PURPOSE:To interchange audio output information and broad-band process control information through an information circuit of one loop by transmitting audio output information via a digital information circuit and then by primarily storing the information in the auxiliary memory unit of each station. CONSTITUTION:For example, if abnormality would occur in process 12b, this process abnormality is detected by CPU6b and its signal is sent to large-scale CPU1 by way of remote station 5b, digital information circuit 3 and master station 4. Then, an audio output signal corresponding to the process abnormality is extracted from auxiliary bulk memory unit 2, sent to CPU6b via the reverse route, and then stored in auxiliary memory unit 11b. After the audio output information is all transferred, CPU6b supplies the audio output information to speaker 9b via audio output equipment 8b. |
