Node-RED Modbus Gateway Setup on IOT 2040
Budget: $10 – $30 USD
I have a Siemens IOT2040 already running Node-RED and two flow-meters that expose their readings over Modbus registers. I need a clean flow that polls those two devices, keeps the register map exactly as it is, and republishes the same data over Modbus TCP so a Crimson-based PLC on the other side can read it without extra parsing or scaling.
There is no data pre-processing involved: whatever the meters expose is what the Crimson PLC must see. All I’m after is a reliable bridge with tidy, documented Node-RED nodes and comments so future edits are easy.
Please deliver:
• A Node-RED flow export (.json) ready for import on the IOT2040
• A brief README outlining which Serial/TCP settings to change if the network or COM ports move
• Remote hand-off support during commissioning to make sure the Crimson PLC can poll the tags immediately
If you have worked with Siemens IOT2040, Node-RED Modbus nodes, and Modbus TCP client/server setups before, this should be a quick win.
