Latest Patents

Yasuhiro Nakashima holds a patent for a "Process control simulator and process control simulating method." This invention provides a process control simulator designed to efficiently debug a plant control system. The system utilizes a computer that stores simulated data generated by a model executing part in a time-series memory area. A programmable controller halts input from the input-device interface upon receiving a virtual input/output request. The virtual input/output processor then sets simulated data from the computer's time-series memory area to that of the programmable controller. The program executing part transfers simulated data to a memory area that matches the resolution of the program execution's arithmetic operation period and executes the program. The control output resulting from this execution is fed back to the model executing part of the computer, which calculates the simulated data as process value at that timing and stores it in its time-series memory area. Yasuhiro Nakashima has 1 patent to his name.
