Embodiment Construction

[0041] The present invention will be further described in detail below in conjunction with specific embodiments.

[0042] It should be noted that these embodiments are only used to illustrate the present invention, rather than to limit the present invention, and the simple improvement of the method under the premise of the concept of the present invention belongs to the protection scope of the present invention.

[0043] see figure 1 , 2 , which is a serial port-based IO communication method for an industrial robot controller, comprising: an industrial robot controller, an IO board and a plurality of motion modules, and the industrial robot controller is respectively connected with the IO board and the plurality of motion modules ;

[0044] The industrial robot controller is powered on and initialized, enters the state of "in the stage of preparing for configuration, no data interaction is performed", and waits for a configuration request, and the IO board with the serial po...

Abstract

The invention relates to the technical field of IO communication, in particular to an IO communication method and system of an industrial robot controller based on a serial port. Before communication, an IO board periodically sends a configuration request to a serial port through a serial port, after an industrial robot controller receives default IO configuration, DI, DO, AI and AO to be interacted and a communication period are negotiated and configured, a configuration response is sent, after negotiation is passed, the two parties enter periodic IO data interaction, and each path of DI/DO/AI/AO in the IO board has a unique description SDO; the serial port chip is used for replacing an EtherCAT slave station chip, the purposes of low cost and sufficient goods sources are achieved, and one-to-one reliable communication is achieved under the Baud rate agreed by the two parties and the full duplex serial port environment; and the communication method can be automatically recovered after communication interruption, so that the use is convenient.

Description

technical field [0001] The invention relates to the technical field of IO communication, in particular to a serial port-based IO communication method and system for an industrial robot controller. Background technique [0002] Industrial robots are multi-joint manipulators or multi-degree-of-freedom mechanical devices widely used in the industrial field. They have certain automation and can realize various industrial processing and manufacturing functions by relying on their own power energy and control capabilities. Industrial robots are widely used in various industrial fields such as electronics, logistics, and chemicals; [0003] The industrial robot controller (hereinafter referred to as the controller) needs to communicate with the IO board (input and output board: DI is digital input, DO is digital output, AI is analog input, AO is analog output), generally using EtherCAT (industrial Real-time Ethernet) protocol to communicate with the IO board, the IO board must use...
