GENERAL DESCRIPTION
The SERCOS interface controller SERCON410B is anintegrated 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 (65 µs to 65 ms). It is appropriate for the synchronous operation of distributed control or test equipment (e.g. connection between drives and numeric control).

■ Single-chip controller for SERCOS interface
■ Real time communication for industrial control systems
■ 8/16-bit bus interface, Intel and Motorola control signals
■ Dual port RAM with 1024 words * 16-bit
■ Data communications via optical fiber rings, RS 485 rings and RS 485 busses
■ Maximum transmission rate of 4 Mbaud with internal clock recovery
■ Maximum transmission rate of 10 Mbaud with external clock recovery
■ Internal repeater for ring connections
■ Full duplex operation
■ Modulation of power of optical transmitter diode
■ Automatic transmission of synchronous and data telegrams in the communication cycle
■ Flexible RAM configuration, communication data stored in RAM (single or double buffer) or transfer via DMA
■ Synchronization by external signal
■ Timing control signals
■ Automatic service channel transmission
■ 100-pin plastic flat-pack casing
