Web HMIs have conquered the world of automation
Since 2011
The Saia®Web-HMI-world «goes fully mobile» and starts with functional-
HMIs
At the Light + Building Fair in April 2010, we were the first company to offer the
technology for iPad. The HMI application on the iPad impressively demonstrated
the openness and communications capacity of Saia® PCD automation devices. In
the meantime, tablet computers and smartphones have become ubiquitous they
are in every shop and can always be found online.
Since April 2011, the Saia®Micro-Browser-App can be downloaded from the iTunes
store and is fully established as a product. The Android world will soon follow. For
managers, operations supervisors, service personnel or caretakers with Saia®Web HMI technology all stakeholders
have the Saia® PCD automation world in their pockets, and always under control.
In addition to «going mobile», 2011 saw the successful beginnings of a brand new category of device the Saia® func-
tions-HMI. They offered everything that the Saia®Web-Panel offered, an in addition had a fully documented applica-
tion preinstalled: take it out of the box, plug it in and it’s ready to use. Web applications run through Saia®Micro-
browsers on all platforms. An application can be used by different target groups simultaneously and in any location.

Consistent implementation of lean automation
More automation with fewer qualified personnel
for minimal cost those are the aims of lean automa-
tion. With Web-HMI it works really well. It was even
better in this case because additional costs in the
design were taken into account systematically,
as the following example from the 5.7" display
module technology range demonstrates:
Web-HMI technology is lean in its basic design
In a client-server architecture, a client (here:
Touch panel) can access any connected controller
remotely without additional cost. That reduces the
engineering cost, so fewer HMI devices are needed
in a building. What’s not there costs nothing and
can’t go wrong! If a permanently installed industrial
panel is not required, standard PCs and /or mobile
devices are used. Regardless of the end device,
all clients are on the same level. In case of failure,
the client hardware can easily be replaced without
the need for proprietary software. That means less
service costs and no dependence on individual
manufacturers.
Features of the market standard
with the 5.7" touch panel
We produced the first 5.7" Saia®web panels with
microbrowser technology in accordance with the
market standard: with color-STN LCD in ¼ VGA
(
QVGA) resolution (320 × 240 pixels) with CCFL
Backlight. But the low resolution made it virtually
impossible to display graphical assistance, a user
guide or parts (machinery/ equipment) for the user
on the touch screen.
More value vs additional costs

Nor did it make sense to show trending curves
with QVGA resolution. Service personnel and system
operators would always need an additional tool for
system optimization and error analysis.
