Hi friends hope all of you are doing well. I have Mitsubishi FX3U plc communicating with Mitsubishi VFD over rs485 using FX3U-485-ADP-MB card and plc also communicating with Mitsubishi hmi over RS422 port. I want to communicate this PLC with nodered to read Data Register eg.D 8415, D8416....etc as attached in ladder program and screenshot attached for hardwware. Please help me how to set up communication with Node-Red and Read PLC Data Registers. Thanks

You best bet would be to add an Ethernet card to it an use the [node-red-contrib-mcprotocol (node) - Node-RED](https://flows.nodered.org/node/node-red-contrib-mcprotocol) nodes
