•Connecting or disconnecting any terminal block.
!Caution Failure to abide by the following precautions could lead to faulty operation or the PLC or the system or could damage the PLC or PLC Units. Always heed these precautions.
•Always use the power supply voltages specified in the operation manuals. An incorrect voltage may result in malfunction or burning.
•Take appropriate measures to ensure that the specified power with the rated voltage and frequency is supplied. Be particularly careful in places where the power supply is unstable. An incorrect power supply may result in malfunction.
•Install external breakers and take other safety measures against short-cir- cuiting in external wiring. Insufficient safety measures against short-cir- cuiting may result in burning.
•Disconnect the functional ground terminal when performing withstand voltage tests. Not disconnecting the functional ground terminal may result in burning.
•Do not attempt to disassemble, repair, or modify any Units. Any attempt to do so may result in malfunction, fire, or electric shock.
•Install the Units properly as specified in the operation manuals. Improper installation of the Units may result in malfunction.
•Be sure that all the mounting screws, terminal screws, and cable connector screws are tightened to the torque specified in the relevant manuals. Incorrect tightening torque may result in malfunction.
•Leave the label attached to the Unit when wiring. Removing the label may result in malfunction if foreign matter enters the Unit.
•Remove the label after the completion of wiring to ensure proper heat dissipation. Leaving the label attached may result in malfunction.
•Use crimp terminals for wiring. Do not connect bare stranded wires directly to terminals. Connection of bare stranded wires may result in burning.

•Double-check all wiring and switch settings before turning ON the power supply. Incorrect wiring may result in burning.
•Wire all connections correctly.
•Mount Units only after checking terminal blocks completely.
•Be sure that the Bus Connection Units and other items with locking devices are properly locked into place. Improper locking may result in malfunction.
•Use special packing box when transporting the Controller Link Unit. Handle the product carefully so that no excessive vibration or impact is applied to the product during transportation.
•Check the user program for proper execution before actually running it on the Unit. Not checking the program may result in an unexpected operation.
•Confirm that no adverse effect will occur in the system before attempting any of the following. Not doing so may result in an unexpected operation.
•Changing the operating mode of the PLC.
•Force-setting/force-resetting any bit in memory.
•Changing the present value of any word or any set value in memory.
•Inappropriate settings in data link tables or routing tables can cause unexpected system operation. Always check table settings before starting operation, and always test the settings in trial operation before starting or stopping the data links in actual operation.
•CPU Bus Units will be automatically restarted when routing tables are transferred from a Programming Device to the CPU Unit. Resetting is required to use the new tables. Confirm that restarting the CPU Bus Units will not adversely affect system operation before transferring routing tables.
•Observe the following precautions when wiring the communications cables.
•Separate the cables from the power lines or high-tension lines.
•Do not bend the cables.
•Do not pull on the cables.
•Do not place heavy objects on top of the cables.
•Route cables inside conduits.
•Before touching the Unit, be sure to first touch a grounded metallic object in order to discharge any static build-up.

6 Conformance to EC Directives
The Controller Link Units conform to EMC and Low Voltage Directives as follows:
EMC Directives
OMRON devices that comply with EC Directives also conform to the related EMC standards so that they can be more easily built into other devices or the 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 system used by the customer, however, must be checked by the customer.
EMC-related performance of the OMRON devices that comply with EC Directives will vary depending on the configuration, wiring, and other conditions of the equipment or control panel on which the OMRON devices are installed. The customer must, therefore, perform the final check to confirm that devices and the overall machine conform to EMC standards.
Note Applicable EMS (Electro-Magnetic Susceptibility) and EMI (Electro-Magnetic Interference) standards in the EMC (Electro-Magnetic Compatibility) standards are as follows:
|
EMS |
EMI |
|
|
|
CQM1H-CLK21 |
EN61131-2 |
EN50081-2 |
C200HW-CLK21 |
|
|
|
|
|
CVM1-CLK21 |
|
EN61000-6-4 |
CS1W-CLK21(-V1) |
|
|
|
|
|
CJ1W-CLK21(-V1) |
EN61000-6-2 |
|
|
|
|
Low Voltage Directive
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 CQM1H-
CLK21) must be installed as follows:
1,2,3... 1. The Controller Link Units are designed for installation inside control panels. All Controller Link Units must be installed within control panels.
2.Use reinforced insulation or double insulation for the DC power supplies used for the communications power supply and I/O power supplies.
3.The Controller Link Units that comply with EC Directives also conform to the Common Emission Standard (EN50081-2 or EN61000-6-4). Radiated emission characteristics (10-m regulations) may vary depending on the configuration of the control panel used, other devices connected to the control panel, wiring, and other conditions. You must therefore confirm that the overall machine or equipment complies with EC Directives.

