Behavior of the Veristand engine and inline model custom devices

Hi,

I just want to report a dubious behavior of the veristand engine in case of an "Inline Model" custom device in the "Parrallel mode":

I notice that the number of PCL's iterations between the reception of inputs and the update of outputs, is impacted by the properties "Scalable" and "Faultable" of the channels:

With the two properties set to "False", the intputs and outputs are updated on the same iteration of PCL.

But if I set one property to "True" then the outputs are updated on the next iteration of PCL.

And if I set the two properties to "True" then the outputs are updated two iterations of PCL later !

This behavior induces a device control instability as the custom devices outputs are transfered too late.

The workaroud is of course to set the properties to false.

Nevertheless I also wonder if this working is the same for the other tasks like the models tasks ?
