Siemens  have developed two new communications processors for connecting PCs and S7-300 controllers to Profibus and Industrial Ethernet. Simatic Net CP 5711 is an external adapter that links commercially available PCs to Profibus through its on-board USB 2.0 port. The Simatic Net CP 343-1 ERPC expansion module connects Simatic-S7-300 controllers with databases through Industrial-Ethernet.

The Simatic Net CP 5711 communications processor supports MPI and Profibus communications services up to a rate of 12 Megabit/second, such as DP Master/DP Slave, S7/S5 and PG/OP. The module has a 24 volt power supply connection in case the USB interface of the PC is unable to supply sufficient power. The Profibus and USB connectors can be locked mechanically, so that cables are connected in a typical commissioning and servicing environment. The new communications processor can also optionally be mounted on a DIN rail.

The Simatic Net CP 343-1 ERPC expansion module is used for directly connecting Simatic-S7-300 controllers to database systems through Industrial Ethernet. This enables controllers to be supplied with data or jobs directly from databases on the Manufacturing Execution Systems (MES) or Enterprise Resource Planning (ERP) management level. In addition to the connection with other automation systems such as Simatic controllers, PCs or control systems, the Simatic Net CP 343-1 ERPC expansion module allows for direct linking of databases such as Oracle, MySQL, MS-SQL and DB2 using optional software packages.
