STRUCTURE OF CONTROL DEVICE FOR EXECUTING CONTROL PROGRAM WITH HIGH SPEED AND METHOD FOR CONTROLLING THE SAME

摘要

PURPOSE: A structure of a control device for executing a control program with a high speed and a method for controlling the same are provided to perform efficiently a control program by utilizing a low-priced operation portion. CONSTITUTION: A main operation portion performs an initialization process(S20). The main operation portion performs an initialization process of a sharing memory(S31). The main operation portion transmits initialization data to an auxiliary operation portion(S33). The auxiliary operation portion receives an initial sensor feedback value(S41). The auxiliary operation portion stores data corresponding to the initial sensor feedback value and data for the main operation portion into the sharing memory portion(S43). The auxiliary operation portion reports a state of standby to the main operation portion(S45). The main operation portion initializes an interrupt setup according to a sampling time(S51). The main operation portion initializes a data block of the sharing memory(S53). The main operation portion stores initialization data values each data block(S55). The main operation portion generates an interrupt signal in a predetermined period(S60).
