Beckhoff FC7502 | Sercos II master card, 2 channels, PCI™



FC7502 | Sercos II master card, 2 channels, PCI™

The Sercos II PCI™ Fieldbus Cards from Beckhoff allow direct access to the SERCON816-ASIC.

The driver for these passive cards is incorporated into the TwinCAT software and allows optimum access to the Sercos interface.

There are no artificial limitations with regard to the number of bus devices and I/O data per device. The power of TwinCAT comes into its own with this interface generation:

up to 254 devices (axes, I/O modules, e.g. Bus Terminals with Bus Coupler BK7500)

any assignment and length of the I/O data

exact synchronization between TwinCAT and Sercos

cycle times from 62.5 µs are possible

synchronous communication of process data

Master mode can be parameterized by software.

It is possible to select two parallel fieldbus channels on one card (2 x SERCON816).

Synchronization of both channels and other cards along with PC is possible.

Upload of network configuration is supported.
