Setting Data Links
94
Item
First data link status word Set in BCD the first word used for storing data link status.
Nodes to participate in
the data links
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 PC memory area.
(Data link start word – 1) + Total number of send/receive
words in 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.
Setting range
An area of 16 words is used for storing status.
0 (*), IR 001 to IR 220, IR 300 to IR 496
Status is stored in an the IR Area only.
*: When 0 is set, status of nodes 1 to 6 is stored in
CIO 239 to CIO 241 for level 0 and in CIO 243 to CIO
245 for level 1.
Set to ON (1) the bits corresponding to the nodes partici-
pating 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.
