SITRAIN Training for Automation and Drives * * * %IX2.4%IX2.3 Extract from IEC : Transitions A transition represents the condition whereby control passes from one or more steps preceding the transition to one or more successor steps along the corresponding directed link. The transition shall be represented by a horizontal line across the vertical directed link. The direction of evolution following the directed links shall be from the bottom of the predecessor step(s) to the top of the successor step(s). Each transition shall have an associated transition condition which is the result of the evaluation of a single Boolean expression.
