Modbus RTU Rs485 with a sensor – Controllino Forums

Jul 31, 2021· There are several Modbus libraries available on the internet. Some of them work others do not work so good. For my US customer I have modified it as such that it runs Modbus on a Controllino where the Modbus is the master and the device is the slave on RS485 RTU. The library has a limited support as the device is rather basic.
