Delivery release Profibus modules S7-1200

  • Entry
  • Associated product(s)

The Profibus modules for S7-1200 are available for immediate delivery.

 

The communication options of the SIMATIC S7-1200 automation system are expanded by the Profibus DP fieldbus standard. The connection of a S7-1200 to Profibus takes place with the new communication modules CM 1242-5 and CM 1243-5.

 

By connecting the new modules to the communication bus of the S7-1200, the controller can exchange I/O data as Profibus master and/or Profibus slave with other Profibus nodes. The modules meet Profibus standard DPV1 and satisfy the high requirements regarding robustness and safety of the fieldbus system used most widely around the world.

 

The CM 1243-5 also supports the connection of programming devices and panels as well as an acyclical data exchange.
