摘要： A system structure recognition method for a multiloop transmission system for recognizing the system structure of a transmission system consisting of a plurality of loop transmission lines, a plurality of devices connected with each of a plurality of transmission control devices disposed on each of the loop transmission lines, and relay terminals connecting the loop transmission lines with each other includes a step of sending the message to the loop transmission lines after having added an address to the data portion of the message, when a message for system recognition reaches each of the transmission control devices from the loop transmission lines and a step, in which, when the message for system recognition reaches one of the relay terminals from one of the loop transmission lines, the message is sent to the other loop transmission line after having inserted a flag representing a relay of the message between different loops in the data portion of the message for system recognition.

摘要： Attribute information of programs developed by processors in a distributed processing system include I/O data for defining I/O operation of the programs, which is given in a program description form. A correlation of the programs is checked based on the content of the attribute information. Program generation information, program content information and program modification information are added to the sharedly developed programs and they are updated in the course of development.

摘要： A distributed processing system comprises a plurality of processors (11 to 14) which are connected to a common transmission line (1). When a program constitution in anyone of the processors (11 to 14) has changed, a message to this effect is broadcast to the common transmission line (1). When the message has been received from the common transmission line (1), information on programs stored in the respective processor (11 to 14) is broadcast to the common transmission line (1), whereby the messages indicating the program constitutions in the individual processors (11 to 14) are automatically broadcast onto the transmission line (1) at the changes of the constitutions of programs. If in such a system a series of processes are executed by a plurality of programs, the relation among programs according to the flow of the series of processes can be recognized using information on the input/output data of each of the programs.

摘要： 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 (12) for achieving a file recovery does not have an information about the location of the recovery data, an information about the content of a file to be recovered is transmitted to a transmission line (1). The other equipments (12) asynchronously receive the information and judges whether or not a file containing the same file exists in the own system. If the file exists, the content of the file is transmitted to the transmission line (1). The equipment (12) achieving the file recovery asynchronously receives from the transmission line (1) the file data of files such as a historical file and establishes data consistency by use of the buffered current data (504) and the event number (1004), thereby recovering files such as a historical file.

摘要： In a distributed processing system which distributively performs a series of processes for a work at a plurality of processing units (2i) connected to a common transmission path (3) and having a circuit (2i, 1i) for transmitting information from a processing unit to the common transmission path, a circuit (2i, 1i) for receiving from the common transmission path the information required for the processing of a program stored in each processing unit, and a circuit (2i, 1i) for detecting if all the information required for the processing of the program has been collected, performing the processing of the program using the collected information as input information for the processing and transmitting the processed result data to the common transmission path, a method of managing programs includes the steps of: transmitting a program stored in each processing unit or a program newly generated or modified by each processing unit, together with program generation information, to the common transmission path; and discriminating a difference between generations of a plurality of developed programs.

摘要： PURPOSE:To improve soft productivity by updating the module constitution of a whole soft system each time respective soft modules are prepared and executing the design and development of the soft module. CONSTITUTION:When the internal processing of the soft module, for which input/output data are determined, is designed, the matching of the contents of message data is checked between the soft module and the already prepared module each time the soft module is prepared. Next, the possibility of matching and separation for the message data is displayed and relation between the soft module, which prepares the message data, and the soft module to use the message data is checked. Then, by displaying the possibility of unification and separation for the soft module, the number of the message data, which constitute the whole distributed soft system, and soft modules can be arbitrarily adjusted.

摘要： In a system which includes a plurality of subsystems (11-14), and a transmission medium (1) for coupling them, and in which a token (301) is sent to the transmission medium, whereby the transmission medium is occupied; a transmission control method is characterized, at least, in that each of the certain subsystems appends a code (FC) indicative of a function of certain data to the data and sends the resulting data to the medium, and that the subsystem receiving the data refers to the code indicative of the function of the data, thereby to independently judge whether or not the data is to be accepted into the own subsystem.

摘要： Programs in a plurality of processors connected through a common network are started when a plurality of data necessary for starting the program are received from the network. When the processor receives data from an external equipment, it adds the event number to the data and sends it to the network, and each processor determines whether all data necessary for starting the program in itself have been received and checks the relation among the received data by comparison with the event numbers of the received data.

摘要： In a distributed processing system where a series of process is carried out by distributed processors connected through a network without provision of a control processor which controls the overall system, an arbitrary processor generates test information and the processors, each having a memory for storing a program to be tested, decide whether or not the program is to be test-run in accordance with the test information and, if test-run is carried out, send out the result of the test-run program into the network when necessary.

摘要： Programs within a number of processors (101 to 108), which are connected to each other in a distributed processing system, are started when a number of data sets is present. If a processor receives data from external equipment (161), it stores data with an event number which is assigned to the input data on the basis of the content code (CC), and determines, by comparison with the event number in a buffer of the processor, whether a predefined number of data items with event numbers has been received.
