SERC816

SERC816 is a SERCOS interface controller. It is an integrated circuit for SERCOS interface communication systems. The SERCOS interface is a digital interface for communication between systems that have to exchange information cyclically at short, fixed intervals (62.5s to 65ms). It is appropriate for the synchronous operation of distributed control or test equipment (e.g. connection between drives and numeric control). A SERCOS interface communication system consists of one host and several servers. It is connected by a fibre optical ring. This ring starts and ends at the host. The server regenerate and repeat their received data or send their own telegrams. The optical fibre assures a reliable high-speed data transmission with excellent noise immunity. The SERCOS interface controller contains all the hardware-related functions of the SERCOS interface and considerably reduces the hardware costs and the computing time requirements of the microprocessor.
