Thank you for your input but I think I need more guidance, for communicating a digital input device to RS485 and reading the data in Node-red.
Also I had troubles in assigning the servers in some Nodes (Modbus Read)

As a beginner in Revolution Pi Connect S, I am working on a project where I need to read a digital value of temperature sensor module connected to digital converter, with converter connected to RS485 socket of Rev Pi using Node-Red
