hand for reference during operation.

!WARNING It is extremely important that a Controller Link Support Board for PCI Bus and

all related devices be used for the specified purpose and under the specified
conditions, especially in applications that can directly or indirectly affect
human life. You must consult with your OMRON representative before apply­ing a Controller Link Support Board for PCI Bus to the above mentioned appli­cations.

3 Safety Precautions

!WARNING Never attempt to disassemble any Controller Link Support Board for PCI Bus

while power is being supplied. Doing so may result in serious electrical shock
or electrocution.

!WARNING Never touch any of the terminals while power is being supplied. Doing so may

result in serious electrical shock or electrocution.

!WARNING Provide safety measures in external circuits (i.e., not in the Programmable

Controller), including the following items, to ensure safety in the system if an
abnormality occurs due to malfunction of the Programmable Controller or
another external factor affecting the operation of the Programmable Control­ler. “Programmable Controller” indicates the CPU Unit and all other Units and
is abbreviated “PLC” in this manual. Not doing so may result in serious acci­dents.

xiv

• Emergency stop circuits, interlock circuits, limit circuits, and similar safety
measures must be provided in external control circuits.

Operating Environment Precautions 4

• The PLC will turn OFF all outputs when its self-diagnosis function detects
any error or when a severe failure alarm (FALS) instruction is executed.
Unexpected operation, however, may still occur for errors in the I/O con­trol section, errors in I/O memory, and other errors that cannot be
detected by the self-diagnosis function. As a countermeasure for all such
errors, external safety measures must be provided to ensure safety in the
system.

• The PLC outputs may remain ON or OFF due to deposition or burning of
the output relays or destruction of the output transistors. As a counter­measure for such problems, external safety measures must be provided
to ensure safety in the system.

• Provide measures in the computer system and programming to ensure
safety in the overall system even if communications errors or malfunc­tions occur in data link communications or remote I/O communications.

• When the 24-VDC output (service power supply to the PLC) is overloaded
or short-circuited, the voltage may drop and result in the outputs being
turned OFF. As a countermeasure for such problems, external safety
measures must be provided to ensure safety in the system.

!Caution Execute online edit only after confirming that no adverse effects will be

caused by extending the cycle time. Otherwise, the input signals may not be
readable.

!Caution Confirm safety at the destination node before transferring a program to

another node or changing contents of the I/O memory area. Doing either of
these without confirming safety may result in injury.

!Caution Tighten the connector screws for the backup power supply to the torque spec-

ified in this manual. The loose screws may result in burning or malfunction.

4 Operating Environment Precautions

1-1 Overview

1-1-1 What Is the Controller Link?

The Controller Link is an FA network that can send and receive large data
packets flexibly and easily among advanced OMRON Programmable Control­lers (CS-series, CJ-series, C200HX/HG/HE-series, CQM1H-series, CVM1,
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.

Overview Section 1-1

Note The following models must be used to create a wired network that contains

more than 32 nodes: 3G8F7-CLK23-E, 3G8F7-CLK21-EV1, CS1W-CLK23,
CS1W-CLK21-V1, CJ1W-CLK23, and CJ1W-CLK21-V1.

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 (includ-

ing 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, optical fiber cables, or optical ring optical fiber
cables. The optical ring optical fiber cables can be either H-PCF cables or GI
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 computer board for easy system assembly 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
network using a simple switch.

Features of Optical and Optical Ring Systems

Optical fiber cable (H-PCF cable or GI cable) has superior noise resistance,
so the system can provide highly reliable communications even in very noisy
conditions.

With H-PCF cable, the total communications distance can be up to 20 km
(1 km max. between nodes using adhesive polishing). With GI cable, the com­munications distance can be up to 30 km (2 km max. between nodes using

62.5/125 μm cable), which allows long-distance and 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 PCs

The following Controller Link Units are available for communications between
different PCs. Wired Units and Optical Units, however, cannot be used
together in the same Controller Link Network. (Optical and Optical Ring Units
can exist in one Controller Link Network using H-PCF cables, but with GI
cables, on an Optical Ring Unit is available.)

Flexible Internetwork Connections

The Controller Link Network can be connected to another network (Ethernet,
SYSMAC NET Link, SYSMAC LINK, or another Controller Link network)
through a CS-series or CV-series PC. By installing Ethernet, SYSMAC NET
Link, or SYSMAC LINK, or Controller Link Communications Units on the same
CS1-series PC or CV-series PC, a message service can be created with
nodes in the interconnected networks through that PC. Up to three network
levels are possible.

Node Bypass Function In an Optical or Optical Ring Controller Link Network, data communications

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 Net­work, another node automatically becomes the polling node with the help of
the Polling node backup function. This prevents an error at a single node from
influencing other nodes on the network, achieving a highly reliable system.

can be continued by bypassing the node, even when a node in the communi­cations line malfunctions or the PC or computer power supply is turned OFF.
This prevents the whole network system from being affected by a node mal­function or power interruption.

To use the bypass node function, backup power must be supplied to the Con­troller Link Unit/Support Board.

Transmission Path

Node Connection
Configuration Data
Reading

In Token Ring Mode in an Optical Ring System (H-PCF cable or GI cable),
data transmission will be unaffected even by a cable or connector break at
one location in the ring connection. With the optical cable wired in a ring
shape, a break at one point will simply cause the transmission to be routed on
the other path.

