Note: 1. A parent drawing is automatically called by the system. The user can execute any child or grand-
child drawing by programming an instruction that calls a drawing (the SEE instruction) in a parent
or child drawing.
2. Functions can be called from any drawing. A function can also be called from a function.
3. If an operation error occurs, the operation error drawing corresponding to the drawing will be
called.
