QtModbus Help

Are you making sure that you call the read function only after the device object has signalled it is in connected state?

I hope yes but... I try to check modbusDevice->state(); and in effect it is afer connection in QModbusDevice::ConnectingState. Maybe i need other instruction for connection, or maybe there is a problem in localhost slave?

Thanks for reply!
