摘要： In a control apparatus which transmits/receives data from a central processing unit via a serial transfer channel to a communication control unit, and groups/distributes data of input/output units from the communication control unit via a parallel transfer channel, the control apparatus initiates a diagnosing unit of the parallel transfer channel in response to an instruction issued from the central processing unit, and diagnosis the input/output units subsequent to the diagnosis of the transmission channel. Data input/output timing of the input/output unit is also instructed from the central processing unit, so that the central processing unit can suppress lowering of response speeds caused by the diagnoses, and can maintain the periodicity of the data input/output.

摘要： A control apparatus has a communication control unit communicably connected to a first communication channel, at least a portion of which constitutes a serial transfer operation. The communication control unit transmits/receives information with respect to an equipment under control via a second communication channel, a portion of which constitutes a parallel transfer operation. The apparatus comprises: a communication channel diagnostic unit for diagnosing an abnormal event such as an open and stuck-at of a parallel transfer portion of the second communication channel under such a condition that a data transfer operation in the second communication channel is interrupted. A signal for instructing an initiation of a diagnosis via the first communication channel is transmitted to the communication channel diagnostic unit.

摘要： PROBLEM TO BE SOLVED: To make both accurate control on the same control device and control for information such as communication be compatible. SOLUTION: The controller 1 of the hardware part of a control device is configured to perform a control arithmetic operation from a signal from an input/output device 3, and to output a control arithmetic result through an input/output device 3 to a process 4, and provided with a timer part 17 to be excited in a fixed cycle. A software part is provided with a processing part 55 for an information; a processing part 54 for control; and an interruption management part 53 for switching the processing part 55 for information and the processing part 54 for control. Every time a timer 17 is excited, the interruption management part 53 executes a processing part 54 for control by interrupting the execution of the processing part 55 for information, and resumes the execution of the processing part 55 for information when the execution of the processing part 54 for control ends, and switches the processing part 55 for information and the processing part 54 for control.

摘要： PROBLEM TO BE SOLVED: To solve problems of complication of devices and inhibition of response speed/input and output on-time property in attainment of function security in a programmable electronic device, whereas diagnosis with a software program must be performed for cutting a closed loop which needs diagnosis for own accidental failures of a diagnostic device, and microprocessors must be consequently mounted not only on a logic arithmetic device but also on an input and output device to execute a diagnostic program.
SOLUTION: In the control device for transmitting and receiving data from a central arithmetic storage device to a communication control device through a serial transmission line, and collecting/distributing data of an input and output device from the communication control device through a parallel transmission line, a diagnostic device for the parallel transmission line is started according to instruction from a central control unit, and diagnosis of the input and output device is performed successively to diagnosis of the transmission line. A data input and output timing for the input and output device is instructed from the central arithmetic storage device. Accordingly, on-time property of data input and output is kept while suppressing reduction in response speed by diagnosis.
