PRECAUTIONS This section provides general precautions for using the Controller Link Unit and related devices. The information contained in this section is important for the safe and reliable application of the Controller Link Unit. You must read this section and understand the information contained before attempting to set up or operate a Controller Link Unit.
Page 21: Intended Audience
It is extremely important that a PLC and all PLC Units be used for the speci- fied 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 PLC System to the above mentioned appli- cations.
Page 22: Operating Environment Precautions
Operating Environment Precautions • 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 countermeasure for such errors, external safety measures must be provided to ensure safety in the system. •...
Page 23: Applications Precautions
Applications Precautions Applications Precautions Observe the following precautions when using the Controller Link Unit. !WARNING Failure to abide by the following precautions could lead to serious or possibly fatal injury. Always heed these precautions. • Always ground the system to 100 Ω or less when installing the system to protect against electrical shock.
Page 24 Applications Precautions • 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.
Page 25 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).

Page 27: Overview
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 Programma- ble Controllers (PLCs), CS-series PLCs, CJ-series PLCs, CVM1 PLCs, CV- series PLCs, CQM1H-series PLCs, and IBM PC/AT or compatible computers.

Page 31 Section 1-1 Overview 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 com- patible computer on the network. Data links do not require the use of commu- nications programs on the PLC (CPU Unit) or IBM PC/AT or compatible computer.
Page 32 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.

Page 35 Section 1-1 Overview • 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.
Page 36 Overview Section 1-1 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 ver- sion 3.2 or higher.

The following Power Supply Unit is recommended: OMRON S82K Series Relay Terminal Blocks The following Relay Terminal Block can be used to make maintenance easier by facilitating replacement of the Controller Link Unit after system operation has begun.
Page 48: Programming Devices
Section 1-2 Specifications and Configurations Note Normally, the communications cable must be disconnected from a Wired Con- troller Link Unit to replace it. Doing this, however, will interrupt communica- tions on the network, requiring that all node be turned OFF to ensure safety before replacing a Unit.

Page 192 SECTION 6 Message Service This section explains how to use the message service provided by a Controller Link Unit. It also explains the FINS commands and responses supported by Controller Link Units and those supported by C200HX/HG/HE, CS/CJ-series, CVM1 and CV-series PLCs. Introduction .
Page 193: Introduction
Section 6-1 Introduction Introduction A message service is a command/response system used for data transmis- sion between nodes on a network, i.e., PLC to PLC, PLC to computer, and computer to PLC). The message service can also be used to control opera- tions, such as mode changes.

It is always possible that the mes- sage may be lost in transit due to noise or some other condition.

Section 8-1 Communications Mechanism Communications Mechanism 8-1-1 Data Transmissions over the Network Controller Link Token (right to send) In a Controller Link Network, token passing is used to control network access. The right to send, called a “token,” circulates around the network. A node that receives the token is allowed to send data.
Page 278: Setting The Polling And Polled Nodes
Section 8-1 Communications Mechanism Check Check Token circulation Polling cycle Token circulation Polling cycle cycle cycle Communications cycle time Communications cycle time Polling Node Each Controller Link Network always has a Unit that controls communications within the network. This Unit is called the “polling node.” Normally, the node that has the smallest node address in the network is the polling node (see note).
Page 279: Network Parameters
Section 8-1 Communications Mechanism If the node is always to be connected as a polled node when the power is turned on, set it as a polled node. If the node can become a polling node when the power is turned on, set it as a polling node. One of the nodes set as a polling node will serve as the actual polling node.

Section 8-2 Communications Cycle Time 8-1-4 Specifying Network Parameters The network parameters can be specified from the Controller Link Support Software. This section describes only the allowable setting range for each net- work parameter. Refer to the Controller Link Support Software Operation Manual (W308) for setting procedures.
