Abstract: A redundant information processing system with sufficient reliability is provided at a moderate cost without any part that could be a single fault point in the system. In the redundant information processing system in which an actuator 5 is controlled based on a signal from a sensor 4, each of processing devices 1A to 1C collects command signals from other processing devices and determines which command signal to be valid according to a logical decision, for example, a majority decision. When the command signals of more than two of the processing devices including the relevant processing device which determines are valid, the command signals are output according to priority while a control information blocking signal is output to a processing device other than those which are valid.

Abstract: According to the present invention, a file recovery system is provided in which the commands for recovering files such as a historical file are unnecessitated and the recovery system configuration is independent of the host processing system. That is, since the equipment for achieving a file recovery does not have information about the location of the recovery data, information about the content of a file to be recovered is transmitted to a transmission line. The other equipments asynchronously receive the information and judges whether or not a file containing the same content exists in the own system. If its file exists, the content of the file is transmitted to the transmission line. The equipment achieving the file recovery asynchronously receives from the transmission line the file data of files such as a historical file and establishes data consistency by use of the buffered current data and the event number, thereby recovering files such as a historical file.

Abstract: A data transmission method is provided for a multi-computer system which has a plurality of computers mutually connected via a transmission line. The plurality of computers are divided into groups, with an address assigned to each group. Transmission data of a sending computer is provided with a location where the address is assigned and a location where a content code indicating the data content is assigned. The sending computer transmits the data with either the address or content code assigned, and the computers other than the sending computer decide whether or not to receive the data according to either the address or the content code.

Abstract: A method for executing programs in a distributed processing system includes executing in a plurality of first processors different programs which perform the same function. Messages, containing data representing execution result output from said different programs and attribute information indicating function to be performed by the different programs, are transmitted from the first processors to a network. A second processor then receives these messages and selects a message therefrom based on an analysis of the attribute information contained in all of the received messages. The second processor then executes an application program using the data contained in the selected message. Alternatively, the message-selecting step is made based on both the attribute information and data contained in the messages received in the second processor. Each of the messages from the first processors may include graphic image data which can be analyzed and shown on a display.

Abstract: In an information processing system having plural processing units connected through a communication medium, each processing unit operates to receive information to be transmitted from a processing portion operating in the processing unit to the communication medium and a content code predetermined according to the content of the information to be transmitted. Based on the received content code, the processing unit operates to determine an address of the destination processing unit, a sending mode used for transmitting the information, and whether or not the more reliable communication method arranged to establish a connection between the processing units is used for transmitting the information. Then, by using the sending mode and the communication method obtained as the determined result, the information is transmitted to the processing unit having an address obtained as the result determined through the communication medium.
