10-2 Changing the Data Link Tables with Active Data Links

10-2-1 Overview

The data link tables can be changed and data link tables can be allocated for newly added nodes while the system’s data links are active if the following Controller Link Units and Support Boards are used.

Models that Support Data Link Table Changes during Active Data Links

Model	Remarks

CS1W-CLK21-V1	Wired Controller Link Unit for CS-series PLCs

CJ1W-CLK21-V1	Wired Controller Link Unit for CJ-series PLCs

3G8F7-CLK21-E-V1	Wired Controller Link Support Board for PCI Bus

Note 1. When using Controller Link Units and Support Boards that are not listed in the above table, data link tables cannot be changed while data links are ac- tive.

2.CX-Programmer version 3.2 must be used to change data link tables with active data links. CX-Programmer version 3.1 or lower versions cannot be used.

10-2-2 Example of Changing Data Link Table with Active Data Links

System Configuration at Startup	System Configuration after Adding Nodes
CS1W-RPT01	CS1W-RPT01
Repeater Unit	Repeater Unit	Newly added nodes
Data Link Area	Data Link Area

Without stopping the data links, the data link tables can be changed to exchange data link data with the new nodes.

10-2-3 Operations when Changing Data Link Tables

The Controller Link Unit/Support Board that receives the command from the CX-Programmer version 3.2 or higher to change a data link table with active data links will temporarily stop refreshing data with the PLC, change to the new data link table (data link refresh allocation) and then resume refreshing data links.

Nodes with data link tables that are changed will send the data from immedi- ately before the tables were changed while PLC data link refreshing is stopped.
