    Many thanks again – Happy new year Mikhail!
    1.http://easymodbustcp.net/en/ – free app.
    2. I will try that.
    3. If I can write commands to turn on and off bits, write values to registers
    I should be able to write the access code.

    If I do not sent the access code – it fails as with Rapid Scada
    Tx: 00 09 00 00 00 06 01 03 00 0D 00 01 – read holding register
    Rx: 00 09 00 00 00 03 01 83 02 – rejected
    Tx: 00 0A 00 00 00 06 01 03 00 0D 00 01 – read holding register
    Rx: 00 0A 00 00 00 03 01 83 02 – rejected
    Tx: 00 0B 00 00 00 06 01 06 18 C2 00 00 – write single register
    Rx: 00 0B 00 00 00 06 01 06 18 C2 00 00
    Tx: 00 0C 00 00 00 06 01 03 00 0D 00 01 – read holding register
    Rx: 00 0C 00 00 00 05 01 03 02 01 69 – correct response!

    Rx: 00 06 00 00 00 05 01 03 02 01 69
    My problem is I am unable to send the access code – my error is either Output channel number 1 but where do I put “Command number” and set the value 0 (zero).
