Omron CS1W-RPT01 Features, Twisted-pair Cable or Optical Fiber Cable Connection, Specifications

Overview Section 1-1

1-1-2 Features

The Controller Link Network has the following features to meet the various requirements of FA sites.

Data Links

Flexible and efficient data links can be created for large capacities of data as listed below.

Item	Specifications
Number of send words	1,000 max.
per node
Number of send and	C200HX/HE/HG, CVM1, CV-series, and CQM1H-series PLCs: 8,000 max.
receive words per node	CS/CJ-series PLCs:
	Pre-Ver. 1.2: 12,000 words max.
	Unit Ver. 1.2 or later: 20,000 words max.
	IBM PC/AT or compatible: 32,000 max. (PCI or ISA Board)

Data links can be automatically set, or they can be set by the user to freely change the sizes of the data areas used. A data link can also be created so that one node receives only part of the data sent from another node. This function enables users to receive only the required data, thereby increasing data link efficiency.

Data link tables for which the number of send and receive words exceeds 12,000 words can be set using CX-Net in CX-Programmer Ver. 5.0 or higher.

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 cables or optical fiber cables. Select the system that suits your application.

Features of Twisted-pair Cable

Twisted-pair cable is easy to connect and maintain. The cable can be pro- cessed much more easily than coaxial or optical cable, thereby reducing the cost of tools and assembly time.

Connections are made to a terminal block on the Controller Link Unit and to a special connector on the Controller Link Support Board for easy system assembly and modification.

The network is equipped with the required terminating resistance built into the Units allowing the terminating resistance to be easily set at both ends of the network using a simple switch.

Features of Optical Fiber Cable

Optical Fiber Cable has superior noise resistance, so this system can provide highly reliable communications even in very noisy conditions.

The communications distance can be up to 20 km total (1 km max. between nodes) if H-PCF cable is used and up to 30 km total (2 km max. between nodes) if GI cable is used, which allows long-distance or large-scale net- works.

Once the Optical Fiber Cable has been fitted with special connectors, the cables can be easily connected or disconnected.
