Profibus via USB

Siemens has introduced two communications processors for connecting PCs and S7-300 controllers to Profibus and industrial Ethernet, respectively. Simatic Net CP 5711 is an external adapter that links commercially available PCs to Profibus via their on-board USB 2.0 port. The Simatic Net CP 343-1 ERPC expansion module connects Simatic-S7-300 controllers with databases via industrial Ethernet.

The Simatic Net CP 5711 communications processor supports all MPI and Profibus communications services up to a rate of 12Mbit/s; for example, DP Master/DP Slave, S7/S5 and PG/OP. The Profibus and USB connectors can be locked mechanically so that cables are securely connected in a typical commissioning and servicing environment.

Simatic Net CP 343-1 ERPC is used for directly connecting Simatic-S7-300 controllers to database systems via industrial Ethernet. This enables controllers to be supplied with data or jobs directly from databases on a manufacturing execution systems or enterprise resource planning management level.
