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 17: 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 18: 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 19: Applications Precautions
Applications Precautions • Locations subject to shock or vibration. !Caution Take appropriate and sufficient countermeasures when installing systems in the following locations: • Locations subject to static electricity or other forms of noise. • Locations subject to strong electromagnetic fields. •...
Page 20 Applications 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.
Page 21: 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 22 2) for EMS but, depending on the backup power supply used, they may not conform to the standard for immunity to surges (IEC61000-4-5). In order to ensure conformance, either use an OMRON S82K-series power supply, which is the recommended backup power supply, or take surge counter- measures at the primary side.

Page 25: 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 28 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 29 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 34 Overview Section 1-1 Two Controller Link Units that are used in duplex operation are treated as just one node in the Controller Link Network and can be used in the same way as pre-version 1 models (i.e., without “-V1” at the end of the model number). The operating status of the active Controller Link Unit is constantly stored in the standby Controller Link Unit and so operation continues smoothly if there is an active/standby switchover between the Units.

Page 153: Checking Data Link Status
Section 5-4 Checking Data Link Status Checking Data Link Status There are two methods for checking the status of active data links: • Check the LED indicators on the front of the Units. • Check the data link status area. When using Controller Link Units in duplex operation, check the data link operating status at the active Controller Link Unit.
Page 154 Section 5-4 Checking Data Link Status The number of words used for data link status, and the information that is reflected, depends on the setting (8-bit or 4-bit format) for the data link status storage format specification in the DM parameters area, as shown in the fol- lowing diagram.

Page 159 Section 5-4 Checking Data Link Status Note The network uses the data link storage format setting that is set in the startup node. Therefore, if multiple nodes are set as startup nodes, make sure that they all have the same settings. If the settings are different in each startup node, the data link storage format setting used will depend on the startup node.

It is always possible that the message may be lost in transit due to noise or some other condition. When using the message service, it is advisable to prevent this situation from occurring by performing resend processing at the node where instructions are issued.

Section 8-2 Duplex Unit System Configuration If there is an active/standby switchover due to one the reasons above, a duplex communications error is detected at the CPU Unit, and the corre- sponding Duplex Communications Switched Flag (A43600 to A43615: bits 00 to 15 correspond to the unit number) turns ON.
Page 226: Duplex Specifications
Section 8-2 Duplex Unit System Configuration Note 1. CS1D Systems require special CPU Units, Backplanes, and Power Supply Units. For details, refer to the CS-series Duplex System Operation Manual (W405). 2. When using duplex Communications Units, use the duplex Controller Link Units shown in the illustration above.
Page 227: Procedure For Using Duplex Units
Section 8-3 Procedure for Using Duplex Units It is also possible to use only some of the Units in the Controller Link Net- work in duplex operation. In this case, up to a total of 62 active and standby Controller Link Units and Controller Link Units that are not used in duplex operation can be connected.
Page 228 Section 8-3 Procedure for Using Duplex Units After transferring the PLC Setup settings, reset the CS1D’s power supply. For details on the operation method, refer to 8-3-2 Duplex Settings in the PLC Setup. Note (a) If the duplex settings in the PLC Setup are not performed, it will not be possible to create I/O tables.
Page 229 Section 8-3 Procedure for Using Duplex Units 1) In the PLC Setup’s duplex settings, make the Communications Unit duplex setting for the corresponding unit number. Also, after transferring the PLC Setup settings, reset the CS1D’s power supply to enable the settings. 2) Set the same unit number for the two Duplex Units.

Page 241: Communications Mechanism
Section 9-1 Communications Mechanism 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 242: 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 243: Network Parameters
Section 9-1 Communications Mechanism 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.
