Setting Data Links
Section 5-2
Note a)
The total number of words in data link send and receive areas
must not exceed 8,000 per node.
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
≤
2555 (CIO Area)
199 (LR Area)
8191 (DM Area for CV500/CVM1-CPU01-EV
@
)
24575 (DM Area for other CPU Units)
32765 (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
CQM1H-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-EV
@
)
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 dif-
ferent 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.
Setting item
Setting range
Setting item
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 parameters.
