    Hello acansoy,

    First open Connection Destination. We choose - Direct Connect to CPU. We choose Adapter - your Ethernet Adapter. By default IP PLC is 192.168.3.250.

    Hello Mikax,

    I checked the available versions of Medoc and it turned out that I also have only 2.40. There may be missing parts of the program because the ranges for M, L, T, D are not correctly defined. For example, the range of M e 0-999 and in the program we have M1201.

     

     

    There are cases where the PLC is A2S and the software recognizes it as another. Do you have an extra memory extension?

    Hello @DanW

     

    I share your opinion on Modbus communication. My client insisted on finding a solution for controlling these 34 frequency inverters on a serial port.

     

    The only possible solution, in my opinion, is to allocate these inverters to the four CH1 - CH4 serial ports and to use the Mitsubishi protocol for communication with inverters.

     

    Still, it is a machine, not an experimental set-up.

     

    Thanks for your advice.

     

    The best regards,

    Hello,

    It is necessary to manage 34 inverters via serial communication RS485. If a Modbus protocol is used according to the documentation, only one RS485 channel can be master. Then the maximum number of inverters will be 32. Can anyone share their experience on this case?

    Thanks in advance to all those who participated!

    Hello Zubair136,
    There is no problem for a display to work with two controllers. Which model is HMI Weintek?
    Normally, we have several serial communication ports - COM1 and COM2.It is also possible to add an Ethernet module to the FX2N.
    Good luck!

    Hello,
    Do the cables you use have a shield? If yes, did you connect it to the SLD terminal in module?     Check the connection of PLC terminal PE to the cabinet.

    The best regards.

    Hello Ulrik,

    MELSOFT iQ Works is an integrated software suite consisting of GX Works3, GX Works2, MT Works2, GT Works3, RT ToolBox2 mini, FR Configurator2 which are programming software for each respective product. Integration is further enhanced with MELSOFT Navigator as the central system configuration incorporating an easy‑to‑use, graphical user interface with additional project-sharing features such as system labels and parameters. The advantages of this powerful integrated software suite are that system design is made much easier with a substantial reduction in repetitious tasks, cutting down on errors while helping to reduce the overall TCO. (http://www.mitsubishielectric.com/fa/products/sft/melsoft/smerit/iq_works/index.html#pageUnit02).

    GX Works2 supports FX-1N. Look @Gambit post. What is the problem?

    GWWorks3 has to be the worse software on the market. I program quite a few plcs and this is the worse. What a waste of my money. Help files are no help. Took hours just to find out how to add a timer. Still can not get around the software. Wow, with all the different plcs on the market why would anyone want to use Mitsubishi? AT 650 bucks for software, not a good option.

     

    I am going to rip out the plc and replace it with some other brand. It came  equipment from China.

    You're probably joking!
