    Hi,

    I'm new to the Mitsubishi world, so may be anyone help me in a quick!

    I need to test a my client with the Mitsubishi MODBUS tcp. 
    To do this I would like to avoid use a real plc and use  the Gx Simulator3 that come with the Gx Works3.

    The question is: the Gx Simulator3 is capable to simulate a MODBUS tcp module?

    To be more specific I tried this:

    - created a project in  Gx Works3 with a FX5U CPU.
    - configured the FX5U built-in ethernet module with IP address of the hosting pc (also tried 127.0.0.1 with no success).
    - activated and configured the MODBUS muster to the built-in ethernet module.
    - wrote a trivial ladder program with a 1 input and 1 coil.

    I can download and run the project on the Gx Simulator3 but I cannot connect to tcp port 502 that I supposed opened by the MODBUS muster functionality of the build-in ethernet module.

    Do anyone know if the Gx Simulator is able to simulate modbus tcp functionality?

     

    Thanks in Advance

    Hi guys I need to test some code in an FX5U PLC,  but I don't have the PLC here so I'm trying to simulate it in melsoft gx works 3, but how I can test the Modbus tcp/ip if I do not have an IP address for the plc 

    someone has ever communicate both software, gx works 3 an som modbus master software ??

    For a step by step solution for MB-TCP Server (Slave):
    - Download the manual JY997D56101 to e-manual viewer.
    - Put this site-ID in the search field of the "e-maual viewer" and select PAGE in Filter section. JY997D56101-BF
    If you don't change anything in the settings here:  JY997D56101-C3.P2, all registers of the PLC are available on Modbus.
    If this is not what you want, delete the unwanted registers there:

    If that doesn't help you, describe your problem in more detail.

    Hi Dave.

     thanks for your help, the problem is that I don't understand how  Modbus TCP-IP (slave) works, for example, I'm sending some registers D1 until D34 but when I checked it on the Modbus pull it says (read error, write error), I don't know why it happened if  I'm sending the wrong type of data or is something different. 

    and also y need to receive some data from a master that is allocated in the Modbus direction 42000 - 42059 so I don't know how to set up it, if I only need to use D42000 to D42059, or how I can direct that data to a usable variable, I'm kind of confused
