Successful generation change at the automation level
The determining factor was not to start from scratch
but to create a functionally compatible replacement.
Existing application programs can be transferred for
modification and extension with Saia® PG5. Thus, the
further development of the controller range is not
yet complete. In this article you will learn what hap-
pens next and where the new controllers are imple-
mented.
The new
Saia
®
PCD
Controller generation
Fully compatible with the past, and ready for the
future.
In 2011 Saia-Burgess reached an important milestone – the entire Saia®PCD controller
family was renewed. 10 years ago, the basic equation of Saia® PCD = PLC worked fine,
but the formula for all controllers today is Saia®PCD = PLC + (Web + IT).

Combines up to 50 × more processing power
with web and IT technology
From the small Saia® PCD1 to the largest Saia® PCD3
controller, all Saia® PCD controllers are now avail-
able in modern technology and with innovative new
features. With their rapid ColdFire processors, they
have up to 50 × more computing power than the old
Saia® PCD generation with the 68,000 processors.
With much higher performance, additional commu-
nications interfaces and built-in Web and IT func-
tions, all Saia® PCD controllers are now at the cutting
edge of technology. All controls are provided in the
basic version with the Automation Server, one USB
and one Ethernet interface. As long as there is space
available, the Ethernet connection is a 2-port switch.
User programs are still compatible
For the user, a generational change is much more
hassle if the old and new systems are not compat-
ible and existing applications have to be rewritten.
Not so with the Saia® PCD controllers from Saia-Bur-
gess Controls, which accord with the values and cul-
ture of a real PLC company. When developing PCD
controllers, the biggest priority is a long life cycle in
order to minimize the effort and costs for users and
operators.
The necessary adjustments to the new hardware
platforms are made in the operating system. Thanks
to the interpreter technology, the interface for pro-
grammers is compatible with all controller fami-
lies for years to come. The interpreter language is
constantly being extended with new features,
while the existing functions continue to be sup-
ported. So existing application programs for the
first Saia® PCD-generation can be ported to the new
Saia® PCD controllers without additional expense.
The Saia® PG5 software is a programming tool for all
controller types and generations. Older programs
may be expanded and updated with the latest ver-
sion of PG5. Application programmes designed for
small Saia® PCD1s can also be used on the large
Saia® PCD3 CPU. The examples below prove that this
isn’t just marketing blurb:
AutomationServer,
keine Option immer dabei!
In 2011 we removed the old Saia® PCD-Generation
and replaced them with something fully compatible.
Old application programs can be transferred to the
new Saia® PCD controllers and expanded and proc-
essed with PG5.
In 2005, the first Saia® PCD3 controller was intro-
duced on the market. The upgrade of the flat series
with the Saia® PCD2.M5 CPU to the new technology
came in 2007. In 2011 the introduction of the new
Saia® PCD1.M2 CPU and the Saia® PCD3.Mxx6x-power
CPU completed the renovation of the first Saia® PCD
control generation. The new Saia® PCD controllers are
based on fast ColdFire processors and the latest web
and IT technology.
