![]() you must get the correct sample for the hardware in use. for example, FX3G_ModbusTCPServer_V100.zip or FX3U_ModbusTCPServer_V100.zip. To get started, log in to your MyMitsubishi account, search for "ModbusTCP" in the software downloads and download the correct version of sample code depending on the type of FX3 you are using. And in setting up, you are only actually going to give the module its IP Address and open 2 of it's 8 channels with TCP Support for reading/writing on the Port you specify.Īfter this has been done, the ModbusTCP functionality is handled by function block code running in the PLC that you edit and download with GX Works2. When using a FX3U-ENET, you connect the module, then must use FX-Configurator-EN to set it up. I guess this is why the came up with the -P502 version, so you could use the default Port 502.Īs an aside, FX3G-E PLC's with built-in Ethernet (in effect a built-in FX3U-ENET-ADP) also do NOT support ModbusTCP, however the FX3U-232MB-ADP Serial card does support ModbusRTU if you want a much lower cost alternative. The standard FX3U-ENET (the module that connects on the RHS Bus, not ADP version) has a limitation in that you cannot specify Ports below 1024. in any event your ADP version isn't going to work, so you will need to acquire either a FX3U-ENET or FX3U-ENET-P502. ![]() As correctly noted, the FX3U-ENET-ADP does NOT support ModbusTCP, however, you do not need to use the -P502 version either.
