Reply To: Modbus TCP with node-red

Michael when you install using npm it takes the latest npm package.
node-red-contrib-modbus has been completely re-written and has a number of discrepancies which means it won’t run on AEP.

I think I used version 0.7.0 which only does modbus TCP you wan’t get RTU working on AEP.

To install old npm versions use the following
npm install node-red-contrib-modbus@0.7.0

To see a list of all versions
npm view node-red-contrib-modbus versions

I have friend that is running 3 or more AEP’s using node-red-contrib-modbus I will ask what version they got working.
