What Are Data Links?
Data links automatically exchange data in preset areas between nodes (PLCs and/or
computers) on a network. Settings can be made either manually or automatically.
CX-Integrator operations can be used for all operations from setting up the PLC
network to controlling data exchange.
Manual Settings
Manual settings enable more flexible allocations, including the send size for each
node, the sequence of nodes for sending and receiving, and the setting of nodes for
sending only or receiving only. Use manual settings to create flexible data links to
meet the requirements of the individual system (e.g., efficient utilization of memory,
restrictions on allocated addresses, etc.).
Data link tables (i.e., tables that define data link area allocations) are generated by
CX-Integrator or network support software (such as Controller Link Support Software),
and sent to all nodes for use.
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.
