Posted 4 Jul 2022 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 Luciano. 1 person likes this Share this post Link to post Share on other sites
Posted 4 Jul 2022 Don't think the simulator support modbus but setting the FX5 up to be a modbus server is easy. Share this post Link to post Share on other sites
Posted 4 Jul 2022 Hi Gambit, Yes, I setup FX5 to be a modbus server, its easy. But when I download to the Gx Simulator3 I cannot connect the FX5 using modbus. I supposed that the simulator doens't support modbus but I don't find any documentation on this. Share this post Link to post Share on other sites

I'm trying to do the same but I didn't find any way to do that. Share this post Link to post Share on other sites
