 To work with Mitsubishi PLCs supporting the MELSEC protocol (the generation which is programmed in __GX Works3__ eng. tool), it must be first configured the network configuration and explicitly indicated that there will be a host (in our case WebHMI) in the network that will poll the PLC with this protocol. This is done in the visual design environment of GX Works3. You need to go to the Parameter / FX5U CPU / Module parameter / Ethernet port and 'drag' the required communication modules from the 'Ethernet Device' window: To work with Mitsubishi PLCs supporting the MELSEC protocol (the generation which is programmed in __GX Works3__ eng. tool), it must be first configured the network configuration and explicitly indicated that there will be a host (in our case WebHMI) in the network that will poll the PLC with this protocol.