Even with transmission path duplication, the network will be broken if discon­nections occur in two or more places. In Token Ring Mode in an Optical Ring
System (H-PCF cable or GI cable), the location of a disconnection can be
detected and identified by means of the node status information given for all
nodes. This function can be used to prevent system crashes in advance, e.g.,
by performing maintenance when a disconnection occurs at one location.

In Token Ring Mode in an Optical Ring System (H-PCF cable or GI cable),
connection data can be read for all of the nodes in the network. The informa­tion that can be read includes the order in which the nodes are connected and
which of two optical connectors is connected to which node. Special support
software (Controller Link Support Software, Ver. 2.00 or later) is required to
read the node connection configuration data.

Using Repeater Units for T-Branches, Network Extensions, Network Expansions,
Converting Network Sections to Optical Fiber, and Device Modularization

T-Branches enable greater wiring freedom during layout, restructuring, and expansion of
networks.

Wire-to-Wire Repeater Units enable Controller Link T-Branches. T-Branches
provide the following advantages:

• Cabling can conform to the layout of equipment.

• It is possible to add nodes by adding or inserting Repeater Units at
branch points of an existing wired Controller Link system.

• If Repeater Units are installed at likely future branch points in the network
in advance, new nodes can be added by simply connecting them to these
Repeater Units.

The total length of wired networks can be extended.

At a baud rate of 2 Mbps, conventional wired networks can be up to 500 m
long. By using two Repeater Units, this can be extended to a maximum of

1.5 km.

The maximum number of nodes can be extended to 62 for wired networks.

By combining version-1 Controller Link Units/Support Boards and a Repeater
Unit, it is possible to construct networks containing up to 62 nodes.

Improved noise resistance through the use of optical cabling.

By installing two Wire-to-Optical Repeater Units, optical cabling can be used
for sections of the network that are the source of noise.

Devices can be modularized.

• Devices can be modularized according to Repeater Units, making wiring
easier when adding, removing, or modifying devices.

• When starting up devices, components can be added to the network and
debugged as they are completed.

Refer to the Controller Link Unit Operation Manual (W309) for information on
using Repeater Units.

Overview Section 1-1

Features and Functions of Version-1 and CLK23 Models

The following features and functions apply to the CS1W-CLK23, CS1W­CLK21-V1, CJ1W-CLK23, and CJ1W-CLK21-V1 Controller Link Units and the
3G8F7-CLK23-E and 3G8F7-CLK21-EV1 Controller Link Support Board only.

Up to 62 nodes can be connected.

Overview

When a CS1W-RPT01 Repeater Unit is used, the maximum number of nodes
that can be used in the network increases to 62. (The previous limit was 32.)

Method

Use Repeater Units and select Max Node Number set 62 in the FinsGateway
drive settings to enable a maximum of 62 nodes.

Restrictions

• The maximum of 62 nodes cannot be achieved if pre-version-1 models
are used together in the same network with version-1 models or with
CLK23 models (i.e., the CS1W-CLK23, CJ1W-CLK23, or 3G8F7-CLK23­E).

• Using the maximum 62 nodes can be enabled using FinsGateway 2003.
This setting is not possible with FinsGateway version 3.@@.

Automatic data link creation is possible with 1:N allocations.

Overview

It is possible to perform unequal 1:N allocations of data between nodes with
automatic data link creation. This makes it easy to perform data links that for­merly required the user to manually edit data link parameters.

The following four automatic data link creation patterns can be used:

• Equality layout (the previous pattern)

• 1:N allocation, common type

• 1:N allocation, 1 to 1 type

• 1:N allocation, chain type

This setting can be made in CS-series or CJ-series Controller Link Units.

Method

Allocation addresses and sizes are all specified using the Automatic Data Link
Creation Parameters (D30000 × Unit No. + 12 to 20) in the DM Parameter
Area. These values can be set using the CX-Net in the CX-Programmer ver­sion 3.2 or later.

Objective

This function is effective in applications that collect data from slave PCs into a
master PC.

Restrictions

• A Controller Link Support Board cannot be set as the startup node.

• These settings can be made using FinsGateway 2003. They are not pos­sible with FinsGateway version 3.@@.

Automatic data link creation with 1:N allocations cannot be performed if pre­version-1 models are used together in the same network with version-1 mod­els or with CLK23 models (i.e., the CS1W-CLK23, CJ1W-CLK23, or 3G8F7­CLK23-E).

Overview Section 1-1

Change manually created data link tables during data link operation.

Overview

It is possible to modify a manually created data link table while data links are
running.

Note This is possible only with manually created data link tables. Any attempt to

change automatically created data link tables when data links are running will
fail and an error message saying that the tables cannot be edited during data
link operation will be displayed.

Method

This function can be set using the CX-Net in CX-Programmer version 3.2 or
later.

Objectives

• In systems that operate non-stop and cannot be turned OFF, this function
makes it possible to change the data link table to accommodate the addi­tion of new nodes and to transfer data link tables without having to stop
manually set data link communications.

• If this function is combined with the use of Repeater Units to add network
nodes, it becomes possible to construct systems of greater flexibility.

Operation

When a node is being modified online, this function temporarily stops refresh­ing of data link data until modifications have been completed.

Nodes will participate in data links after changes to the data link table have
been completed.

Note Refer to the Controller Link Unit Operation Manual (W309) for information on

changing user-set data link tables while the data links are active.
