    Hello Ryan,

    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. The control of the bus runs from the interrupt handers. If interested, you can PM me and see if I can help you.

    Best regards,
