摘要： In a computer system, a device for and a method of conducting self-diagnosis of failure such as a break and a short circuit of a data communication line remove difficulty of conducting the self-diagnosis of the break and the short circuit only by driving and monitoring the data communication line by itself. For this purpose, a diagnosis module receives information necessary for self-diagnosis from a monitoring module connected to the data communication line. The diagnosis module to conduct self-diagnosis is connected via a diagnosis communication line to the monitoring module to communicate diagnosis information between the modules.

摘要： Processed results are received when processors make compatible computations on data of a common object. A computation command signal is generated and fed to the processors in response to a start signal from any one of the processors so that the processors can make computations with different operation timings. Then, the results of the computations made by the processors are compared with each other. Thus, apparatus capable of small size, high performance and safety at the same time can be achieved by the above construction using the processors.

摘要： A self-diagnosis system of a processor capable of realizing a sufficiently high processing ability for control tasks is provided without deteriorating reliability of safety controls even in complex diagnostic techniques. The self-diagnosis system is equipped with a diagnostic target area allocator for allocating a non-active area within a memory as a diagnosis-ready area, which is not used in a control task under execution by a main processor in an independent manner from the main processor; and a diagnostic executor for executing a diagnosis based upon a predetermined sequence in an independent manner from the main processor. In the self-diagnosis system, a diagnostic target area segmented from the diagnosis-ready area is selected, and a diagnosis of the selected diagnostic target area is carried out in each of diagnostic cycles by the diagnostic executor.

摘要： A multistage relay communication system 100 includes a trunk network 1 and branch networks 2 (2a, 2b), each of which includes one or more communication apparatuses 4. The communication apparatus 4 can switch between a trunk mode to operate in the trunk network 1 and a branch mode to operate in the branch network 2. In the trunk network 1, the communication apparatus 4 carries out fixing of a communication path and redundancy of data based on a path table in order to achieve real-timeness and a data arrival rate. Meanwhile, in the branch network 2, when a communication failure occurs, the communication apparatus 4 autonomously searches for a communication path and constructs a path table, in order to at least secure a data arrival rate even if real-timeness is impaired within an allowable range.

摘要： When executing sequential processing such as a ladder logic, converting a program formed of an instruction set of another processor to a program executable by an own processor in software and then conducting processing lowers the real time property. In a control system, a storage unit stores a program for the own processor and a program for another processor. A processor reads data from the storage unit, executes processing described as a program, and gives an instruction to change over a method for acquiring data from the storage unit, to a conversion instruction unit according to data contents. A changeover unit is connected to the storage unit directly or via the conversion unit to change over the data acquiring method according to an instruction from the conversion instruction unit. The conversion unit converts data read from the storage unit to data executable by the processor, according to a conversion scheme.

摘要： A processing unit is connected to another processing unit through a system bus composed of serial signal communication line and synchronization signal communication line to be able to communicate therewith. When an operation unit detects abnormal state in the processing unit, the operation unit supplies notification of detection of the abnormal state to synchronization unit. The synchronization unit transmits the received detection notification of abnormal state to the other processing unit through the synchronization signal communication line. Conversion unit receives parallel communication data from the operation unit through important signal line instead of general signal line and converts the received parallel signal into serial signal to be transmitted to the other processing unit through the serial signal communication line, thereby soundness among processing units connected to the system bus is ensured when the system bus is configured to attain serial communication.

摘要： A communication device reduces a processing time required at the time of mutually converting different wireless or wired communication protocol and improves a real-time property. The communication device includes two or more communication units which communicate with two or more external devices and a communication controller which processes communication data. The communication controller has table information that associates a communication path, a type of the communication unit, and conversion-info, and an input and output unit that inputs and outputs the table information. According to the added conversion-info, a conversion unit sequentially performs various conversion processes (protocol conversion, routing, communication quality evaluation, fragmentation/integration of communication interface, fragment/defragment process, frame multiplication/integration, and frequency setting).
