The new 1⁄32 DIN CN9500,
1
⁄16 DIN CN9300 Single Display
and1⁄16 DIN CN9400 Dual Display
controllers follow the OMEGA
tradition of innovative design.
Building on the success of the
CN132 and CN9000A series, the
new models include several new
features, the most important being
the option of a low cost serial
communicating system with easy to
use Windows-based software.

⁄32 DIN
The CN9-SW series software
bridges the gap between the “stand
alone” system and full SCADA of
Fieldbus control networks by
providing a facility for remote
supervision of up to 32 instruments
using MODBUS protocol. It requires
only a modest investment and can
be operated by anyone with a
medium specification PC or laptop
that can be run with Windows 95
or Windows NT.

The CN9-SW software is designed
to interface with the CN9300,
CN9400 and CN9500 series
controllers with optional
communication hardware.
The CN9-SW takes up
approximately 1Mb. The size is
dependent on the number of
controllers and the frequency that
they are being logged. A very
approximate figure is per reading:
12 bytes date/time plus 4 bytes for
each instrument being logged.
Designed for use on laptops or
PC’s, this new development
provides the user with:
Model CN9300
• Time saving benefit and convenience
of remotely configuring and
adjusting units.
• Saving and retrieving settings to
and from files.
• Cloning settings to other
instruments.
• Highly flexible logging and
“real time” charting capability for
providing hard copy QA records
for ISO-9000 and other
management purposes.
Screen displaying alarm condition on instrument 1.
Software alarms provide a screen indication if the measured value falls
below the low alarm and/or rises above the high alarm settings.

The CN9-SW software
is a powerful process
development tool for the
OEM customer or process
engineer. With compatible
modems and PC computers,
remote site supervisory control
and data acquisition can take place
to facilitate periodic or continuous
monitoring and troubleshooting.
Data is stored to file in a tamper
resistant format to ensure the
integrity of reports for quality
monitoring requirements. Build your
own multi-loop system with the
CN9300/CN9400/CN9500 series
controllers and CN9-SW software.
Allows both local and remote
adjustment. The CN9-SW software
can be used as a production tool for
the OEM. Downloading menu
settings to controllers during
production saves time and
eliminates errors.

cloning function for multiple
controllers. When a satisfactory
instrument configuration has been
achieved, these settings can be
cloned to other instruments
on the network or saved to a file
for later use.

Sample of graph displaying "real time
charting." Software is capable of
logging readings from up to 128
instruments which it stores in data
files. The data can be exported into
text files in C.S.V. (Comma Separated
Variable) format. In addition, up to 12
controllers can be displayed on a
single chart, or individual charts can
be set up for each instrument.
Virtual full color chart recorder can
log process variables such as: °C, °F,
Bar, PSI, pH, or rH. User definable
engineering unit "Set" can be
selected on the controller to log
other process variables.
