Operation

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.
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 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 and an error message will be displayed saying that the tables cannot be
edited during data link operation.
Method
This function can be set using the CX-Net in CX-Programmer version 3.2 or
later.
Objectives
• In systems that operate non-stop and cannot be turned OFF, this function
makes it possible to change data link tables to accommodate the addition
of new nodes and to transfer data link tables without having to stop manu-
ally set data link communications.
• If this function is combined with the use of token-ring mode to add net-
work 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.
