Conformance to EC Directives6
6Conformance to EC Directives
The Controller L ink Units conform t o EMC and Low Voltage Directives as follows:
EMC Directives
OMRON devices that comply with EC Directives also conform to the r elated
EMC standards so tha t they can be more eas il y built i nto ot her d evices or th e
overall machine. The actual products have been checked for conformity to
EMC standards (see the following note). Whether the products conform to the
standards in the s ystem used by the custo mer, however, must be che cked by
the customer.
EMC-related perfor ma nce o f th e O M RON devices that c omp ly wi th EC Di re ctives will vary depending on the configuration, wi ring, an d other conditio ns of
the equipment or control panel on which the OMRON devices are installed .
The customer must, therefore, perform the fi nal c heck to confir m th at devices
and the overall machine conform to EMC standards.
Always ensure that devices operating at voltages of 50 to 1,000 VAC and 75
to 1,500 VDC meet the required safety standards for the PLC (EN61131-2).
The Controller Link Units that comply with EC Directives (CVM1-CLK21,
C200HW-CLK21, CS1W-CLK21(-V1), CJ1W-CLK21(-V1), and CQM1HCLK21) must be installed as follows:
1. The Controller Link Units are desig ned for ins tallation inside control panels. All Controller Link Units must be installed within control panels.
2. Use reinforced insu lation or double insulati on for the DC power supplies
used for the communications power supply and I/O power supplies.
3. The Controller Link Units that compl y with EC Direc tives also c onform to
the Common Emission Standard (EN61000-6-4). Radiated emission characteristics (10-m r eg ula tio ns ) may v ar y depending on the con f ig urati on o f
the control panel used, o ther d evices conne cted to the c ontrol panel , wiring, and other cond iti ons . You must therefore confirm t hat the overall machine or equipment complies with EC Directives.

SECTION 1
Features and System Configuration
This section provides basic information on Controller Link Networks, and will give the reader an overview of what
Controller Link Networks can do and how best to use them.
The Controller Link is a n FA network that can se nd and receive large data
packets flexibly and easily among the OMRON C 200HX/H G/HE Programmable Controllers (PLCs), CS-series PLCs, CJ-ser ies PLCs, CVM1 PLCs, CVseries PLCs, CQM1H-series PLCs, and IBM PC/AT or compatible computers.
The Controller Link suppo rts data links that enable data shar ing 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.
High-volume data transmissions are possible at high speed and so a wide
range of networks, from low-level systems to high, can be easily created.
There are two types of networks: networ ks connected with shielded twist edpair cable and networks con nected with optical fiber c able. Using a Repeater
Unit in networks co nnected with t wisted-pair cable makes it possible to use a
variety of different wiring configurations, such as T-branch wiring, long-distance wiring, and partial conversion to optical fiber. (Refer to the CS1W-
CLK12, CVM1-CLK12 Optical Ring Controller Link Units Operation Manual
(W370) for detail on optical fiber connections.)

Data Links
Data links allow the constant sharing of data in predetermined data areas
between nodes, between PLCs, or between a PLC and an IBM PC/AT or compatible computer on the network. Dat a lin ks do not requ ir e the use of communications programs on the PLC (CPU Unit) or IBM PC/AT or compatible
computer. Data written in the send area of the local node will be automatically
sent to the receive area of other nodes.
The I/O area (CIO area), link area (LR area), DM Area area (DM area), an d
extended DM Area area (EM area) c an be freely set in the send or rece ive
area. (The area used for sending or receiving data using the data link function
is called “data link area.”)
The data link area can be set automatically or manually.

Automatic SettingUsed for simple data link processing. Data link can be performed by simply
setting parameters in the DM area of the PLC.
Send data size per n ode is the sa me for all nodes. All no des par ticipating i n
the data link share the same data.
Manual SettingUsed for flexible data link processing depending on each system.
Using the Controll er L ink Su pport Software, indivi dual data link tables can be
set for each node and the data link area can be freely allocated for each node.
Send data size per node can be fre ely set. It is als o possible to set nod es for
only send or rece ive data. With the Controller Link Unit, the data link can be
set to receive only a part of the data link area of other nodes.
Message Service
This function controls data transmission with particular nodes, reading or writing of status data, c hangi ng of op eration mod es, etc., by executing communications instruc tions on a program. The communications instr uctions include
SEND/RECV instructions for data transmission and CMND instructions for
issuing various commands.

