Hello Cédric, 

The max integration time interval can be set using the scs_m.props.tol 
vector which is documented [1]. 

To set a specific parameter values, define a variable in the diagram 
context which is used as dt then set it the right value the 
scicos_context struct. 

For more information on setting variable values, take a look at the 
"Optimization of a PID" [2] wiki page.
