Problems solved by technology

[0006] The main purpose of this application is to provide a distribution-based scanning method to solve the problem that most of the devices on the market are communicating based on IP addresses. Before communication, you must first specify the IP address of the device. If you do not know the IP address, you must pass It is a troublesome problem to view the communication of devices such as serial ports

Abstract

The invention discloses a scanning method based on distribution. The scanning method comprises the steps that 1, programming software sends a search frame of a specific command to all equipment in a local area network in a UDP broadcasting mode; 2, after receiving the broadcast frame, a motion controller returns equipment unique information and communication information of the controller; 3, the programming software reads the broadcast reply frame in an asynchronous communication mode, and records the information of the equipment; and 4, the programming software displays all the found devicesin a list form, and the user clicks the devices to establish connection for communication. According to the method, the technical problems that most of equipment on the market communicates based on IPaddresses, the IP addresses of the equipment are specified before communication, and if the IP addresses are not known, communication checking needs to be carried out through equipment such as a serial port and the like, so that the operation is troublesome are solved.

Description

technical field [0001] The invention relates to the technical field of the Internet of Things, in particular to a distributed scanning method. Background technique [0002] With the development of Industry 4.0, customers have more and more demands on devices connected to the network, and the same customer often needs to operate more than one device. At this time, a quick connection device solution is needed, which can be convenient and fast Connect to the device for programming and maintenance of the device. [0003] During the development process of programmable controller, it gradually develops from simplification to modularization and informationization. There are more and more demands for networking. It is a good solution based on the mature TCP / IP protocol. This technology provides a convenient and fast communication method on the basis of the TCP / IP protocol, so that customers can quickly Locate, connect to, program and maintain equipment. [0004] However, most o...
