The Siemens Industry Automation Division has developed two new 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 12 Megabit/second, for example 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 cannot supply sufficient power.
The Profibus and USB connectors can be locked mechanically …
