What Are Data Links?
Section 5-1
can be used first, and then the send size of each node and other set-
tings can be changed as required.
Using Offsets
For automatically set data links, all of the send words transmitted by a node
are received by other nodes with no change in size. For manually set data
links, the size of a receive area can be restricted by specifying a number of
words from the beginning word of the words sent by another node.
However, the above system does not guarantee that only the desired words
will be received and therefore the receive node may receive unnecessary
data.
Offsetting enables specification of a more specific range of receive data by
indicating both the number of words and the starting word position from the
beginning of the area. The offset refers to the starting word position counted
from the beginning of the area.
