Product Warranty (2 years)
Advantech warrants the original purchaser that each of its products will be free from
defects in materials and workmanship for two years from the date of purchase.
This warranty does not apply to any products that have been repaired or altered by
persons other than repair personnel authorized by Advantech, or products that have
been subject to misuse, abuse, accident, or improper installation. Advantech
assumes no liability under the terms of this warranty as a consequence of such
events.
Because of Advantech’s high quality-control standards and rigorous testing, most
customers never need to use our repair service. If an Advantech product is defective,
it will be repaired or replaced free of charge during the warranty period. For out-of-
warranty repairs, customers will be billed according to the cost of replacement mate-
rials, service time, and freight. Please consult your dealer for more details.
If you believe your product to be defective, follow the steps outlined below.

Safety Precautions - Static Electricity
Follow these simple precautions to protect yourself from harm and the products from
damage.
To avoid electrical shock, always disconnect the power from the PC chassis
before manual handling. Do not touch any components on the CPU card or
other cards while the PC is powered on.
Disconnect the power before making any configuration changes. A sudden rush
of electricity after connecting a jumper or installing a card may damage sensitive
electronic components.

1.1 Introduction
Upgrades of smart grid technologies are in demand in this new era motivated by the
requirement for rugged computing platforms with faster processors and increased
reliable storage capacity in modern substation automation systems. To fulfill the per-
formance requirements of modern distributed software applications which require fast
processing, Advantech offers ECU-579 which is targeted at advanced server-level
data concentrators and protocol converters in scenarios like substation automation,
energy management, secondary communication and control, etc.
In years past, substations were managed under the well-established SCADA OT sys-
tem. Now, in this next phase of virtualization, more centralized computing is a better
fit for the requirement of higher energy efficiency. There is also a demand for immedi-
ate and flexible optimization based on the cloud-as-a-service business model.
ECU-579 is certified with IEC 61850-3, the standard for electrical substation automa-
tion design, which ensures high reliability and stability. The standard is suitable for
any global power & energy automation market and defines communication between
all intelligent electronic devices (IED) and other related equipment from the process
level (data acquisition, sensors, and actuators), providing high performance and reli-
able functionality to meet the needs of the most critical computing applications. It also
supports remote monitoring and diagnosis and remote device connectivity to
enhance maintenance efficiency.
Isolation & High-Speed Communication Interface
A comprehensive communication interface is used for smart substation commu-
nication servers and IED analyzers to easily implement data gateway & protocol
conversion. There is support for a variety of protocols (IEC-60870-104, DNP3.0,
etc.).
Network interfaces are required to respond to real-time data and collect high-
density network packets and accurately facilitate data analysis.
Versatile communication interface: the IED analyzer easily fulfills the data gate-
way & protocol conversion requirement.
Easy to Diagnose and Maintain in an Efficient Manner
Remote diagnosis can be done and the system can be managed to provide high
system maintenance efficiency.
The rear I/O connections and LEDs on the front panel are for various ports and
modes, simplifying the monitoring of operation status.
Fast and Easy Customization
The structured and functional internal design of the module allows for easy cus-
tomization and fast assembly to suit different kinds of applications for the CTOS
manufacturing process.
Customer-focused service provides fast response for customization requests
based on this product's main hardware structure.

Warning! Always disconnect the power cord from your chassis whenever you are
working on it. Do not connect it while the power is on. A sudden rush of
power can damage sensitive electronic components. Only experienced
electronics personnel should open the chassis.
Caution! Always ground yourself to remove any static electric charge before
touching the ECU-579 series. Modern electronic devices are very sensi-
tive to static electric charges. Use a grounding wrist strap at all times.
Place all electronic components on a static-dissipative surface or in a
static-shielded bag.
Note! If DC voltage is supplied by an external circuit, please put a protection
device in the power supply input port.
