CHAPTER 10 – Data Links
Automatic Settings
Automatic settings can be used for simple data exchanges involving fixed allocations, when all nodes are set for
the same send size and the same data is to be shared among all nodes in order of node address.
Using a Programming Device (such as the CX-Programmer or a Programming Console), set the data exchange
method in the DM parameter area of the startup node.
This section describes how to perform Controller Link and SYSMAC LINK operations from creating data link
tables to starting up the data links.
