Dear Community,

I'm controlling the simulation course of a simulink block diagram for control system design purposes. I do this through changing a property called 'SimulationCommand' to 'pause', 'continue', and 'start' values. As the script file immediately runs the next command line after the 'set_param' command, I couldn't plan my control loop. I was wondering if there is any way perhaps using the 'wait' command to prevent the script from running until the simulation result of the control sample is arrived. That is to wait until the simulink engine is paused by the 'Pause Block' which is defined inside the model.

This is, somehow, a following question for the previous discussion here , which has been left open.

pouya: Could you please elaborate on why S-functions (as suggested on the previous thread) do not solve your problem?

Ms Govind: I know that s-functions would solve my issue but I don't have enough time to convert the codes I've written into an s-function format. They like 15 auxiliary functions and 65 parameters from varied classes.

I'm wondering why is that m-code/simulink interaction for if s-function is performing the best. I wish there is a way. If only the 'SimulationCommand' property was not write-only I could solve my issue. Is there any way to find out about simulation status of a simulink blogdiagram? I mean weather it is running, initializing, or is paused?
