Data Link Area Allocations Section 4-6
It is still necessary to set the total data link words for group 1 and group 2 to
within the maximum number of link words (2,966 words).
4-6-3 Refreshing Data Links with Automatic Settings
Data link refreshing with automatic settings is carried out for all nodes in the
data link areas that have been specified.
In the following example, only nodes 2, 4, 5, and 6 are participating in the data
links. Nodes 1, 3, 7, and 8, however, will also be refreshed and words for them
cannot be used for other applications. If no data is received, nodes 1, 3, 7,
and 8 are refreshed with 0.
Refreshing for the above setup will be as shown below:
Note When using the SYSMAC LINK Units listed below, the node areas outside of
the node address allocated the lowest word addresses (node 2 in the above
example) and the node allocated the highest word addresses (node 6 in the
above example) are not refreshed (nodes 1, 7, and 8 in the above example),
and can be used for other applications in the CPU Unit of these SYSMAC
LINK Units.
