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.
TwinCAT I/O provides configuration tools and drivers for different Windows versions for programs in any desired high level language (DLLs) and for Visual Basic applications (ActiveX). Applications with OPC interfaces can access the cards via an OPC server.
