Hello i have problem with my device to connect PLC and KNX bus. First of all it don't work correct because it still is not in device mode. In ETS i made project and i cannot unprogramm this device cause it popping error "T_ack didn't get on telegram" ( i don't really know what it means). I tried to make new project and program this device on diffrent adress, but the previous project block it. Do you have any suggestions what i supposed to do?
