Creation with 1:N
Allocations
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.

Applicable Models:
• CS1W-CLK12-V1 and CS1W-CLK52-V1 Controller Link Units with lot
numbers 0306@@_@@@@ or later (manufactured after May, 2003).
• CS1W-CLK13/53
• 3G8F7-CLK13/12-V1/53/52-V1
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
Method
Allocation addresses and sizes are all specified using the Automatic Data Link
Creation Parameters (D30000 × Unit No. + 12 to 20) in the DM parameters
area. These values can be set using the CX-Net in CX-Programmer version
3.2 or later.
Objective
This function is effective in applications that collect data from slave PLCs into
a master PLC.
