Overview
Section 1-1
Method
Allocation addresses and sizes are all specified using the Automatic Data Link
Creation Parameters (D30000
×
Unit No. + 12 to 20) in the DM Parameter
Area. These values can be set using the CX-Net in the CX-Programmer ver-
sion 3.2 or higher.
Objective
This function is effective in applications that collect data from slave PLCs into
a master PLC.
Restrictions
Automatic data link creation with 1:N allocations cannot be performed if ver-
sion-1 models and pre-version-1 models are used together in the same net-
work.
Change manually created data link tables during data link operation.
Overview
It is possible to modify a manually created data link table while data links are
running.
Note
This is possible only with manually created data link tables. Any attempt to
change automatically created data link tables when data links are running will
fail with an error message saying that the tables cannot be edited during data
link operation will be displayed.
Method
This function can be set using the CX-Integrator.
Objectives
• In systems that operate non-stop and cannot be turned OFF, this function
makes it possible to change the data link table to accommodate the addi-
tion of new nodes and to transfer data link tables without having to stop
manually set data link communications.
• If this function is combined with the use of Repeater Units to add network
nodes, it becomes possible to construct systems of greater flexibility.
Operation
When a node is being modified online, this function temporarily stops refresh-
ing of data link data until modifications have been completed.
Nodes will participate in data links after changes to the data link table have
been completed.
Overview of CS1W-CLK23 and CJ1W- CLK23 Features and Functions
The CS1W-CLK23 and CJ1W-CLK23 are upwardly compatible with the
CS1W-CLK21-V1 and CJ1W-CLK21-V1, respectively.
The following link functions have been added to the features and functions of
the CS1W-CLK21-V1 and CJ1W-CLK21-V1.
All other functions and performance are the same as for the CS1W-CLK21-V1
and CJ1W-CLK21-V1.
