I need to simulate a variable from 0 to 255. And after they return from 255 to 0 and so continuously, all in simulink. I need this to simulate a variable "pv" signal processing (level control)
thanks

You want the pv value increase by 1 from 0 to 255 and then come back. What is the time vector? Every 1 second change from 1 to 2, or every 1ms from 1 to 2?

This setup should do what you need:
Create a constant (1 for example), feed that into an integrator block, then feed that into the 'mathematical function' block (set to 'mod'), and set the second input to 255.
Increasing or decreasing the first variable will control how fast your variable counts up.

Your image doesn't work, but all that warning is saying is that if you are using a fixed step solver your simulation time should be a multiple of your step time.
