Communication in automation – no more«it doesn’t work»!
Lean automation
In many communications from Saia-Burgess, the
automation pyramid is described as a key ele-
ment. It conveys a graphical symbol of our
own image as a provider of great freedom
in communication technologies to users of
Saia® PCD automation technology.
Both now and in the future, users
can integrate all common fieldbus
communication systems into the
automation
of
infrastructure
facilities. Thanks to web tech-
nology and IT the boundaries are open and trans-
parent. The modular design of Saia® PCD automa-
tion technology also allows for the upgrading of
bus system generations in the future.
The ability to integrate and future-proof should
be achieved selectively. According to the
«
Peace of Mind» principle, to which Saia-
Burgess subscribes, the integration of
field communications can take place
easily, safely, and efficiently.
For this reason, external cou-
plers are omitted as much as
possible. In practice, these are often a
source of error even during installation
and commissioning. They also cause errors
throughout the life cycle.
Therefore Saia-Burgess developed commu-
nication modules as an integral part of the
Saia® PCD automation stations. Always regarding
the overall solution, the necessary development
projects are started, provided that the revenue gen-
erated is reasonable for the small quantity of items
produced. The two communication modules for the
M-Bus and DALI-coupling were finished in 2011.
The M-Bus master modules are designed for Saia-
NT-based PCD controllers (i.e. PCD1.M2, PCD2.M5,
and PCD3 ) in four versions having 20, 60, 120 and
240
slaves. Each module is equipped with two sepa-
rate interfaces. The maximum number of connect-
able M-Bus counters can be split freely between
the modules. This allows for shorter cable lengths
and higher baud rates, which in turn allows for both
faster data exchange, as well as safer and more
efficient operation. All Saia®M-Bus master modules
have an internal power supply for the M-Bus.

Communication without limits, in line with all
current standards.
Use of all communication standards in all device series forever, flexibly, and securely.
This is the basis for lean automation. In this context, Saia-Burgess has developed new
interface modules and improved their integration into the engineering environment.

The M-Bus master modules available as PCD2.F2700
to F2730 for the Saia® and Saia® PCD1.M2 and
PCD2.M5 series. Plug-inmodules Saia® PCD3.F270 to
F273 support Saia® PCD3 controllers and the Smar-
tRIO Saia® PCD3.T666. They can be used on I/O slots

to 3 of PCD automation stations, where the theo-
retical maximum number of M-Bus meters per PCD
is rarely reached in practice. The range of functions
and the available programmemory and PLC resourc-
es means projects of any size may be undertaken.
For engineering, prefabricated FBoxes for the mas-
ter modules (function boxes) are available for the
FUPLA environment of the Saia® PG5. This allows
the application software to be implemented very
easily and quickly. A communication driver module
(
M-Bus master) with a plain text label will connect
to the following device-specific M-Bus function
modules.
European standard (EN13757) for consumption data
acquisition. The M-Bus meters can monitor and con-
trol the consumption of water, gas, electricity and
heat. The data is transmitted serially via a polarized
two-wire line.
