  • Patent number: 11415965
    Abstract: A control apparatus records commands and information about execution time of industrial machinery. The control apparatus analyzes a program, and when a command that requires preparation time exists in the program, then calculates advanced preview command time by subtracting the preparation time from time to start the execution of the command based on the execution time previously recorded. The control apparatus outputs in advance the command requiring the preparation time when the advanced preview command time comes, so as to shorten the preparation time.
