I'm using the FMU SDK to test the generated FMU on OM.

I test this example :

model DiscreteTimeObj
    parameter Real sample_interval = 0.1;
    Real x(start=5.0);
    Real y;
equation
    der(x) = -x;
    when sample(0, sample_interval) then
        y = x;
    end when;
end DiscreteTimeObj;

using the command (binary of the FMU sdk to test the fmu) :

fmusim_me.exe DiscreteTimeObj.fmu 1.0 0.01

that is to say with startTime = 0.0 stopTime=1.0 with a time step imposed to 0.01.
When I plot y, it remains constant to 5.0. This example works on OM : y decreases and has constant values
in the intervals of length 0.1.

Is it a limitation of the generated FMU that doesn't support the directive sample or is it the code of
the fmu testing program work ?

Thank you for the help.
