I bought a Mitsubishi PLC with model no FX3G-40MT, but I don't have its software to input program. Can I have this software so I can start programming my PLC unit?
The GX Developer-FX is not available for downloading. It's a commercial application that requires an inquiry in the first place, and then the developer will give you all the necessary details in order to acquire the application and its modules, because I see it needs modules in order to operate on various models.
