I am trying to add an assignment on the output side of a Box but for some reason I only seem to be able to assignments on the input side of the box (as indicated by the little diamond shapes on the input side of the box).
I suspect that I might be missing something really obvious but just cant quite put my finger on it.
As the box has no FUN or FB assigned yet, outputs can't be added yet; the pins are placed automatically based on the FUN (or FB) definition. If you want the box to be as you wish (with your choice of inputs and outputs), then add a new POU-->FB (or FUN)
