.Modelica_StateGraph2.LoopBreakingTransition

Information

Every loop in a StateGraph2 model needs to have at least one delayed transition. If this is not the case, a delay needs to be introduced at one transition of a loop. The "LoopBreakingTransition" is designed to replace an (immediate) Transition by a Transition that fires immediately, and then waits in an internal step for the defined delay time. The semantics is therefore slightly different if a Transition with "delayedTransition = true" is used. In the latter case, the transition only fires after the delay time and the fire condition must remain true during this time period.

A LoopBreakingTransition is just a convenient short hand notation for the combination of a Transition, a Step, and a delayed Transition as shown in the following table:

LoopBreakingTransition	Equivalent system

In the following table different configurations of a LoopBreakingTransition are shown:

Parameter setting	Icon	Description
Default transition		The LoopBreakingTransition fires when the preceding step is active and the expression "condition" in the parameter menu is true. After a "waitTime" (here: 0.001 s) the succeding step is activated.
use_conditionPort = true		The LoopBreakingTransition fires when the preceding step is active and connector "conditionPort" is true. After a "waitTime" (here: 0.001 s) the succeding step is activated.
use_firePort = true		Connector "firePort" is true when the LoopBreakingTransition fires and the internal Step of this element is activated. Actions may be triggered, e.g., by connecting block MultiSwitch to the firePort.
