switch in a compact, modular design for the SIMATIC S7-1200. With the CS1277, the Ethernet interface of the S7-1200 can be multiplied in order to allow simultaneous communication with operating and programming devices, other controllers or the office world. The compact switch module CSM 1277 extends the SIMATIC NET product family with an unmanaged switch in S7-1200 component format. The module is used to connect a SIMATIC S7-1200 and up to 3 other participants to an industrial Ethernet network with 10/100 Mbit/s in electrical line, tree or star structure. Essential characteristics of the CSM 1277 are: • 4-port unmanaged switch • Industrial design of the new SIMATIC generation • Space-saving, optimised for connection to SIMATIC S7-1200 • Easy connection through RJ45 standard connectors • Cost-effective solution for small, local Ethernet networks With the CSM1277 and the S7-1200 control, simple automation networks can be realised at a low cost. Performance: • Up to 3 additional participants • Ethernet 10/100 MBit/s unmanaged switch • 4x RJ45 ports • External 24-V power supply • LED diagnostics • Including device manual on CD
