Thanks for your replay, jouha!

But what I want is not the Connections property.I want to make two boolean signal have a line connection between them,just like robot’s I/O signalMap.

Hi!

In order to see the connection line in the “Signals view”, you have to use interfaces for connecting. That’s actually what is happening in the background when you connect a BooleanSignal in the GUI. A one-to-one interface is created but it’s not shown, even in the Modelling context.

So, something like this:

def createInterface(component, signal):
  ife = component.createBehaviour(VC_ONETOONEINTERFACE, "interface1")
  sect = ife.createSection("section1")
  ife.IsAbstract = True
  field = sect.createField(VC_SIGNALFIELD, "field1")
  field.Signal = signal
  return ife

app = getApplication()
comp1 = getComponent()
sig1 = comp1.findBehaviour("BooleanSignal")

comp2 = app.findComponent("Comp2")
sig2 = comp2.findBehaviour("BooleanSignal")

ife1 = createInterface(comp1, sig1)
ife2 = createInterface(comp2, sig2)
ife1.connect(ife2)

Note: There’s no checking if the interface already exists, is connected etc.
