1. First download Mitsubishi PLC programming software GX Developer, currently the latest version is 8.86. As shown in the following figure. Download the installation, need serial number, if you have Mitsubishi PLC can apply for serial number, if learning to use, you can search the Internet. 2. After the installation completes, opens the software GX Developer, opens the following picture to be s

(1) Network size If the network is larger, you can consider using Siemens ' blog to collect all the devices on the network. According to netizens, Mitsubishi's handling of individual equipment is relatively good, but for large-scale network, Siemens's way is indeed more humane. (2) User audience See the car electronic vflash software download firmware information is quite professional, then the PLC basically download firmware process very few hint

Today, writing a study note of the PLC, this article will introduce the most basic operation of the PLC and control instructions, this article will be directly on.1. Basic Arithmetic Operation instruction1) Integer arithmetic2) Long integer operation3) Real arithmetic、STL Programming Example (arithmetic operations for 16-bit integers)liw10//the input word IW10 load accumulator 1 Low word lmw12//the accumula

order when they are called（！！？？？ The data in the parameter table can be input/output. So the call Program name parameter ... Input/Output available)The Seven, the clock instruction uses the clock instruction can realize the call system real-time clock or sets the clock according to the need, for the control system operation monitoring, the operation record and all related real time control is very convenient. 1, read real-time clock instruction instruction Description: reads the current t

Double-click Plctask, and then cycle ticks to modify the PLC scan cycle, for example, modified to 2ms?In order to verify whether it is really 2ms, can be used in the program with the counter binding, PLC2MS scan once, the counter is also increased by 0.002 per cycle, so you can see whether the time is one second of the increase.?In TC2, you need to switch to the task configuration and then navigate to a task (default is standard only), and then modify

PLC Ladder diagram Programming exercise Traffic light ControlWhen the SW2 is off, it is easy to turn the traffic lights on and off, but when the SW2 is turned on (ie into the night mode), the red and green lights are not lit when the simulation is added.I guess the reason is that the ladder control of the one by one corresponding principle in the night mode to join the ladder after the problem, I did not find out the specific problem, did not th

PLC Ladder diagram Programming exercise Traffic light Control ?Update: Ladder diagram in the introduction of auxiliary relays, the lamp does not light the problem has been resolved, and I also found that the original ladder diagram can not achieve the counter power-off reset, and the original ladder to test the convenience of not strictly in accordance with the practice requirements set timing time, the new version of the ladder to make improv

Serial initializationD8120 Description:※ According to MD320 Communication protocol, no frame head and frame tail, then (BIT9,BIT8) = (0,0).※BIT13~15 is a set item when a computer is linked to a communication, it must be set to 0 when using the RS command.※RS485 does not consider the method of setting the control line, when using FX2N-485-BD, FX0N-485ADP, (bit11,bit10) = (in).※ If the communication parameters between the PLC and the inverter are as fol
