<p>A machine controller which can execute control asynchronously and simultaneously even when control objects compete in a plurality of jobs. The controller includes first execution means for storing commands describing the operation of a plurality of control objects as a first cooperative job and for executing them, second execution means for storing commands describing the operation of at least one control object other than a plurality of control objects governed by the first execution means as a second cooperative job and for executing them, and third execution means for storing commands for activating the first and second series execution means and for executing them asynchronously and simultaneously. The first and second execution means have a master-slave relation, and one designated as the slave refers to the output of the other as the master so as to correct the command of its own.</p> |
