Setting Data Links Section 5-2
Words N+22 through N+25 register nodes that will participate in the data
links. The numbers shown in the table are the node addresses. The bit status
for each node address indicates whether the node is to participate in the data
links.
Participate: ON
Not participate: OFF
Note When using automatic data link creation with 1:N allocations, set DM Parame-
ter Areas words N+2 to N+11 (which were previously used for automatic set-
ting with equality layout) to 0.

Item Setting range
Data link mode Specify automatic data link creation with 1:N allocations.
1:N allocation Specify Common type.
Start word for area 1 Set the word address in BCD.
CIO Area: 0000 to 6143
LR Area: LR 000 to LR 199 (CIO 1000 to CIO 1199) (See
note.)
DM Area: DM 00000 to DM 32767
EM Area: Banks 0 to 12: EM 00000 to EM 32767
Note: When a word between LR 000 and LR 199 is spec-
ified, the data link area will be allocated between words
CIO 1000 and CIO 1199 in the CIO Area.
Area for area 1 Set the area for data link area 1 as a hexadecimal num-
ber.
CIO Area: 80 hex
LR Area: 86 hex
