Summary
Arcade Municipal Electric
Department had a C3-Ilex®
master station and Remote
Terminal Units (RTUs) for
monitoring and controlling
their distribution substations
and for demand load
management. They found
that the system could not be

automation vehicle. After a
careful analysis by their staff and their engineering
consultant ,they decided they needed an upgrade of the
complete system in order to take advantage of their
continuing SCADA investment.
After a thorough definition of their requirements,
development of a detailed specification and a
competitive bidding process and evaluation, a decision
was made to partner with QEI located in Springfield,
Upgrade Objectives
The original system from C3-Ilex consisted of a single
OS/2 server with traditional hardwired remote terminal
units. OS/2 was a series of computer operating
systems, initially created by Microsoft and IBM, then
Ilex RTUs were Replaced with the
ePAQ-9420 Substation Gateway.
later developed by IBM exclusively. It was introduced
as part of the IBM line of personal computers as a
successor to PC DOS. Unfortunately OS/2 was no
longer supported by IBM, and IBM development of
OS/2 was discontinued on December 31st, 2006. It
was supported by Ilex for a period, but it became clear
that it did not have the commercial success needed to
make it a viable long-term SCADA platform.
In order to avoid the previous problem with the OS/2
operating system, a well-established and continuing
server operating system was required and this was
addressed through QEI’s use of OpenVMS from
Hewlett Packard. The system’s man-machine
interface would take advantage of standard Windows®
PCs already present on the city’s enterprise network.
It was felt that the high reliability of the HP Itanium
servers proposed would eliminate the need for
redundant servers and this would be an additional cost
saving.
Reduce Cost Through Integrated SCADA
In addition to the
hardwired status, analog
and control points
supported by the existing
Ilex RTUs, the new
substation Gateway
would have to have
complete data
concentration and
management capabilities
for the existing
substation IEDs
(primarily Schweitzer®
relays)
Project
Implementation
The hardware platform for the central SCADA
server was the Hewlett-Packard Itanium® RX-2800
Server with the OpenVMS Operating System & NAS
Network Services. This operating system is used
worldwide in power, finance, medical, military and
other high availability applications. There has
never been a successful worm or virus attack on
any OpenVMS based system.

All editors were supplied by the vendor which will allow
expansion or modification of the SCADA system without
reliance on vendor personnel. All hardware and
software were supported by a warranty covering
update, replacement and essentially unlimited dial-in
assistance. These warranties are extensible on a year to-year basis.
Configuration of the new master station point database
for the substation IEDs was accomplished using the
TDMS-Plus editor. This point editor allows for creation
and editing of individual IED and hardwired points as
well as bulk editing of points through the ability to export
the system database to an Excel® Spreadsheet and do
editing through standard search and replace functions.
When the database elements have been changed in the
spreadsheet, it is re-imported into the TDMS Master
station database itself.

While all editors and training were provided to
village personnel for IED integration and display
development, the system database and all initial
displays were generated by the QEI database
generation group in Springfield New Jersey.
Database management
tools (also provided to
the village as part of the
QEI standard offering)
allowed easy
integration of the Ilex
database into the new
master station and
gateways.
As open protocols were
provided, (DNP3.0 and
MODBUS) the
integration of any
additional IEDs is
quickly accomplished
by the user with the
tools provided.
Additional protocols
(such as IEC-61850)
can be easily
incorporated into this
system when the need
arises.
