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