Industrial Networking and Communications
Controller Link: Peer-to-Peer Control Network
Why Use Controller Link?
Omron’s Controller Link complements Ethernet by
providing access to mission critical information while not
disturbing the timing or execution of the main control
system. It was designed specifically to handle large data
transfers in applications with these requirements.
J You’ll Achieve These Goals
•

•
These requirements can be met perfectly using Omron’s
Controller Link network, a network designed specifically
for critical timing and large data transfers. Controller Link
provides these capabilities by combining an automatic data
link service with a messaging service that enables sending
and receiving data when required by process conditions.
The result is highly flexible data sharing that provides de-
terministic system response with highly effective use of
data areas within the PLCs. (Refer to the Data Links
illustration on this page.)

B-82
Large amounts of information can be transferred from
controller to controller automatically, and/or by using
specific commands.
You will utilize a supervisory system that will be
constantly updated as it coordinates the output from
one manufacturing cell to the next.
Timing will be deterministic so that performance is
repeatable.
Controller Link supports up to 62 nodes (using Repeat-
er Units), and each node can transmit up to 1000 words
(16 bits = 1 word) of data.
Determinism is accomplished through the use of a
token passing scheme, and CRC error checking
ensures that the data gets through.
Controller Link’s two media options are Shielded
Twisted Pair (STP) and optical fiber.
Like all Omron networking products, Controller Link
supports transparent network routing and gateway
functions while providing deterministic high-speed
data transmission.

J Controller Link Provides Two Powerful
The first is a Data Link service — large, user defined
amounts of shared memory is instantaneously updated in
all the other connected controllers.
Data Links
The second is a Messaging service that can transmit data
between specific nodes on specified events using simple
ladder instructions.
Message Communications