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 the OMRON C200HX/HG/HE Programmable Controllers (PLCs), CS-series PLCs, CJ-series PLCs, CVM1 PLCs, CVseries PLCs, CQM1H-series PLCs, 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.
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: networks connected with shielded twistedpair cable and networks connected with optical fiber cable. Using a Repeater Unit in networks connected with twisted-pair cable makes it possible to use a variety of different wiring configurations, such as T-branch wiring, long-dis- tance wiring, and partial conversion to optical fiber. (Refer to the CS1WCLK12, 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.

Overview |
Section 1-1 |
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. Data links do not require 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), and extended DM Area area (EM area) can be freely set in the send or receive 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 node is the same for all nodes. All nodes participating in |
|||||||
|
the data link share the same data. |
|
|
|||||
Manual Setting |
Used for flexible data link processing depending on each system. |
|||||||
|
Using the Controller Link Support Software, individual 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 freely set. It is also possible to set nodes for |
|||||||
|
only send or receive 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. |

Overview |
|
Section 1-1 |
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 instruction requests the designated node to send area 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 error logs. With the Controller LInk Unit, OMRON’s command |
|
|
protocol called “FINS commands” is used. |
|
Note |
Since the C200HX/HG/HE PLCs do not support the CMND instructions, arbi- |
|
|
trary commands cannot be issued. |
|
RAS |
|
|
|
RAS performs real-time monitoring of the network status. If an error occurs in |
|
|
the network, RAS records and displays the time and contents of the error. |
|
Status Area |

1-1-2 Features
The Controller Link 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.

|
|
|

|
|
Data links can be automatically set, or they can be set by the user to freely change the sizes of the data areas used. 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.
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 your 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 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 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 total (1 km max. between 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.

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 optical 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 Support Board for IBM PC/ATs or compatibles (ISA or PCI bus)
Flexible Inter-network Connections
The Controller Link Network can connect to other networks (Ethernet, SYSMAC NET, SYSMAC LINK, and another Controller Link network) via CVM1, CV-series, CS-series, or CJ-series PLCs. By installing a Communications Unit for the Ethernet, SYSMAC NET or SYSMAC LINK on the same CS/CJ-series or CV-series PLC as a Controller Link Unit, a message service can be created with nodes in interconnected networks through the CVM1 or CV-series PLC. Up to three network levels are possible.
Note CS/CJ-series PLC cannot be connected directly to SYSMAC NET networks and CJ-series PLC cannot be connected directly to SYSMAC LINK networks
The programming and monitoring of other PLCs on the network can be conducted from Programming Devices connected to the PLC’s CPU Unit. Internetwork connections are possible in this case also and can cover up to three network levels.
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 Network, 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.
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.

Overview |
Section 1-1 |
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.
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 the 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 turn ON bit 11 (Wired Network 62 Node Enable Bit) in the DM Parameter Area software switch D30000 + 100 × Unit No. of all nodes to enable a maximum of 62 nodes.
Restrictions
The maximum 62 nodes cannot be achieved if version-1 models and pre-ver- sion-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 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
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 PLCs into a master PLC.
Restrictions
Automatic data link creation with 1:N allocations cannot be performed if ver- sion-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 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 with 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.
