ることを特徴とする遠方監視制御装置。 In a remote monitoring and control device that periodically transmits information between a master station device and a slave station device, when the master station device detects an abnormality in the slave station device, a specific word of the transmission format for transmitting control data is transmitted. A reset circuit provided in the slave station device detects the reset data inputted from the master station device via the transmission line, resets the microprocessor of the slave station device, and executes a retry. A remote monitoring and control device characterized by:
