Hi  
I tried to use these to lines from the manual but but but?

Dim ASigFilter As SignalFilter = SignalFilter.Digital Or SignalFilter.InputDim Signals As SignalCollection = AController.IOSystem.GetSignals(ASigFilter).  
Tried to find it in object browser  
What’s wrong

Its an enum, so you can’t declare an instance of it. Try

SigColl = GetSignals(IOFilterTypes.Input Or IOFilterTypes.Output)
