Hi!
I am new to Modbus so I would appreciate some help. I have three digital sensors that I want to use as slaves over Modbus RTU communication. The sensors are RS485, 4-wire (A and B), supply 6-36V DC, output 4-20 mA.
I can connect one sensor to a USB tool, but how should I connect three of them? I have a breadboard, would this be ok? I am not sure how to do the wiring.
