This section provides basic information on Controller Link Networks, and will give 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 25: Overview
CJ-series PLC 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 29 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 30 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. trary commands cannot be issued.

Page 32 Overview 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 Flexible Inter-network Connections The Controller Link Network can connect to other networks (Ethernet, SYS- MAC NET, SYSMAC LINK, and another Controller Link network) via CVM1, CV-series, CS-series, or CJ-series PLCs.
Page 33 Overview 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.

Page 129: What Are Data Links
What Are Data Links? What Are Data Links? Data links automatically exchange data in the preset areas between nodes (PLCs and/or computers) on one network. Data links can be freely created for CS/CJ-series PLCs, C200HX/HG/HE PLCs, CVM1, CV-series PLCs, CQM1H-series PLCs, and IBM PC/AT or compatible computers. Two data link areas, area 1 and area 2, can be set for each node.

Manual Setting Options The following options can be set when manually setting data links. Offsets Data of the only the specified number of words can be received starting from the specified word position.

Page 133 What Are Data Links? Using Offsets For automatically set data links, all of the send words transmitted by a node are received by other nodes with no change in size. For manually set data links, the size of a receive area can be restricted by specifying a number of words from the beginning word of the words sent by another node.

Page 271: Communications Mechanism
Communications Mechanism Communications Mechanism 8-1-1 Data Transmissions over the Network 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. If the node has data to send, it will attach the data to the token and send them together.
Page 272: Setting The Polling And Polled Nodes
Communications Mechanism 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 273: Network Parameters
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.

Message Delay Times In this case, the data processing time required for data exchange and the data transmission time are not negligible and need to be included in the calcula- tion. Each time can be determined as follows. Data Processing Time (see page 254.) 0.0025 Data Transmission Time Data transmission time varies with the baud rate.

Page 388: C Using The Relay Terminal Block
Using the Relay Terminal Block This appendix describes how to use the CJ1W-TB101 Wired Controller Link Unit Relay Terminal Block. Using a Relay Terminal Block enables replacing a Controller Link Unit while network communications are still in progress. Appearance Wired Controller Link Unit Relay Terminal Block Relay Terminal Blocks (CJ1W-TB101) can be used on any node but the end nodes to enable replacing the Controller Link Unit with the communications cable connected and turn OFF the power to only the Unit being...
Page 389 Using the Relay Terminal Block Relay Terminal Block Connect the Relay Terminal Block. 4. Attach the terminal block cover to the communications terminal block on the Controller Link Unit. Relay Terminal Block Replacing a Controller Link Unit with a Relay Terminal Block Use the following procedure to replace a Controller Link Unit with a Relay Terminal Block.
Page 390 Using the Relay Terminal Block Note 1. Signal will still be flowing through the communications cables during the replacement procedure if the network is still operating. Use an insulated screwdriver and be very sure that the metal portions of the Relay Terminal Block or the communications cable crimp terminals do not come into contact with any conductive material.
