Setting Data Links Section 5-2
SAMPLE2.CLK: Different Allocations to Each Node
Data links can be created so that one node does not receive from all other
nodes or so that some nodes do not send or receive any data at all. In the fol-
lowing example, node 2 does not receive data from node 3 and node 3 does
not receive data from node 1. Node 4 does not send any add; it only receives
data from other nodes.
Data Link Area Structure
Only nodes in which a data link table has been created can participate in the
data links.
In the data link table, the node sequence can be changed freely; however, the
data link areas must be created consecutively.
