Data Links

This section outlines data links and the method of setting data link tables when using data
links. For details, refer to the Controller Link Support Board Operation Manual (W307), Con-
troller Link Unit Operation Manual (Cat. No. W309), and the Controller Link Support Board for
PCI Bus Operation Manual (Cat. No. W383).
What Are Data Links?
Data links automatically exchange preset data between nodes (i.e., between PLCs, between
a PLC and an IBM PC/AT or compatible computer, or between a PLC and an NS-series PT).
Data links can be freely created for CS-series PLCs, C200HX/HG/HE PLCs, CVM1, CV-
series PLCs, CJ-series PLCs, CQM1H-series PLCs, and NS-series PTs.
Two data link areas, area 1 and area 2, can be set for each node. Data links can be set in ei-
ther of the following ways.
• Data link areas can be set by inputting data link tables through the Controller Link Support
Software. Data link tables are created to define the data links. These tables enable free al-
location 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.
Automatic setting and manual setting cannot be used together in the same network.
The following rules apply to these methods of setting data links.
1. Data links are enables concurrently for area 1 and area 2.
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.
3. Not all nodes must participate in the data links.
Model Remarks
Required to connect PLC with
Controller Link Network.
Required to connect IBM
PC/AT or compatible com-
puters with Controller Link
Network.
Required to connect the PT,
PLC, and IBM PC/AT or com-
patible computers. Use
shielded twisted-pair cable.
Used as a relay terminal block
for wires and can be used as
required to facilitate replace-
ment and maintenance of Con-
troller Link Units and Boards
after the communications sys-
tem has been started.
