In Vijeo Designer 6.2 SP11, we can't set HMIGTO IP address in the same network segment with a M340/M580 PLC when you try to connect the HMIGTO to the M340/M580 PLC via USB. As we know, the default IP address for M340/M580 PLC is 90.0.0.1, which we can't change. So we can't set the HMIGTO IP address as 90.0.0.<example>. Otherwise there will be no connection.
