Area 2 Data link CIO Area: CIO 0000 to CIO 2555
start word
LR Area:
DM Area: DM 0000 to DM 8191 (CV500/CVM1-CPU01-EV@)
EM Area: Banks 00 to 07, EM 0000 to EM 32765
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 Remote nodes:
words
Local node:
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:
Local node:
This setting is not required if an offset is not used.
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
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 .