SEND/RECVThe SEND or RECV instruction sends or receives data in an area of a particu-
lar node.
The SEND instruction sends data from an area of the local node and writes to
an area in the designated node.
The RECV instructio n requests the designated node to send ar ea data and
writes the data to the local node.
CMNDThe CMND instruction issues a command to read or write data of other nodes,
control, or read erro r logs. With t he Control ler LInk Unit, O MRON’s command
protocol called “FINS commands” is used.
Note Since the C200HX/HG/HE PLCs do not s upport the CMND instr ucti ons, arbi-
trary commands cannot be issued.
RAS
RAS performs real-time monitoring of the network status. If an er ro r oc cu rs i n
the network, RAS records and displays the time and contents of the error.
Status AreaData Link Status Area
When the data link function is used, the data link status is reflected in the data

OverviewSection 1-1
1-1-2Features
The Controller Lin k Network has the following features to meet the vari ous
requirements of FA sites.
Data Links
Flexible and efficient data link s can be cr eated for large c apacitie s of data as
listed below.
ItemSpecifications
Number of send words

Number of send and
receive words per node
Data links can be auto matically set, or th ey can be set by the user to free ly
change the sizes of th e data areas u sed. A data link can also be created so
that one node receives only part of the data sent from another node. This
function enables users to receive only the required data, thereby increasing
data link efficiency.
Data link tables for which the number of send and receive words exceeds
12,000 words can be set using CX-Net in CX-Programmer Ver. 5.0 or higher.
1,000 max.
C200HX/HE/HG, CVM1, CV-series, and CQM1H-series PLCs: 8,000 max.
CS/CJ-series PLCs:
Pre-Ver. 1.2: 12,000 words max.
Unit Ver. 1.2 or later: 20,000 words max.
IBM PC/AT or compatible: 32,000 max. (PCI or ISA Board)
Message Service
The message ser v ic e c an send and r ec ei ve up to 2,012 bytes of data ( incl uding the FINS head er), allowing hi gh volumes of data t o be sent an d 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 your application.
Features of Twisted-pair Cable
Twisted-pair cable is easy to connect and maintain. The cable can be processed much more easi ly than coaxial or optica l cable, thereby reducing the
cost of tools and assembly time.
Connections are made to a ter mi nal block on the Controller Lin k Unit and to a
special connector on the Controller Link Support Board for easy system
assembly and modification.
The network is equipped with the required terminating resistance built into the
Units allowing the ter minating res istance to be easily set at bo th ends of the
network using a simple switch.
Features of Optical Fiber Cable
Optical Fiber Cable has superior noise resi sta nc e, so this sys tem c an pr ovid e
highly reliable communications even in very noisy conditions.
The communications d istance can b e up to 20 km total (1 km max. be tween
nodes) if H-PCF cable is used and up to 30 km total (2 km max. between
nodes) if GI cable is used, 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.

OverviewSection 1-1
Compatible with Different Node Configurations
The following Controller Link Units are available for communications between
different models. It must be noted, however, that the wired system and o ptic al
system cannot exist in one Controller Link Network.
Wired System
• Controller Link Unit for CS/CJ-series Programmable Controllers
• Controller Link Unit for C200HX/HG/HE Programmable Controllers
• Controller Link Unit for CVM1 and CV-series Programmable Controllers
• Controller Link Unit for CQM1H-series Programmable Controllers
• Controller Link Su pport Board for IBM PC/ATs or compatibles (ISA or
PCI bus)
Flexible Inter-network Connections
The Controller Lin k Network can connec t to other networks (Ethernet, SY SMAC NET, SYSMAC LINK, and another Controller Link networ k) via CVM1,
CV -series, CS-series, or CJ-series PLCs. By installing a Communications Unit
for the Ethernet, S Y SMAC NET or S YSMAC LINK on t he same CS/CJ-ser i es
or CV -series PLC as a Controller Link Unit, a message service can be created
with nodes in interconne cted networks through the CVM 1 or CV-ser ies PLC.
Up to eight network levels are possible.
Note CS/CJ-series PLC c annot be connected directly to SY SMAC NET networks
and CJ-series PLC cannot be connected directly to SYSMAC LINK networks
The programming and monitor ing of other PL Cs on the network c an be con-
ducted from Programming Devices connec ted to the PLC’s CPU Unit. Internetwork connectio ns are possible in thi s case also an d can cover up to eight
network levels.
Use a CS/CJ-series CP U Unit with unit version 2.0 or later and CX -Programmer Ver. 4.0 or hi gher to enable inter networ k connec tions for up to e ight networks.
Improved Error Handling
An error log enables qu ick handling of errors by reco rding the time th e 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. This prevents an
error at a single n ode from influe ncing other nodes on t he n etwor k, achieving
a highly reliable system.
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 Repeat er Units enable Controller Link T-Branches. T-Branc hes
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.
9
OverviewSection 1-1
• If Repeater Units are install ed at li ke ly futur e bran ch 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 R epeater Units, this can be extended to a maximum of
1.5 km.
The maximum number of nodes can be extended to 62 fo r wired networks.
By combining version-1 Co ntrol ler Lin k Uni ts/Support B oar ds a nd 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 Wir e-to-Optical Re peater Units, optica l cabling can be used
for sections of the network that are the source of noise.
Devices can be modularized.
• Devices can b e modularized ac cording to Repe ater Units, making w iring
easier when adding, removing, or modifying devices.
• When starting up devi ces, compon ents can be added to the network an d
debugged as they are completed.
Features and Functions of Version-1 Models
The following features and functions apply to the CS1W-CLK21-V1 and
CJ1W-CLK21-V1 Controller Link Units and th e 3G8F7-CLK21-V1 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 tu rn ON bit 11 (Wired Network 62 Nod e Enable Bit)
in the DM Parameter Area software switch D30000 + 100
nodes to enable a maximum of 62 nodes.
Restrictions
The maximum 62 nodes cannot be ach ieved if version-1 models a nd pr e-version-1 models are used together in the same network.
Automatic data link creation is possible with 1:N allocations.
Overview
It is possible to perform unequal 1:N all ocations of data between nodes wit h
automatic data li nk c r eati on . Thi s ma kes it e a sy to per for m d ata l inks th at 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

