Hello together,

I am facing a strange behaviour of my Simulink model. That model is comprised of a Simscape subsystem and a Stateflow subsystem. The latter is used to controll the operation mode of the Simscape model.

For a clear data transfer I implemented several data buses as Stateflow inputs and outputs. For that, I created the necessary Simulink Bus Objects and it works fine so far. But when I want to use one field of the Getoperationdata bus to describe the transition condition, the transition is not exceeded despite the condition is true (as shown in the figure below). The state Empty_Pump_Chamber remains active but should switch to Empty_Complete.

The Getoperationdata bus is implemented as an output bus. When defining a transition condition with a variable from another input bus, the model succeeds. Very strange. Even when I define a local variable, set this variable equal to Getoperationaldata.emptyComplete2 and use this new variable to state the transition condition, the model succeeds. Very strange! What is wrong?

Kind Regards!Hello together,
