Abstract: In the conventional distributed control system, since each control device updates the data area at a timing when a control packet is received, in a case where there is a difference in communication delay between the control devices or in a case where the communication delay includes jitter, it is difficult to match the contents of data in all the control devices in a case of focusing on a certain moment during system operation. Therefore, depending on the start timing of a control application, the control application operates on the basis of different data between the control devices, thus limiting control performance improvement. Accordingly, time slots on the network are allocated according to the result of a calculation unit, and a cyclic memory synchronization update unit synchronizes the timing of reflecting data in the input/output and the cyclic memory and the timing of using data of a cyclic memory.

Abstract: A program editor creates a program-edit screen for a control system based on element data for representing circuit elements and operators and their attribute values. Here, the circuit elements and operators are components of sequential programs which constitute functions of the control system. The program editor which edits the element data on the created program-edit screen judges whether the data for representing the circuit elements and the operators is protected-function data or non-protected-function data and displays assembly sets of programs for implementing predetermined functions constituted by circuit elements and operators to which accesses are authenticated on the program-edit screen in a display mode different from those of the other assembly sets.

Abstract: 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.
