装置。In a remote monitoring and control device slave station equipped with a D/A converter that outputs an analog signal, the input of the D/A converter is disconnected from the normally connected reception data bus at a certain timing, and a predetermined analog signal is output. The output of the D/A converter at that time is input to the A/D converter provided for measurement, and the digital output value at that time is used to set the D/A converter. A remote monitoring and control device characterized in that it is capable of detecting a failure of a /A converter.