Restrictions
Automatic data link creation with 1:N allocat ions cannot be performed if version-1 models and pre-version- 1 models are used together in the same network.
Change manually created data link tables during data link operation.
Overview
It is possible to modify a manuall y created d ata link table whil e data links are
running.
Note This is possible only wit h manually created data link tables. Any attem pt to
change automatical ly cr ea ted data lin k ta bles when data li nk s are running will

Method
This function can be s et using the CX-Ne t in CX-Programmer version 3.2 or
higher.
Objectives
• In systems that ope rate non -s to p and cann ot be tu rn ed O FF, this function
makes it possible to change the da ta link ta ble to acc om mo date the add ition of new nodes and to transfer data link tables w ithout having to stop
manually set data link communications.
• If this function is co mbined with the use of Repeater Un its to a dd n etwo rk
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 par ticipate in data links after changes to the data link table have
been completed.

Note Normally, the communications cable must be disconnected from a Wired Con-
troller Link Unit to replac e it. Doing this, however, will interrupt c ommunications on the network, r equiring that all nod e be turned OFF to ensure safety
before replacing a Unit. With the above Relay Terminal Block, a Controller
Link Unit can be replaced by turning OFF only the specific Unit being
replaced, i.e., without turning OFF any other Units. The communications
cables are left connected to the Re lay Ter m inal Bl ock and only the Re lay Terminal Block is removed from the Controller Link Unit. (The built-in ter mina tin g
resistance connected at the Units at the end of the network prevents using the
Relay Terminal Bl ock on the end Units.) Refer to

• When CS1W-CLK21-V1 and CJ1W-CLK 21-V1 Units are used with other
models in the same network, set the node addresses of all nodes to
between 1 and 32. It is not possible to construct a net work that uses a
node address higher than 32 in a network that includes pre-version-1
models.
Turn OFF the Wired Network 62 Node Enable Bit (bit 11 of D30000 + 100
× Unit No.) in the DM Parameter Area software switch of all CS1WCLK21-V1 and CJ1W-CLK21-V1 Units to restr ict the netw or k to 32 no des
max. If a different value is specified, the network will be incorrectly configured.
• To construct a network that uses a node address higher than 32, it is necessary for all nodes to be CS1W-CLK21-V1 or CJ1W-CLK21-V1 Units.
In addition, the W ired Network 6 2 Node Enab le Bit in the DM Parame ter
Area software switc hes of all nodes mu st turned ON to enabl e 62 nodes
maximum. If a different value is specified, the network will not be correctly
configured.
Application PrecautionsSection 1-5
• The Wired Networ k 62 Node Enable Bit in the DM Parameter A rea software switches of CS1W-CLK21-V1 and CJ1W-CLK21-V1 Units is read
when the Unit is restarted.
• When using automatic data link creation with 1:N allocation, all nodes
must be CS1W-CLK21-V1 or CJ1W-CLK21-V1 Controller Link Units.
Other models cannot participate in data links that employ 1:N allocations.
• Communicate between the CP U Unit and Communicati ons Units by executing the SEND(090) , RECV(098), and CMND(490) in structions for the
internal logic ports (8 ports max.). Up to eight Controller Link Units can be
connected to a single CPU Unit with unit version 1.2 or later. Perform
exclusive control of the ports using the ladder program when using the
SEND(090), RECV(098), and CMND(490) instructions to perform message servic ing on multiple networks (Units ).
• Up to 20,000 data li nk sen d and receive words can be allocated per node
(Unit) when using unit version 1.2 or later. Data of 20,000 words is divided
and refreshed across three CPU Unit cycles. Make sure that the response
time has been consid ered in the s ystem design. ( Data is synchr onous for
each node when data is refreshed in the CPU Unit, in the same way as for
earlier versions. If the number of data link words is 12,000 words or less,
the response with earlier unit v e rsi ons (pre-Ver . 1.2 ) is exactly the same.)

terminal block.
1,2,3...1. Peel back the cover of the cable for about 50 mm without scratching the
mesh of the shield. Do not pee l too much bec ause it may cause a shor tcircuit.
2. Twist the mesh of the shield to form a line.
3. Leave the tip of the wire created by twisting the shield exposed an d cover
the remaining section with a heat-shrinking tube.
