Setting Data Links
Section 5-2
Note
1.
The total number of words in data link send and receive areas must not ex-
ceed 8,000 per node.
2.
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)
≤
2555 (CIO Area)
199 (LR Area)
8191 (DM Area for CV500/CVM1-CPU01)
24575 (DM Area for other CPU Units)
32765 (EM Area)
3.
Refer to the Controller Link Support Boards Operation Manual (W307) for
information on the Controller Link Support Board.
Precautions
• When data links are automatically created for networks containing CS-
series PLCs, CVM1, and CV-series PLCs, the linkable area is restricted to
the area of the CVM1, CV-series PLC because it is smaller than that of
CS-series PLCs.
Area 2
Data link
start word
CIO Area:
CIO 0000 to CIO 2555
LR Area:
LR 000 to LR 199 (*)
DM Area:
DM 0000 to DM 8191 (CV500/CVM1-CPU01)
DM 0000 to DM 24575 (Other CPU Units)
EM Area:
Banks 00 to 07, EM 0000 to EM 32765
(EM must be installed)
The same area cannot be set for both Area 1 and Area 2. Set
different areas.
*:
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.
Local node:
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 1,000.
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.
