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 Control- lers

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, SYS- MAC 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 eight 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 con- ducted from Programming Devices connected to the PLC’s CPU Unit. Inter- network connections are possible in this case also and can cover up to eight network levels.

Use a CS/CJ-series CPU Unit with unit version 2.0 or later and CX-Program- mer Ver. 4.0 or higher to enable internetwork connections for up to eight net- works.

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 Net- work, 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.
