Description
General part information
SERC816 Series
The SERCOS interface controller SERCON816 is an integrated circuit for SERCOS interface communication systems. The SERCOS interface is a digital interface for communication between systems which have to exchange information cyclically at short, fixed intervals (62,5 s to 65 ms). 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 master and several slaves. These units are connected by a fiber optical ring. This ring starts and ends at the master. The slaves regenerate and repeat their received data or send their own telegrams. By this method the telegrams sent by the master are received by all slaves while the master receives data telegrams from the slaves. The optical fiber 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. It is the direct link between the electro-optical receiver and transmitter and the microprocessor that executes the control algorithms. The SERCON816 can be used both for SERCOS interface masters and slaves.
