<p>PURPOSE:To repeat the control period for the whole of the system at a constant period to improve controllability, by providing a timing system, which controls individually periods of respective processing devices, to cope with variance of respective control periods. CONSTITUTION:Plural processing devices 3-5 do not communicate with one another directly, and a timing command 2 from a timing system 2 is used as a trigger signal to control respective control objects 7-9 of a control object system 6 individually. Control periods of plural processing devices 3-5 are controlled individually by the system 1 so that control periods of processing devices 3-5 are integral mutliples of the fundamental period, respectively and ratios of respective control periods become integers, thereby coping with variance of respective control periods. Thus, the control period of the whole of the system is repeated at a constant period to improve controllability.</p> |
