How to use a scheduler in System Composer?

I would like to use a scheduler in System Composer. I have 4 different taks (T1,T2,T3,T4), , each one with its specific periodicity. I would like to know how to create a scheduler to define the different priorities and periodicities of the different tasks.

Hi @Amine,

To use the schedule editor, first, ensure that your architecture model was created using the "Software Architecture Model" template:

In the software architecture, you can launch the schedule editor from the Design section of the MODELING tab. Note, You can also specify periodicity in the Functions Editor.

This scheduler is for simulation only. If you are looking to generate code from your scheduler, you can include the software architecture as a model reference in simulink and then hook in a scheduler created in simulink or stateflow. Here is an example:

Hi Josh. Thank you very much for your answer. I have well accessed to the schedule editor. However, it is for the next steps that I am stucked. I don't know what to do when I am in the Schedule Editor. I found videos on the subject but every time they have already some diagram in the sceduler while I have nothing

The schedule editor shows existing functions that can be run. If it is empty, then you first have to create functions or link your components to simulink behaviors.

Here is a link with more information on authoring functions:

If you already have linked simulink behaviors and the schedule editor is blank, try updating the diagram (ctrl-d).

Okay I have linked my components to Simulink behaviors and now it is working. Thank you very much!
