PURPOSE:To increase the transmission efficiency, by transmitting the information with higher priority at the time of production with priority and transmitting other information when this information is not produced. CONSTITUTION:The measuring information AI1-AIn are fed to the input units 3-1-3-n and they are converted into digital signal at the A/D converter 5 and fed to the transmission control section 6. The output in time sharing multiplication of the transmission control section 6 is transmitted to the transmission line 8 via the modulator 7. When the monitor information DI1-DIn are present, the monitor information being digital signal is fed to the transmission control section 6 via the input units 4-1-4-n and transmitted in three successive transmission with priority. |
