Beckhoff Automation (Verl, Germany) has released Mini PCI fieldbus cards for PROFIBUS, CANopen, DeviceNet and Ethernet networks. With the Mini PC cards, the newest Beckhoff Industrial PCs, including the C69xx cabinet PCs and the CP62xx or CP72xx Control Panel PCs, are equipped to integrate additional fieldbus technologies.

The Ethernet Mini PCI cards give Industrial PCs a third available Ethernet port with 10 Mbit/s, 100 Mbit/s, or 1000 Mbit/s communication. The fieldbus cards are most powerful when using Beckhoff TwinCAT PLC and NC software, but benefit other applications as well. The bus interface is not implemented on the fieldbus card, but separately in the PC housing (devicespecific). The cards are available with optional NOVRAM.
