With Saia® S-Energy
Expanding energy management and linking
it with automation
Even though at the outset the simplest available
system can ease implementation, the gradual intro-
duction of energy management must not lead to a
dead end or create an obstacle to further expansion.
In this initial phase, all the relevant energy users
are gathered. Initial savings result from the identi-
fication and elimination of malfunctions as well as
behavioral changes. If, for example, specific energy
values should be used to calculate manufacturing
costs, affect finance and accounting, or if through
automation further efficiency gains are made, then
simple measurements are no longer enough. It is
a significant advantage when the system installed
has its own interfaces and allows for expansion. S-
Energy is a solid technical measurement basis for
the further development of energy management.
Collected energy values can be made available in
Excel-compatible CSV-data or via SQL database
for further analysis and processing. In automation
projects, S-Energy shows the extent of its PLC-tech-
nology heritage: The programmer is free to design
and adjust the user interface and function of the
S-Energy Manager. A data exchange with other con-
trollers is ensured by the support of common bus
protocols. It is no coincidence that S-Energy fits
seamlessly into the Saia® PCD automation world.
Thus an action is recorded at the control level from
pure measurement and observation. Thus the en-
ergy management develops from a pure measuring
and monitoring to a complex control system. What
might begin as a simple inventory opens the door
for automation projects for better energy balance,
eventually leading to reduced energy consump-
tion, lower costs, less CO
2
and cleaner consciences.
Although Fukushima is now out of the media glare
and has adopted an attitude of «keep calm and carry
on», it is true that anyone who ignores the subject of
energy today is storing up problems for tomorrow.
Evolutionary steps
rather than invest-
ment jumps.
Implementation of
energy management
in small, manageable
steps, with a negligible
limited risk leads to
concrete results. First
savings set up step by
step. A controllable
technology, such as
S-Energy allows safe
walking through the
learning curve for
operation with its own
staff.
