MOTION CONTROLLER DEVICE AND COMMUNICATION METHOD THEREIN

摘要

A motion controller device and a communication method for the motion controller device are provided to reduce the large number of man-hours that are required for making communication settings and wiring design in large-scale systems. The motion controller device and communication method improve the degree of freedom for communication line connections by switching the two transmission paths on the transmitting and receiving sides of the communication ports contained within a central communication device and a terminal communication devices for full duplex communications. The motion controller device and communication also ensure the response performance required in the devices being controlled by way of the terminal communication device that autonomously and dynamically switches the communication paths according to the volume of communication data on the communication line along this type of network.

主权项

1. A motion controller device comprising one or more terminal communication devices that execute input and output operation or control processing of the devices for control, and a central communication device coupled to the terminal communication device by way of a network;
wherein the motion controller device further includes a communication path between at least one communication port of the central communication device and any one of the communication ports of the terminal communication device; the motion controller device further includes a communication path between at least one communication port of the terminal communication device and any one of the communication ports of the central communication devices, or any one communication ports of the other terminal communication device; a network is configured in this way, and the terminal communication device is therefore capable of coupling to a plurality of transmission paths, and the transmit and receive units of the communication port contained in the terminal communication device include a transmit and receive switching unit.
