I created two models A and B, in model A, its algorithm requires some parameters from model B to trigger a conditional event, vise versa for that in model B. So how do I gain the access to the parameters from another model and use that to trigger the events from the current model?

i.e.
model A
discrete x;
Boolean conditionA;
algorithm
when pre(conditionB) then
x := 3
end when
end A;

model B
discrete y ;
Boolean conditionB;
algorithm
when pre(conditionA) then
y := 5;
end when;
end B;

in this case, the model A need access to the Boolean variable "condition" in model B.

not sure if this is an appropriate example, please help me. thanks in advance!
