Problems solved by technology

[0002] At present, there are many products and production lines in many factories, and most of them use Mitsubishi FX2N series PLC. Sometimes some problems will occur on site after debugging, and some very simple program adjustments are required. If there is no remote debugging function, it is necessary to send people to the site to solve the problem. A great waste of manpower and material resources of the enterprise, and a waste of the energy of the technicians

Embodiment Construction

[0010] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0011] refer to figure 1 , the present embodiment adopts the following technical solutions: the method for remotely debugging the programmable controller by the telephone line in different places, and its steps are: 1, first carry out initialization programming to the V9.2 industrial MODEM of the programmable controller end, and write instructions to allow it With automatic answering function, to realize that when the computer end connects to the PLC end MODEM through MODEM dial-up, the PLC end MODEM can automatically answer, so as to realize the remote sending and receiving of program data between the computer and the PLC;

[0012] 2. Make the connecting cable between MODEM, programmable controller and computer; figure 1 As shown, the computer a...

Abstract

The invention discloses a method for remotely debugging a programmable controller in different places through a telephone line, and relates to a speed-regulation programmable control technology. Implementation steps of the method are as follows: (1) initial programming is firstly performed on V9.2 industrial MODEMs of a programmable controller end, and an instruction is written into the MODEMs so that the MODEMs have an auto-answer function, (2) fabrication are performed on connecting cables between the MODEMs, the number programmable controller and a computer, and (3) after the connecting cables between the equipment at two ends and the MODEMs find appropriate line sequences, two ends of the computer and the PLC are respectively connected with the telephone line, the MODEMs are electrified, a GX-DEVELOPER software is opened on the computer, a dialing function in the software is selected, and a telephone number connected with the MODEMs at one end of the PLC is dialed through as like making a call. The method provides convenience for remote debugging, has the advantage of time-saving and labor-saving performance, and greatly reduces technical personnel's work intensity.

Description

technical field [0001] The invention relates to a speed-regulating programmable control technology, in particular to a method for remotely debugging a programmable controller through a telephone line. Background technique [0002] At present, there are many products and production lines in many factories, and most of them use Mitsubishi FX2N series PLC. Sometimes some problems will occur on site after debugging, and some very simple program adjustments are required. If there is no remote debugging function, it is necessary to send people to the site to solve the problem. It greatly wastes the manpower and material resources of the enterprise, and wastes the energy of the technicians. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a method for remotely debugging a programmable controller through a telephone line, which is convenient for remote debugging, saves time and effort, and greatly re...
