Abstract: This paper introduces an application of IEEE 1394 bus in servo control system. It designs a 1394 front-end communication module to transform the data. The front-end module, in which a DSP processor is used to control the corresponding IEEE 1394 chip, realizes the high speed IEEE 1394 bus interface between CNC and servo units. Both the hardware and software design of 1394 front-end communication module are described. Communication experiments, between 1394 front-end communication module, host computer and motion controller, validate the feasibility of the application of IEEE 1394 bus in servo control system.

Key words: IEEE 1394 bus, Digital Signal Processor(DSP), servo control system
