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 13: 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 14: Operating Environment Precautions
Operating Environment Precautions • The PLC outputs may remain ON or OFF due to deposition or burning of the output relays or destruction of the output transistors. As a counter- measure for such problems, external safety measures must be provided to ensure safety in the system.
Page 15: Applications Precautions
• Always turn OFF the power supply or the backup power supply to the PLC or the computer before attempting any of the following. (Online Unit replacement is possible for the CS1W-CLK12-V1 and CS1W-CLK52-V1.) Performing any of the following with the power supply turned ON may lead to electrical shock: •...
Page 16: Conformance To Ec Directives
The Controller Link Units conform to EMC 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).
Page 17 EMC-related performance of the OMRON devices that comply with EC Direc- tives 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.
Page 18 SECTION 1 Features and System Configuration This section provides basic information on Controller Link Networks, and gives the reader an overview of what Controller Link Networks can do and how best to use them. Overview ........... . . 1-1-1 What Is the Controller Link? .
Page 19: 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, CVM1 PLCs, CV-series PLCs, and IBM PC/AT or compatible computers.

Page 22 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 23 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. 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.
Page 24: Features
Duplex Units By mounting the CS1W-CLK12-V1 or CS1W-CLK52-V1 to a CS1D PLC, Con- troller Link Units can be used in duplex operation. If an error occurs at the active Controller Link Unit, the standby Controller Link Unit will take over oper- ation, and communications operation will continue.
Page 25 Overview Section 1-1 Message Service The message service can send and receive up to 2,012 bytes of data (includ- ing 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 cable, H-PCF fiber-optic cable, or GI fiber-optic cable.
Page 26 Greater Reliability with Duplex Communications Units System By mounting the CS1W-CLK12-V1 or CS1W-CLK52-V1 to a CS1D PLC (see note 1), Controller Link Units can be used in duplex operation. The settings for duplex operation can be performed easily.
Page 27 Overview Section 1-1 Used in combination with token-ring mode, Duplex Communications Units allow the creation of communications systems with greater reliability. It is pos- sible to use Duplex Communications Units in token-bus mode, but when an active/standby switchover occurs because of an error in the active Controller Link Unit, or when Units are replaced online, because the system does not have duplex transmission paths, the network is split into two.

Page 201: Communications Mechanism
Communications Mechanism Section 9-1 Communications Mechanism 9-1-1 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 202: Setting The Polling And Polled Nodes
Section 9-1 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 203: Network Parameters
Communications Mechanism Section 9-1 9-1-3 Network Parameters Network parameters are also used to control network operations. Network parameters are read from the polling node and distributed to all other nodes when the Controller Link Network is started. In this way, all nodes on the net- work always have the same network parameter settings.
