Chapter 15 Continuous Function Charts 15.2.10 Changing the Order in Which Objects are Executed The numbers in the upper right corners of the objects in a continuous function chart indicate the order in which the objects are executed. If users want to change the number in the upper right corner of an object, they can right-click the object, point to Execution Order on the context menu which appears, and click Up , Down , Front , Back , Insert After , Data Flow , or Topology . If Data Flow is clicked, the order in which the objects in a continuous function chart are executed will be determined by the data flow of the objects.
If Topology is clicked, the order in which the objects in a continuous function chart are executed will be determined by the relative positions of the objects. If the execution order is changed, the result would also be different. The auto-arrange button on the tool bar is suggested to use for users who are not familiar with the order. 15-21
