Model interface toolkit: discrete time integrator

[Helios25]

hello,

I'm currently evaluating Model Interface Toolkit to integrate some of my Simulink model into Labview. I successfully integrated basic functions, but it failed when I wanted to integrate a model containing a "discrete time integrator" (compilation is OK but output in labview is wrong : seems that the  block doesn't  react). Do you know why ?

I was looking for documentation about block compatibility but didn't found anything.

Thanks !

Posting what you have will help us help you.

Attached some screenshots. Very simple model with just a discrete time integrator block. I have well configured simulink for compilation (fixed step solver and fixed time-step + infinite simulation time) 

But integrator does not react, as you can see on the graph. If i change input it produces a step but definitly not the right integration output !
