Description

technical field [0001] The invention relates to a communication system in the technical field of wired transmission, in particular to an IEEE 1394 communication interface system for a motion controller. Background technique [0002] Most of the modern motion control systems use motion controllers based on computer standard bus, and realize communication by connecting the bus between the host computer and the motion controller. The bus forms used in the motion control system are various, including ISA interface, PCI interface, VME interface, RS232 interface, USB interface, and field network communication interfaces such as Ethernet, RS485, SERCOS, and Profibus. At present, the emerging IEEE 1394 standard has gradually become one of the popular interface standards on computers. Compared with other bus forms, the main advantage of IEEE 1394 for motion control is that on the one hand, it supports peer-to-peer communication, and each IEEE1394 node can execute things independentl...
