    modbus - plc - poll problems

    I set 2 TCP modbus devices, my Barionet (Barix) and my Tbox (Servelec).

    I can access my registers (int) without problems.

    But with my TBox, the poll doesn't work by itself (set to 1 minute) and I NEED to check/uncheck the Zero-based addressing parameter to allow HS to poll correctly my unit.
    I also played with the Big-Endian values (checked/unchecked) to see the difference: none

    TBox settings

    Gateway: IP address
    TCP port: 502
    Poll interval: 1 min
    Gateway enabled: checked
    Disable Big-Endian values: checked
    Zero-based addressing: unchecked
    Retries: 2
    Timeout: 1000
    Delay: 1000
    register write function: Multiple

    TBox register settings

    Gateway: TBox
    Type: Holding Register (RW)
    Slave ID: 1
    Register address : same as Tbox modbus address
    Return Type: int16
    Signed: checked
    Multiplier: 1
    Read only: unchecked
    Enabled: checked

    Note: The Tbox and Barionet are managing correctly the registers (poll ok) and Modbus Poll prgm is accessing correctly the registers too.

    Where is my error ?
