    Hello Ryan, thanks for the link. So, you have checked with PC Modbus Master, that the slave address, register address, baudrate/parity/stop bits is correct?

    Please try to disconnect the 5V and supply the sensor from 12/24 V.

    What is the behaviour, please? No Modbus response from the sensor, or invalid response … we need more details to support you.

    Thanks,

    Lukas
