摘要： It is possible to leave records with which analysis of a cause can be efficiently performed when a trouble occurs in an observation target system and realize reduction in the size of the records at the time of recording. The present invention is proposed as a log recording apparatus. This log recording apparatus is provided with: a cell number storage unit to store a cell number table with cell numbers, each being data for identifying a cell number from a state/event combination; a cell number generation unit acquiring data indicating an event and a state from an observation target system, to determine a cell number corresponding to the event and the state with the use of the cell number table stored in the cell number table storage unit and the data indicating the event and the state; a log data generation unit to generate log data which includes the cell number determined by the cell number generation unit; and a log data recording unit to record the log data generated by the log data generation unit.

摘要： An object is to provide a redundant supervisory control system and a redundancy switching method thereof. In the redundant supervisory control system, remote I/O apparatuses are less likely to be inaccessible, even in a case where failures occur in plural locations. Thus, the reliability of the system is enhanced. The redundant supervisory control system including a plurality of first loop interface units in each of a pair of controllers, second loop interface units, and communication cables each connecting the plurality of first and second loop interface units with one another in a circular loop. The redundant supervisory control system is configured by connecting the controllers and the remote I/O units to one another in a plurality of loop networks. In a case where abnormality in the loop networks is detected by use of received data in the networks, the first and second loop interface units that can perform normal reception are automatically selected.
