Setting Data Links
Section 5-2
Note a)
The total number of words in data link send and receive areas
must not exceed 20,000 per node when using Controller Link
Units with unit Ver. 1.2 or later, or 12,000 words per node if using
pre-Ver. 1.2 Controller Link Units.
b)
The following values must be satisfied for each node for the data
link area 1 and area 2 so that the final word in the data link does
not go beyond the last word in the PLC memory area.
(Data link start word – 1) + (Total number of send/receive
words in area 1 or area 2)
≤
6143 (CIO Area)
199 (LR Area)
32767 (DM Area, EM Area)
c)
Refer to the
Controller Link Support Boards Operation Manual
(W307)
for information on the Controller Link Support Board.
d)
If CX-Net detects an error during the data link table check, trou-
bleshoot the error referring to
9-4 Troubleshooting Error Mes-
sages in CX-Net Data Link Table Check
.

Area 2
Data link
start word
CIO Area: CIO 000 to CIO 6143
LR Area:
L
R 00 to LR 199 (*)
DM Area:
DM 0000 to DM 32767
EM Area:
Banks 00 to 15, EM 0000 to EM 32767
(EM must be installed)
Unit Ver. 1.2 or later: The same memory areas can be set for
both Area 1 and Area 2.
*: When a word between LR 000 and LR 199 is specified, the
data link area will be allocated between CIO 1000 and
CIO 1199.
Number of
words
Remote nodes: 0 to the number of source words
Set the number of words to be received.
0 to 4,000 (CS1W-CLK23, CJ1W-CLK23)
Local node:
CS1W-CLK23, CJ1W-CLK23: 0 to 4,000
CS1W-CLK21-V1, CJ1W-CLK21-V1: 0 to 1,000
Set the number of words to be transmitted.
The total number of words in area 1 and area 2 in each node
must not exceed 4,000 for the CS1W-CLK23 or CJ1W-CLK23,
and must not exceed 1,000 for the CS1W-CLK21-V1 or CJ1W-
CLK21-V1.
The numbers of words in both area 1 and area 2 in each node
must not be set to 0.
Offset
Remote nodes: 0 to one less than number of source words
Set the offset for the data to be received.
Local node:
Cannot be set.
This setting is not required if an offset is not used.
Setting item
Setting range

Setting range
PLC model
Set the model of the PLC’s CPU Unit.
Nodes
1 to 32
Set the address of the refresh nodes.
It cannot be set to a parameter exceeding the “maximum node
address” of the network parameter.
