Function Block Diagram (FBD) base
The Function Block Diagram provides the base for which all programming actions for the
α
2 is
performed. Both the
α
2 controller and the AL-PCS/WIN-E software use the FBD base. The
FBD base contains a Title rectangle on the top, Input rectangles on the left and Output
rectangles on the right. The FBD base is also known as FBD wiring area. All the components
should be placed only within the FBD base rectangle except for the input and output signals
which can be placed in the FBD wiring area or in the Input or Output rectangles.
