Hi everyone, I've only just learned to use node-red a short while ago and don't know much about Javascript (but I can get AI to help).
I would like to ask a question:
I have a total of 6 data to upload to Modbus Server now, but later I will plan to upload ten and more data, if I still follow the current method, it will make the work cost more. What is the best way to increase the efficiency?
Below is my flow:

Another question is this:
Each piece of data takes up 4 bytes, am I setting something up wrong? I want to make them all consecutive.
As in the picture:
