New PC Fieldbus cards for SERCOS interface
Keywords: Fieldbus, Drives
Hayes Control Systems has launched two new PC Fieldbus cards specifically for SERCOS applications, the FC7501 and FC7502. The new cards extend the diverse range of PCl-based Beckhoff products, offering solutions for fast bus drives to all users of complex access controls (Plate 5).

New PC Fieldbus cards for SERCOS interface
Allowing optimum access to the SERCOS interface, the driver for the passive FC7501 (one channel) and FC7502 (two channel) cards is incorperated into TwinCAT, the powerful PC-based automation control software solution from Hayes.
By using the new Fieldbus cards together with bus terminals as I/O systems, digital servo drives and TwinCAT as PLC/NC software, it is possible to achieve a complete PC-based control system for the SERCOS interface.
With the new cards users expenence no limitations with regards to the number of bus devices and I/O data per unit, making large SERCOS projects of more than 50 axes possible. To do so, several PCs need to be synchronised via SERCOS, with one PC acting as master and other PCs as "slaves". In such situations the FC7502 twin-channel card can generate one master nng and one slave nng, with the parameterisation of the master/slave mode carried out simply and efficiently through the software.
To complete its SERCOS offering Hayes has also introduced the Beckhoff SERCOS BK7500 Bus Coupler, enabling SERCOS' high deterministic function to be used for classic I/O technology. This additional feature allows users in the machine construction industry, with high-drive and low I/O consumption, to dispense with the installation of an additional bus.
With up to 254 devices (axes or I/O modules via Bus Coupler) a fast data exchange via cycle times of up to 62.5 usec, and a transmission rate of 2 and 4 Mbaud, the FC7501 and FC7502 are a valuable addition to the Hayes Control Systems range.
