3 Safety Precautions

!WARNING Do not attempt to take any Unit apart while the power is being supplied. Doing
so may result in electric shock.
!WARNING Do not touch any of the te r minals o r ter minal blocks while the power is bein g
supplied. Doing so may result in electric shock.
!WARNING Provide safety measures in external circuits (i.e., not in the Programmable
Controller), includin g the following items, to ensure safety in the system if an abnormality occurs due to malfunc tion of the PLC or anoth er external factor affecting the PLC operation. Not doing so may result in serious accidents.
• Fail-safe measures must be taken by the customer to ensure safety in the event of incorrect, missing, or abnorm al signals caused by broken signal lines, momentary power interruptions, or other causes.
• Emergency sto p cir cuits, inter lock circui ts, limit circu its, and sim ilar safety measures must be provided in external control circuits.
xx
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. As a counterme asure for such errors, external safety measures must be provided to ensure safety in the system.
• The PLC outputs m ay remain ON or OFF due to depos ition or bur ning of the output relays or destr uction of the output transistors. As a cou nter­measure for such problems, extern al safety measures must be provide d to ensure safety in the system.
• 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 b eing 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. Other wise, the input signals may not be readable.
!Caution Confirm safety at the destination node before transferring a program to
another node or changing c ontents of the I/O memory ar ea. Doing either of these without confirming safety may result in injury.

1-1 Overview

1-1-1 What Is the Controller Link?

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.) The functions of a Controller Link Network are illustrated below.

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 Setting Used 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 Setting Used 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/RECV The 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.
CMND The 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 Area Data Link Status Area
When the data link function is used, the data link status is reflected in the data link status area of the PLC.

1-1-2 Features

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.
Item Specifications
Number of send words per node
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.

Overview Section 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
Overview Section 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.

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
× Unit No. of all

Specifications and Configurations Section 1-2
Method
Allocation addresses and sizes are all specified using the Automatic Data Link Creation Parameters (D30000 Area. These values can be set using the CX-Net i n the CX-Pro grammer ver­sion 3.2 or higher.
Objective
This function is effective in applica tions that col lect da ta from sl ave PLCs into a master PLC.
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 fail with an error message saying that t he ta bles cann ot be ed ite d during data link operation will be displayed.
× Unit No. + 12 to 20) in the DM Parameter
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-

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 Precautions Section 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.)
• For details on Controller Link Unit current consumption, refer to

Note 1. Always turn off power to the PLC before mounting the Controller Link Unit
into the Backplane or connecting the Bus Connection Unit.
Unit Installation Section 3-2
(
)
2. Be sure that all screws on the Backplane, the Bus Connection Unit, the ter­minal block, and cables are tightened firmly. If screws work loose, a mal­function may occur as a result of vibration.
3. A label has been placed over the upper surface of the Controller Link Unit to prevent scraps of wire from entering the Unit. Conduct wiring and instal­lation with this label in place. If wire scraps get into the Unit, it will malfunc­tion.
4. Remove the label after wiring and installing the Controller Link Unit to pre­vent overheating. Overheating will cause the Unit to malfunction.

2. Always use a crimp terminal for wiring. If a wire that has only been twisted is connected directly to a terminal block, short circuit, malfunction and product damage will result.
3. Use the recommended crimp terminals.
4. When mounting the crimp term inal, always use the appropri ate tools for each crimp terminal and follow the appropriate installation procedures. Contact the crimp terminal manufacturer for details on the appropriate tools and procedures. Failure to use the appropriate tools and procedures could cause cables to break.
5. Measure the len gth of peeled cable during install ation according to the crimp ter mi nal use d an d make sure th at th e pee led len gth i s no t too long . Cover the compressed section of the crim p termin al and cable with vinyl tape or heat-shrinking tube.
6. Be sure not to confuse the signal lines and shield line connections.
7. Tighten the screws on the terminal block firmly. The correct tightening torque is 0.5 N·m.
8. If a signal line disconnects from the terminal, either the Unit will be unable to communicate with other nodes on the network or that section of the net­work will be isolated fr om other nodes. Be sure not to pul l on the signal lines.
