1-1 Overview
1-1-1 What Is the Controller Link?
The Controller Link is an F A network that can send and receive large data pack -
ets flexibly and easily among advanced OMRON Programmable Controllers
(CS1-series, C200HX/HG/HE-series, and CV-series PCs) and IBM PC/AT or
compatible computers.
The
Controller Link supports data links that enable data sharing and a message
service that enables sending and receiving data when required. Data link areas
can be freely set to create a flexible data link system and effectively use data
areas.
The network is connected using either shielded twisted-pair cable or optical fiber
cable, and high-volume data transmissions at high speed enable construction of
a wide range of networks, from low-level systems to high.

1-1-2 Features The Controller Link FA Network has the following features to meet the various
requirements of FA sites.
Data Links Flexible and efficient data links can be created for large capacities of data as
listed below.
Item Specifications
Number of send words
per node 1,000 words max.
Number of send and
receive words per node Controller Link Support Board: 32,000 words max.
Controller Link Unit for CS1 Series:
12,000 words max.
Controller Link Unit For C200HX/HG/HE or CV Series:
8,000 words max.
Data links can be automatic set, or they can be set by the user to freely change
the sizes of the data areas used. A data link can also receive only part of the data
sent from another node. This function enables users to receive only the required
data, thereby increasing data link efficiency.
Message Service The
message service can send and receive up to 2,012 bytes of data (including
the FINS header), allowing high volumes of data to be sent and received without
having to split it up.
Twisted-pair Cable or Optical Fiber Cable Connection
The Controller Link Units can be connected to the network using either shielded
twisted-pair cables or optical fiber cables. Select the system that suits the
application.
Features of Twisted-pair Cable
Twisted-pair cable is easy to connect and maintain. The cable can be processed
much more easily than coaxial or optical cable, thereby reducing the cost of tools
and assembly time.
Connections are made to a terminal block on the Controller Link Unit and to a
special connector on the Controller Link Support Board for easy system assem -
bly and modification.
The network is equipped with the required terminating resistance built into the
Units allowing the terminating resistance to be easily set at both ends of the net -
work using a simple switch.

Features of Optical Fiber Cable
Optical Fiber Cable has superior noise resistance, so this system can provide
highly reliable communications even in very noisy conditions.
The communications distance can be up to 20 km in total (1 km max. between
nodes), which allows long-distance or large-scale networks.
Once the Optical Fiber Cable has been fitted with special connectors, the cables
can be easily connected or disconnected.
Communications between Different Models
The following Controller Link Units are available for communications between
different models. It must be noted, however, that the wired system and optical
system cannot exist in one Controller Link Network.
Wired System
•Controller Link Unit for CS1-series Programmable Controllers
•Controller Link Units for C200HX/HG/HE Programmable Controllers
•Controller Link Units for CV-series Programmable Controllers
•Controller Link Support Board for IBM PC/AT or compatible computers
Optical System
•Controller Link Unit for CS1-series Programmable Controllers
•Controller Link Support Board for IBM PC/AT or compatible computers
Flexible Inter-network Connections
The Controller Link Network can be connected to another network (Ethernet,
SYSMAC NET Link, SYSMAC LINK, or another Controller Link network)
through a CS1-series or CV-series PC. By installing Ethernet, SYSMAC NET
Link,
or SYSMAC LINK Communications Units on the same CS1-series PC or
CV-series PC, a message service can be created with nodes in the intercon-
nected networks through that PC. Up to three network levels are possible.
Improved Error Handling An error log enables quick handling of errors by recording the time the error
occurred
and error details. The current Controller Link Unit and Support Board
status are also available, as are the data link and network status.
When an error occurs in the polling node that controls the Controller Link Net-
work, another node automatically becomes the polling node. This prevents an
error at a single node from influencing other nodes on the network, achieving a
highly reliable system.
With the Optical Controller Link Network, data communications can be contin-
ued even when a node or its power supply fails. The disabled node (PC or IBM
PC/A T or compatible computer) is bypassed by the network. This bypass func -
tion prevents the network from crashing because of a single node failure or
power interruption. A backup power supply must be provided to each node (Con -
troller
Link Unit or Support Board) to take advantage of the node bypass func -
tion.

1-1-3 What Is a Controller Link Support Board?
A Controller Link Support Board is used to provide a direct connection to an IBM
PC/AT or compatible computer on a Controller Link Network. A Controller Link
Support Board supports data links, the message service, and RAS functions in
the same way as a Controller Link Unit.
The Controller Link Support Board is supported by DOS. The Support Board is
mounted in an expansion slot of an IBM PC/AT or compatible. The following
Support Boards are available.

1-1-6 Outline of Features
Data link data for each node is reflected in the shared memory area on the
Board. When a data link cache is used, the data is edited according to the data
link table and is stored in the data link cache area in memory . A data link cache
area is not created unless a data link cache area is specified.
Users can access either the data link buf fer in the shared memory or the data link
cache area. The access method is selected by setting the Controller Link BIOS.
Only one method can be used at a time.
The following figure illustrates reading and writing the data link cache area.

Note Check the available memory. The data link cache area occupies 64 Kbytes of
conventional memory or XMS memory.
Data in area 1 and area 2 for each node is allocated consecutively in both the
data
link cache area and the shared memory data link buf fer . When using data
link cache areas, areas for each node are allocated in the order of node
addresses set in the data link table.
When using data link cache areas, data for two or more consecutive nodes can
be read or written. When using the data link buf fer in shared memory (i.e., when
not using data link cache areas), data in two or more nodes cannot be read or
written concurrently.
The data link start word and data link status words are fixed.

Note 1. Users can set whether data link cache areas are used when the Controller
Link Support Software is installed (see page 44). The setting can be
changed
by modifying the CONFIG.SYS file after installation (see page 50).
2. Use data link cache areas to create an application to read the data in the
data link areas of two or more nodes at the same time (i.e., using the same
function call or driver call). T o do this, 64 Kbytes must be available in conven -
tional memory or XMS memory.
