Overview
Section 1-1
• If Repeater Units are installed at likely future branch points in the network
in advance, new nodes can be added by simply connecting them to these
Repeater Units.
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.
The maximum number of nodes can be extended to 62 for wired networks.
By combining version-1 Controller Link Units/Support Boards and a Repeater
Unit, it is possible to construct networks containing up to 62 nodes.
Improved noise resistance through the use of optical cabling.
By installing two Wire-to-Optical Repeater Units, optical cabling can be used
for sections of the network that are the source of noise.
Devices can be modularized.
• Devices can be modularized according to Repeater Units, making wiring
easier when adding, removing, or modifying devices.
• When starting up devices, components can be added to the network and
debugged as they are completed.
Features and Functions of Version-1 Models
The following features and functions apply to the CS1W-CLK21-V1 and
CJ1W-CLK21-V1 Controller Link Units and the 3G8F7-CLK21-V1 Controller
Link Support Board only.
Up to 62 nodes can be connected.
Overview
When a CS1W-RPT01 Repeater Unit is used, the maximum number of nodes
that can be used in the network increases to 62. (The previous limit was 32.)
Method
Use Repeater Units and turn ON bit 11 (Wired Network 62 Node Enable Bit)
in the DM Parameter Area software switch 100
×
Unit No. of all
nodes to enable a maximum of 62 nodes.
Restrictions
The maximum 62 nodes cannot be achieved if version-1 models and pre-ver-
sion-1 models are used together in the same network.
Automatic data link creation is possible with 1:N allocations.
Overview
It is possible to perform unequal 1:N allocations of data between nodes with
automatic data link creation. This makes it easy to perform data links that for-
merly required the user to manually edit data link parameters.
The following four automatic data link creation patterns can be used:
• Equality layout (the previous pattern)
• 1:N allocation, common type
• 1:N allocation, 1 to 1 type
• 1:N allocation, chain type
