5-1 What Are Data Links?
CS-series Controller Link Unit Functions by Model
Note

Data links automatically exchange data in the preset areas between nodes
(PLCs and/or computers) on one network. Data links can be freely created for
CS-series, CVM1, and CV-series PLCs, and IBM PC/AT or compatible com-
puters (in token-bus mode only).

Maximum number of send/

Number of send words per

Data Link Area
1. Use the CX-Net in CX-Programmer version 5.0 or higher to set a data links
with more than 12,000 data link send/receive words, or to set data links al-
locating the same area for areas 1 and 2.
2. Use the CX-Integrator to set data link tables with more than 1,000 send
words per node. For information on checking the CX-Integrator version, re-
fer to Checking the CX-Integrator Data Link Setting Tool Version on
page viii.
Two data link areas, Area 1 and Area 2, can be set for each node. Data links
can be set in either of the following ways.
• Data link areas can be manually set by inputting data link tables through
Support Software. Data link tables are created to define the data links.
These tables enable free allocation of data link areas.
• Data links can be set automatically from a Programming Device. With
automatically set data links, all link areas are the same size.
Both automatic setting and manual setting cannot be used together in the
same network. The following rules apply to these two methods of setting data
links.
• Data links are enabled concurrently for Area 1 and Area 2.
• Separate settings (data link start words and send area size) are made in
Area 1 and Area 2. The sequences of send and receive words are the
same in Area 1 and Area 2.
• Not all nodes must participate in the data links.
