(3) Reusing
Converting a standard program into a component allows the program to be
reused any number of times.
As a result, operations such as copying a sequence program and modifying a
device, which have often been required in the past, will be unnecessary.

(4) Improving quality
Converting a standard program into a component as an FB to reuse the
program allows development of programs of consistent quality, without relying
on the technological skill of the program developers.
When developers A and B are developing sequence programs for different
devices, using the same FB for the common processing enables the developers
to create consistent quality of sequence programs.
