Xpc target data logging at different rate

My xpc model rund at 100Hz. I want to log several data for a week non stop. However, the data doesn't need to be logged every 0.01s, only every 1s.
How can I log data at a different rate than my simulation steptime? And is it possible to log so many datapoints?

Jan,
I believe that using the 'Decimation' parameter in a file scope should allow you to save a subset. In your case, set Decimation to 100 to log every 100th time step.

Eventually I would suspect the system will run out of memory for one reason or another. However, you can use a file scope to log the data to a file on the host machine. See xpc data logging on the file exchange.
I would make sure as little as possible gets logged in memory since a week is a very long time for a sim in my opinion. Good Luck.

It will repeat the values if you set it at a faster rate. If you set it for a slower rate, as you desire here, it will only pass through the value at the 1Hz rate. Go ahead and try it out in Simulink first to verify, but I know it will work as you desire.
