  • Hi

    I've been having a recent issue and I'm in the need for some help, if there's someone who can help it will be greatly appreciated.


    I've set up a DGBox and I have 1 serial modbus RTU line connected via one of the USB ports using an RS-485-USB converter ( modbus devices I have connected are a Socomec Diris A10 electricity meter ( and also a Novus Digirail-4C Digital Input Counter (

    When the Data Source is enabled and i have only the electricity meter connected i get readings back, although i always get fault messages like 'Feb 12 16:57 - No response from slave 1 (8024 occurrences, most recent at 07:31:18)'. When i have only the digirail connected i get a similar outcome. But when i connect both i get no readings at all, just fault messages on both devices.

    Data Source Configuration is as follows,
    Bit Rate, 9600
    Flow control in, none
    Flow control out, none
    Data bits, 8
    Stop bits, 1
    Parity, Even
    Encoding, RTU
    Echo, Off
    Concurrency, Slave
    Timeout, 500 ms
    Retries 3

    A10 Meter (26 data points)
    slave address, 1
    baud, 9600
    parity, even
    stop bits, 1
    data bits, 8

    Digirail (2 data points)
    slave address, 11
    baud, 9600
    parity, even
    stop bits, 1
    data bits, 8

    I did have slave addresses of 1 & 2 but that also did not work so i changed one of them to see of it helped, but it did not. Devices are being polled at a 30 seconds frequency.

    I really don't know what is going on.

    Hope you can help me out.
