Seamless Message Protocol
(SLMP)
Rapid path to support for CC-Link IE Field
No hardware development
Simplified conformance testing
The fast way to a CC-Link IE
Field product
Overview
CC-Link IE is the open industrial
Ethernet version of the globally
successful open fieldbus, CC-Link. The
two networks have a leading share in
the Asia Pacific market, where it has
been estimated that approximately
half of the world’s spending on
automation takes place. Furthermore,
independent research has shown
that CC-Link IE is experiencing
the fastest growth of any type of
industrial Ethernet. Finally, CC-Link
IE is unique in being the only open
industrial Ethernet type that operates
at gigabit speeds, allowing it to offer
productivity benefits around ten times
greater than the competition.
CC-Link IE is divided into two main
types. CC-Link IE Control is a high
speed, high capacity optical fibre
“backbone” that is intended for
the real-time sharing of information
across production lines, factories and
beyond. CC-Link IE Field provides
the link between controllers and
field devices to bring the benefits of
industrial Ethernet to machines and
systems. However, no matter which
one (or both) is the best fit for your
application, the key benefit is that
both operate at gigabit Ethernet
speed, meaning both provide industry
leading productivity benefits.
Product development
When it comes to offering a CC-Link
IE product, companies can take the
usual route and develop hardware
and software to produce the required
product. However, since CC-Link IE
uses the standard Ethernet physical
layer, the CC-Link Partner Association
(CLPA) also offers a faster route to
offering a product. The Seamless
Message Protocol (SLMP) is a way to
offer a product that is compatible with
the CC-Link IE Field network without
having to undertake any hardware
development.
FA network is fully covered by CC-Link IE.

How does it work?
Since SLMP is only a protocol and
not a set of hardware specifications,
implementation only relies on
supporting this protocol in software
on your existing Ethernet enabled
device. Hence a product can be
more quickly developedServer
at lower
(Controller)
cost than is involved with
hardware
development. Once

the product simplyStation
connects to an

and can exchange information

with other CC-Link IE Field
devices. A further benefit is that the
conformance testing requirements
are simplified, as only the software
functions need to be tested.

Help from
the CLPA
CC-Link IE is seeing rapid growth
in the Asia-Pacific market. Any
company looking to increase their
business globally needs to include
this vital technology in their portfolio
or risk missing a growth opportunity.
SLMP provides a rapid, simplified
way to take advantage of this
opportunity and extend the market
reach of your existing industrial
Ethernet products. Whether it is a
vision system, PLC, inverter, servo or
something else, these products are
all likely to be capable of supporting
SLMP and seizing this opportunity.

Client
Asia, the CLPA offers the “Gateway
to Asia” programme (G2A). This
takes advantage of our market
leading position in Asia and works
with companies to promote sales
of their SLMP enabled devices in
this critical global market. The only
conditions are to pass the SLMP
conformance test and become a
Regular member of the CLPA (a fee
of EUR 1,000.00 per year). After
this, the CLPA can work with you in
key Asian markets to help develop
your business in this region.
