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:

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 CQM1HCLK21) must be installed as follows:

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-distance wiring, and partial conversion to optical fiber. (Refer to the CS1W-

CLK12, CVM1-CLK12 Optical Ring Controller Link Units Operation Manual

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.

Message Service

This function controls data transmission with particular nodes, reading or writing of status data, changing of operation modes, etc., by executing communications instructions on a program. The communications instructions include SEND/RECV instructions for data transmission and CMND instructions for issuing various commands.

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 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.

Network Status Area Other than the Data Link: The network status such as the state of node participation is reflected in the status area of the PLC.

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.

Item Specifications

Number of send words per node

Number of send and receive words per node

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.

1,000 max.

C200HX/HE/HG, CVM1, CV-series, and CQM1H-series PLCs: 8,000 max. CS/CJ-series PLCs: 12,000 max.

IBM PC/AT or compatible: 32,000 max. (PCI or ISA Board)

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.

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 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 to enable a maximum of 62 nodes.

Restrictions

The maximum 62 nodes cannot be achieved if version-1 models and pre-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 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

× Unit No. of all nodes

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 in the CX-Programmer version 3.2 or later.

× Unit No. + 12 to 20) in the DM Parameter

Specifications and Configurations Section 1-2

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 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 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.

Specifications and Configurations Section 1-2

Note Normally, the communications cable must be disconnected from a Wired Con-

troller Link Unit to replace it. Doing this, however, will interrupt communications on the network, requiring that all node 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 Relay Terminal Block and only the Relay Terminal Block is removed from the Controller Link Unit. (The built-in terminating resistance connected at the Units at the end of the network prevents using the Relay Terminal Block on the end Units.) Refer to

• When CS1W-CLK21-V1 and CJ1W-CLK21-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 network 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 restrict the network to 32 nodes 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 Wired Network 62 Node Enable Bit in the DM Parameter Area software switches of all nodes must turned ON to enable 62 nodes maximum. If a different value is specified, the network will not be correctly configured.

Application Precautions Section 1-5

• The Wired Network 62 Node Enable Bit in the DM Parameter Area 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.

Data Links Procedures Section 2-1

Note a) When using fewer than 33 nodes, make sure that the Wired Net-

work 62 Node Enable Bit if the DM Parameter Area software switch is turned OFF to restrict the network to 32 nodes maximum. To construct a network containing more than 32 nodes, all nodes must use the CS1W-CLK21-V1 or CJ1W-CLK21-V1.

b) Be sure that the data link mode in the data link parameters in the

DM Area is set to 00 when using manually set data links.

c) When using the 8-bit storage format, make sure that the relevant

locations in the DM Parameter Area are set to 0. The storage format used by all models other than CS1W-CLK21-V1, CS1WCLK21, CJ1W-CLK21-V1, and CJ1W-CLK21 is fixed at 8-bit, regardless of the setting.

Note 1. Always turn OFF the power to the PLC before connecting the communica-

tions cables.

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 terminal, always use the appropriate 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 length of peeled cable during installation according to the crimp terminal used and make sure that the peeled length is not too long. Cover the compressed section of the crimp terminal 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 from other nodes. Be sure not to pull on the signal lines.

work, but we recommend full-lock connectors to prevent accidental disconnections during operation.

2. The maximum distance between nodes is slightly shorter for connectors with crimp-cut cables compared to connectors assembled with adhesive. Also, the maximum distance is reduced due to extension loss when Inline Adapters are used to extend cables.

Note 1. Repeater Units must be supplied with 24-V DC power.

2. Wire-to-Optical Repeater Units (CS1W-RPT02 and CS1W-RPT03) are used to convert a section of a wired network to optical fiber. Two Units are always used as a single set. Wire-to-Optical Repeater Units cannot be connected to Optical Ring/Optical Controller Link Units or Support Boards. If these types of Controller Link Units or Support Boards are connected by mistake, communications errors will occur throughout the network.

3. Repeater Units have a baud rate switch and a terminating resistance switch. The same baud rate must be set for all nodes on the network. In addition, the terminating resistance switch of Units (Controller Link

Wired Network 62 Nodes Enable Bit 0: 32 nodes max. 1: 62 nodes max.

4. Repeater Units can be connected in a network in advance if new nodes are to be added to the network after the system has been constructed. When it becomes necessary to add a node, cabling can be accomplished easily by simply wiring a T-Branch to the Repeater Unit. This method also allows nodes to be added without stopping communications over the existing network.

3-4-1 Segments

Repeater Units divide a wired Controller Link network into segments. Segments are comprised of nodes connected in a multi-drop configuration using wire cables. The specifications of the network within a segment are identical to the wired Controller Link network itself. The specifications within a single segment are shown in the following table.

Because Repeater Units enable up to 2 stages to be connected, the maximum transmission distance of a network (i.e., the total length of the longest path connecting any two nodes) is as follows:

Repeater Units do not use a node address.

3-4-2 Number of Repeater Units

The number of Repeater Units that can be connected in a Wired Controller Link Network depends on the mode of connection.

When Repeater Units are used, a maximum of 32 Units, including Controller Link Units/Support Boards and Repeater Units, can be connected within a single segment.

Moreover, if Repeater Units are used for T-Branch wiring, long-distance wiring or partial conversion to optical fiber, up to two repeater stages (see note below) can be connected. Connect Repeater Units so that they do not exceed these ranges.

: Controller Link Unit/Support

Board

: Wire-to-wire Repeater Unit

: Wire-to-optical Repeater Unit

(two Units used in a pair)

: Range of a single segment

Note: The Repeater Unit will be

counted in the number of nodes for each segment that it is connected to.

Note The maximum number of repeater stages refers to the maximum number of

Repeater Units that can be inserted into the path connecting any two nodes. In other words, it is necessary to connect Repeater Units so that no more than two Repeater Units (two stages) need to be passed for any node within a network to reach any other node. With Wire-to-Optical Repeater Units, two Units make up a single set, which is counted as a single stage.

Examples of Correct Repeater Unit Connections

Stage 1

Not more than 2 Repeater Units (2 stages) must be passed for any node to reach any other node

More than 2 Stages of Repeater Units

CS1W-RPT01 Repeater Unit

Constructing Networks with Repeater Units Section 3-4

The path from one node to another travels via three Repeater Units (3 stages). This kind of network is NOT allowed.

Note If the Repeater Units are used incorrectly, communications errors may occur,

or nodes may not be able to participate in the network.

3-4-3 Terminating Resistance

In a Wired Controller Link Network, turn ON the terminating resistance switches only at the nodes at both ends of the network.

When Repeater Units are used to divide the network into multiple segments, turn ON the terminating resistance switches of the nodes at both ends of each segment. When a Repeater Unit is connected to the end of a segment, turn ON the built-in terminating resistance switch of the Repeater Unit itself.

Connection examples are shown below.

Note When constructing a network using Repeater Units, each segment must sat-

isfy all of the following requirements:

• The total number of Controller Link Units, Support Boards, and Repeater Units within a single segment must not exceed 32.

• The total cable length of a single segment must not exceed the specified value. (500 m at 2 Mbps; 800 m at 1 Mbps; and 1 km at 500 Kbps.)

• The maximum number of repeater stages that can be inserted into the path connecting any two nodes is two.

• The node at each end of a segment (including Repeater Units) must have terminating resistance turned ON.

• The baud rates within each segment must be set to the same value.
