PURPOSE:To monitor the abnormality of a field side device during measurement control by connecting the detection terminal equipment and the operation terminal equipment of the field side to the control device of a control center side through a transmission line and providing a data processing part and a data transmission part in these equipments respectively. CONSTITUTION:While the physical quantity detected in a detection terminal equipment 2 is converted into a digital signal in an input signal conversion part 21 and the digital signal and RAS information which shows the result of a self-diagnosis are stored in an internal memory a CPU 22, the information is transmitted to a control device 1 through a transmission input-output part 23. In a detection terminal equipment 3 the output signal from the device 1 is received at a transmission input part 33 to be stored in the internal memory of a CPU 32 and outputted through an output signal conversion part 31. In the device 1 the data received through a transmission input-output part 11 is properly processed by a CPU 12 and stored in a memory 13. The data in the memory 13 is displayed on a data display unit 1a and the data from a data input unit 1b is written in the memory 13. Thus the abnormality of the field side device can be monitored during the measurement control. |
