Sequence transitions

A transition, based on the evaluation of its expression, determines when preceding steps are STOPPED, RESET, and phases released. The transition also attaches and STARTS the phases of following steps. Transitions go active when the user-defined expression they contain evaluates to TRUE. When the transition goes active, the preceding steps are reset and the next step is started.

Item	Name	Description
	Connector	Connection point for a step. The top connector of a transition can connect to a step, a selective diverging branch, or a simultaneous converging branch. The bottom connector of a transition can connect to a step, a selective converging branch, or a simultaneous diverging branch.
	Transition name	Automatically generated transition name in the form of Tran_### where the number is incremented from 001 for each transition element you add to the equipment sequence diagram.
	Transition symbol	Identifies the location of the transition between two step elements. Each transition must be connected to a pair of steps.
	Transition expression	When editing, used to define the condition in which the transition fires (when it stops and resets the preceding steps and starts the succeeding steps).
