I link my TPsVar to the provider with the AddVariable method of the AddressSpace.
When I change the value through the Value property of my TPsVar at my provider runtime, the value is changed but it’s not propagated to the rest of the clients connected.
I search through the reference and I see a ChangeSignal property. It seems that this sginal is not triggered when you change the value of your TPsVar directly in the provider program but if you change the value through a client, very body that is connected can see the new value.
How can I trigger the ChangeSignal when I modify the value in my provider program changing the Value property of my TPsVar?
Best Regards.

ChangeSignal is emitted whenever the Value property changes. It should not make a difference where the change is coming.
If you look at the source of the Simulation Server, it is changing the values similarly: For example (SinusoinVars.pas):
var
I: Integer;
Amplitude: Double;
CosPiT: Double;
begin
PsBool1.Value := not PsBool1.Value;
CosPiT := (Cos(Pi*T/180)+1)/2;
with PsFloat1 do
begin
Amplitude := RangeMax-RangeMin;
Value := Amplitude*CosPiT;
end;
