Saia® S-Engineering = Lean Engineering
How to build a building:
The combination of various
materials and methods ensures
efficiency and simplicity.
It’s the same with a
S-Engineering project:
the program commands are
the sand, and the syntax is
the cement. FUPLA pages are
prefabricated elements – but
they can be at any time bro-
ken down into component
parts, and also altered.
To see how S-Engineering works in practice:
3.
Top-down and bottom-up with a single system
There are development tools for control programs that
generate hardware-dependent, hieroglyphic-like source
code from plant displays. It often only runs on a single
dedicated controller type. This type of programming is
a top-down approach. The automation pyramid is filled
from top to bottom. Alternatively, there are systems in
which the engineering starts with the individual hard-
ware module. It continues with the realization of control
functions... and ends with the creation of plant displays
and alarm functions. The automation pyramid is filled
from top to bottom.
With Saia® S-Engineering both approaches can be used
to find the optimal, individual application. Saia® S-Engi-
neering makes top-down and bottom-up advantageous,
because Saia® PG5 basically has no hardware-dependent
source code, but rather a portable intermediate code.
Also, no tapeworm code is created from plant displays.
The intermediate step is realized through graphical ob-
jects. Thus the application is much simpler and more
comprehensible.
Saia® S-Engineering and efficiency –
analogous with building a house
To be able to work efficiently with S-Engineering
of the start of project implementation, we pro-
vide a wide range of installation templates (e.g.
DDC-Suite), graphical object libraries and func-
tion modules – they are well documented and
have been proven a thousand times over.
Anyone who wants to can use Saia® S-Engineer-
ing tools to adapt this foundation and apply their
own expertise to create modules and system
standards. Thus every customer is different from
other Saia users in terms of efficiency and skill.
