Product Summary
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).
Parametrics
SERCON816 absolute maximum ratings: (1)Supply voltage: -0.5 to 6.5 V; (2)Input voltage: -0.5 to VDD + 0.5 V; (3)Output voltage: -0.5 to VDD + 0.5 V; (4)Storage temperature: -55 to +150 ℃.
Features
SERCON816 features: (1)Single-chip controller for SERCOS interface; (2)Real time communication for industrial control systems; (3)8/16-bit bus interface, Intel and Motorola control signals; (4)Dual port RAM with 2048 word 16-bit; (5)Data communications via optical fiber rings, RS 485 rings and RS 485 busses; (6)Maximum transmission rate of 16 Mbaud with internal clock recovery; (7)Internal repeater for ring connections; (8)Full duplex operation; (9)Modulation of power of optical transmitter diode; (10)Automatic transmission of synchronous and data telegrams in the communication cycle; (11)Flexible RAM configuration, communication data stored in RAM (single or double buffer) or transfer via DMA; (12)Synchronization by external signal.
