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： The present invention provides a duplexed operation processor control system that includes operation processors, an I/O device, and at least one communication path that couples the operation processors to the I/O device, and at least one communication path that couples the operation processors with each other. The duplexed operation processor control system switches over either of the operation processors to be a primary operation processor that executes a control operation for a control target, and the other to be a secondary operation processor that is in a stand-by state, and the secondary operation processor snoops control data synchronously when the primary operation processor acquires the control data from the control target.

摘要： A process control system and method is provided. The system comprises a process control device for issuing a requirement command with an added address and/or group ID and a plurality of multiplexed output devices which receive the requirement command and execute a process on the basis thereof. The addresses have a same part or the group ID that are set the same for the devices. Each device compares the same part (or the group ID) with a part of a further address (or group ID) added to the received requirement command. If the same part is equal to the part of the further address, the requirement command is identified. The address is then compared with the further address based on a result of the identification. If the address is equal to the further address added to the requirement command, the process based on the requirement command is executed.

摘要： PROBLEM TO BE SOLVED: To perform the set-up through the linear regression of the transformation heat and the specific heat by superposing the transformation heat on the specific heat curve of a material to be cooled, and approximating the specific heat curve to which the transformation heat is superposed by the broken line in controlling the spray. SOLUTION: In a spray cooling equipment of a hot rolling system, a parameter generating mechanism 10 is provided with the specific heat curve generating function 7 to perform linear approximation of the specific heat using the information of the physical properties of the database 13, the transformation heat curve generating function 8 to perform linear approximation of three points of the transformation curve using the information on the physical properties of the database 13, and the specific heat curve generating function 9 taking into consideration the transformation heat which synthesizes the parameters generated by the functions 7, 8 to generate the specific heat curve taking into consideration the transformation heat. The specific heat linear generating function 7 performs the linear approximation of the specific heat. The specific heat relationship taking into consideration the transformation heat is obtained by the transformation heat curve generating function 8 to consider the transformation heat associated with the composition change in iron. Linear approximation is performed by three points using the specific heat curve 9 considering the transformation heat to perform the regression.
