Hi,
I have a machine that talks Modbus TCP and I want to communicate to it using node-red on raspberry pi.
Is it possible to do what is shown in the picture? The register address is 40001. I have modbus TCP node installed, but mot sure how to include the bits in it to control the following.
Hello @dpatel2016 ,
Which node do you have installed? There are a lot of them dealing with modbus:
https://flows.nodered.org/search?term=modbus&type=node
I implemented also some readings with modbus. I started also with a modbus-tcp node, but was not able to get it running. Then I changed to this node node-red-contrib-modbus and now it's working (But currently I do only readings).
Did you check already the documentation of the node you are using? I found quite often also some example flows to see how it is working.
Cheers

Hi @Ranki,
I am using the node-red-contrib-modbus, but I am not sure how to include the bits with the addresses in this module.
Hello @dpatel2016 ,
it would help, if you show your configuration. I will post mine; maybe this helps you:
Cheers
