    摘要： A memory control unit controls writing and reading of data to the slave device according to an instruction from the master device. A bus diagnosis line is directly connected from the bus signal control circuit to a bus signal receiving terminal of the slave device without passing through the address bus and the control signal line. A bus signal abnormality processing unit compares an output bus signal output from the bus signal control circuit to the address bus and the control signal line with a feedback bus signal fed back through the bus diagnosis line to determine the presence/absence of a difference. The memory control unit elongates a bus cycle period of a bus cycle of operation being executed when it is determined in the bus signal abnormality processing unit that the difference is present.

    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.
