REMOTE SUPERVISORY CONTROLLER

PURPOSE:To prevent duplicate control by applying simultaneous reset to instructions of a selection section and reset to a control instruction storage of a relevant position of a storage section with the control instruction transmission or the reception from a slave station. CONSTITUTION:A control instruction storage section 31 and a control instruction selection section 32 are provided and reset of a relevant position of a control instruction storage section 31 and simultaneous reset to a selection transmission instruction are applied with the control instruction transmission or the reception from a slave station. Then distinguishment of response, no response and automatic change is implemented depending on the content of a response wait storage 44 to apply flicker display in the case of non response and automatic change and the content of the state storage 47 is revised by a reception data from a slave station. Thus, while the independence of two monitor control systems 25, 26 is ensured, the response, no response and automatic change is discriminated and the coincidence of state recognition and duplicate control are prevented.
