Product Description:
The FC7501-0000 is a PCI fieldbus interface card produced by Beckhoff within the FC Lightbus Cards series. Fitted in an industrial PC, the board links the host controller to a fiber-optic Lightbus ring so real-time process data moves between drives, remote I/O, and motion axes with deterministic timing. By delegating cyclic telegram handling to on-board logic, the card frees the CPU for higher-level control tasks required in automated assembly cells and packaging lines. This arrangement suits control platforms that must coordinate distributed devices while maintaining predictable data exchange across an optical network.
Two optical ports of type 2 x FSMA (IEC 874-2) connect the board to the Lightbus fiber. Communication is executed by the SERCON816 ASIC, and the host gains direct DPRAM and SERCON816 register access through the PCI bus to minimize software overhead. Adjustable signaling speeds of 2/4/8/16 Mbaud let the system balance bandwidth against link distance. Although only one fieldbus channel is present, it supports the SERCOS II protocol so servo drives and sensors receive tightly scheduled data. In this mode, cyclic exchanges can be achieved with a minimum period of 62.5 µs, a rate compatible with coordinated multi-axis motion. Synchronization with other Beckhoff cards is possible through an external ribbon cable for aligned timing between boards.
Hardware status is provided by 1 LED/Channel, enabling visual verification of link integrity during operation. A single Lightbus loop can address up to 254/Channel remote devices, supporting complex machines without intermediate hubs. The PCI slot demands only 180 mA Typ. of supply current, limiting heat generation inside compact control cabinets. That modest current draw helps preserve thermal headroom when multiple expansion cards share the same enclosure. Data moves across a 32 bit host interface, allowing memory-mapped transfers that keep CPU usage low during high-frequency acquisitions.
