    Hi !
    Please, do you know why when I put 30s to pause between telegrams in modbus chanel, I always have a short delay:

    @Giamba It's not 30s but 0.5s. Check the read/write interval in the definition of the device...

    @Giamba The pause between telegrams can be used when communicating with devices that you send a command to make some measurement and the measurement takes some time and only after that time you can read the measured value. Then you use the pause between telegrams property.
