Abstract

A single line bidirectional communication method of a reconfigurable controller belonging to the technology field of communication engineering is provided. Through upper computer interface conversion module, the invention transforms positive and negative logical signals of serial communication into difference voltage signal and sends to a signal processing module, wherein, a microprocessor is for processing and responding to delivered message protocol, conversely, the information can also be sent from reconfigurable controller to the upper computer, and the delivered message protocol can be responded by the upper computer, during responsion, corresponding operations are executed according to different operating commands, the commands comprise starting parameterization, reading erasable memorizer operation, writing erasable memorizer operation, whole piece erasure operation of the erasable memorizer, stopping parameterization; during the operation execution, the communication state is displayed in real-time according to real-time communication state. By utilizing the characteristic of single line communication in the invention, wire harnesses are reduced for more than a half than universal serial or other wired communication, thereby realizing the stability of information interaction and data transferring of each numerical module.

Description

technical field [0001] The invention relates to a method in the technical field of communication engineering, in particular to a single-wire bidirectional communication method for a reconfigurable controller. Background technique [0002] Reconfigurable controllers have become an inevitable trend in the development direction of controllers because of their good characteristics such as modularization, openness and portability. As the link between the reconfigurable controller and the NC module, information communication is used to send the instructions or data of the reconfigurable controller to the corresponding NC module to adjust the processing sequence of the NC module or realize other functions. Feedback the adjusted information state of the numerical control module to the controller. Compared with the communication mode of the traditional controller, the communication mode of the reconfigurable controller is more flexible and open, which solves the shortcoming of the c...
