Modbus communication

Dear All,

I would like to ask you if there is a source to communicate with modbus RTU devices in order to ask data from specific registers. I have an arduino UNO and also some metering devices from company Schneider Electric which has modbus output. Is there anyone who already done this communication?

Thank you

hi, A good starting point might be this one Even tough the project creates slave Arduino nodes, the modbus library that I use supports both master and slave. Link to the library provided in the blog post
