摘要： PROBLEM TO BE SOLVED: To solve the problem that since the wiring and confirmation work of a line used to be visually performed by an operator, the oversight of an incorrect connection place occurs.SOLUTION: An arithmetic unit A3 transmits a request frame to which frame transmission information F4 has been added to an input/output device A5 as a destination. When receiving the request frame from the arithmetic unit A3, the input/output device A5 adds frame reception information F5 to a response frame to the request frame, and transmits the response frame to the arithmetic unit A3 by a 1-system line or a 2-system line indicated by the frame transmission information F4. Then, a terminal A2 diagnoses the normal connection or incorrect connection of the 1-system line or the 2-system line on the basis of a response result to the request frame received from the arithmetic unit A3.

摘要： PROBLEM TO BE SOLVED: To detect a transmission error in a communication path and to detect an error accompanying a hardware failure as well.SOLUTION: When writing data configuring a data frame to be sent out onto a communication path in a main memory, an error detection code is simultaneously added and recorded on the memory and is sent out simultaneously when configuring a transmission/reception frame thereafter. Then, after the transmission/reception frame is received on the reception side, the error detection code is added and stored in the main memory, and then error detection is performed. By the processing, failures of hardware including not only the communication path but also the memory or the like can be detected.

摘要： PROBLEM TO BE SOLVED: To prevent processing from being continued in an unstable state by immediately and reliably detecting a failure. SOLUTION: A control device includes a system-A processor collation circuit 212 which detects whether system-A information from a system-A processor 202 is the same as system-B information from a system-B processor 203 or not, and controls access of system-A access information which is either the system-A information or the system-B information to a main memory based on the detection result and instructions from the system-A processor and the system-B processor. When the system-A information is the same as the system-B information, the main memory is accessed by using one of the information specified in advance, as access information. When the system-A information is different from the system-B information, access to the main memory is prohibited. Further, whether system-A access information is the same as system-B access information is detected. An interruption is requested to the system-A processor or the system-B processor based on the detection results of logic collation circuits 213, 217. COPYRIGHT: (C)2011,JPO&INPIT

摘要： A failure is detected immediately and certainly, and continuation of processing in an unstable state is prevented. A first error detection code is generated from first information which is output as a result of execution of a predetermined program conducted by a first processor. A second error detection code is generated from second information which is output as a result of execution of the program conducted by a second processor which is configured so as to output the same computation result as that of the first processor. It is detected whether the first information is the same as the second information, and it is detected whether the first error detection code is the same as the second error detection code. Writing the first information or the second information into a main memory is controlled on the basis of a result of the detection.
