Setting Data Links Section 5-2
Note a) The total number of words in data link send and receive areas
must not exceed 12,000 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
≤
6143 (CIO Area)
199 (LR Area)
32767 (DM Area, EM Area)
c) When using Area 1 only, set the data link start word, type, and the
number of send words of Area 2 to 0.
d) When using Area 2 only, set the data link start word, type, and the
number of send words of Area 1 to 0.
e) The startup node must be set as a participating node of the data
links. If not, the data links will not start.
Area 2 type Set the area type for Area 2 in BCD.
DM Area: 82 Hex
EM Area: Banks 00 to 07: 90 to 97 Hex
Banks 08 to 12: A8 to AC Hex
Area 2 not used: 00 Hex
Number of send words
per node of Area 2 Set the number of words in BCD between 0 and
1,000.
The total number of send words of Area 1 and Area
2 must not exceed 1,000.
When Area 2 is not used, set to 0.
First data link status word Set in BCD the first word used for storing data link
status. An area of 16 words is used for storing sta-
tus.
0 (*), IR 000 to IR 6128
Status is stored in an the IR Area only.
*: When 0 is set, the status is saved in IR 1500 +
unit number x 25 (+ 7 to + 22).
Nodes to participate in
the data links Set to ON (1) the bits corresponding to the nodes
participating in the data links.
The data link will not start unless the startup node
itself is set as a participating node.
The data link will not start if the node is set to a
parameter exceeding the “maximum node address”
of the network parameter.
