Hello everyone,

I have a properly working model for a drive train but need some screenshots from the real time simulation - like a step response to a change in speed command. I normally observe the changes with auto-triggering option but I can’t see a proper step response in that case, just an updating screen with current values. How can I manage that, is there a way to see the scope screen over a larger time span or a way to store the data externally?

Hi,

To update the PLECS scope at a desired step response, you should set the “trigger channel”, “sensitivity”, “trigger level” and “trigger delay” parameters appropriately. To see a larger time span, increase the “number of samples” and/or “decimation” parameters. See the attached example.

This is explained in this video here – [https://youtu.be/zf6PtdZrc7w?t=246](https://youtu.be/zf6PtdZrc7w?t=246), at time stamp 4:06. Although this video is made for the TI C2000 target, the functionality is the same for the RT Box.

The scope results from real-time simulations can then be printed or exported from the File menu. Regards,Manu
