FB_HomingBlockBaseHmi

FB_HomingBlockBaseHmi 1:

This class extends the basic parameters of the homing type referencing methods specifically for applications with an end stop.

FB_HomingBlockBaseHmi 2:

Class is abstract

Since the class is defined as ABSTRACT, the class cannot be instantiated and must be implemented using inheritance.
