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)
24575 (DM Area for other CPU Units)
32765 (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 registered as a participating node of the
data links. If not, the data links will not start.
Note
1.
When data links are automatically created for networks containing CS-se-
ries, 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 type
Set the area for Area 2 in BCD.
DM Area:
82 Hex
EM Area:
Banks 00 to 07: 90 to 97 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 status.
0 (*) or CIO 0001 to CIO 2540
Status is stored in the CIO area only.
*: When 0 is set, the status is saved in CIO 1500 + unit num-
ber x 25 (+ 7 to + 22).
Nodes participating in the
data links
Set to ON (1) the bits corresponding to the nodes participat-
ing in the data links.
The data link will not start unless the startup node itself is set
as 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.
