Hi first welcome.

The flow you posted is corrupt you need to follow these instructions to post code. [How to share code or flow json](https://discourse.nodered.org/t/how-to-share-code-or-flow-json/506)

To access your 2 modbus readings you will need to join the messages, so both readings are in the same message. There is an example in the node-red cookbook [Create a single message from separate streams of messages : Node-RED](https://cookbook.nodered.org/basic/join-streams)
