Title:
PROCESS CONTROLLER
Document Type and Number:
Japanese Patent JPH04195610
Kind Code:
A
Abstract:
PURPOSE:To improve the controllability by selecting and setting the best sampling period according to a total calculated arithmetic processing time and setting a clock period corresponding to this period in a real-time clock generation part. CONSTITUTION:The memory RAM of a central processing part 2 is stored with the set value of the sampling period and the set values of the arithmetic contents of blocks 1...100. When the arithmetic contents are altered, the central processing part 2 is actuated in response to a parameter setting command from a parameter setting part 3 to read in setting data, and the arithmetic contents are set according to the setting data. At the same time, the total of arithmetic processing time is calculated, the best sampling period is selected and set according to the total value, and further the real-time clock period is set. Consequently, the best sampling period corresponding to the processing time of the arithmetic is automatically set, there is no trouble, and the good controllability is obtained.
