Advanced Control Systems Passes ISO New England DNP3 Conformance Tests

ATLANTA, March 24 /PRNewswire/ -- Advanced Control Systems, Inc. (ACS), a
leading provider of smart grid automation and system solutions to electric
utilities worldwide, announced that its Connex 30 substation manager has
successfully passed the ISO New England DNP3 conformance testing, which
includes DNP3 2009 Level 4 functionality. The Connex 30 meets all of the
Remote Terminal Unit (RTU) specification requirements as a replacement for the
obsolete Remote Intelligent Gateways (RIG) currently in use by ISO-NE market
participants.

The specifications define the requirements for communication between the ISO
New England Communications Front End (CFE) System servers and the RTUs owned
by market participants. The existing proprietary RIG infrastructure used by
ISO-NE is being replaced with a DNP3-based CFE and RTU system. ISO-NE tested
the ACS Connex 30 using the actual configuration with market and reliability
data from a current market participant. The tests fully demonstrate the Connex
30's ability to provide secure and reliable data transfer between the systems.

ACS' Connex 30 solution includes all of the core RIG functionality currently
in use, so market participants can be assured of a smooth and seamless
transition from their legacy devices. More importantly, the Connex 30 provides
users with several advantages over competing RIG replacement solutions:

- This critical application demands a field-proven solution. The
Connex 30 has an impeccable reliability record, with over 400
installed units to date.

- The Connex 30 is a network-enabled, high-performance data management
platform that can be deployed as an intelligent electronic device
(IED) gateway, protocol translator and conventional RTU.

- The integrated Human-Machine Interface (HMI) module provides users
with graphical monitoring capabilities that go well beyond a simple
anunciator panel.

- The Connex 30 offers fully-compliant DNP3 2009 Level 4 functionality
(available in selected configurations).

- With 34 years of experience as an RTU manufacturer and innovator,
ACS can provide a turn-key solution for ISO-NE market participants,
providing installation, configuration, point-to-point testing and
support services - all from a single vendor.

The modular and flexible Connex 30 platform is also an extremely
cost-effective retrofit option for legacy RTUs. This means that ISO-NE market
participants can utilize the same Connex 30 RIG replacement platform as an
upgrade kit for many aging RTU models.
