Data Link Area Allocations Section 4-6
4-6 Data Link Area Allocations
Data link area allocations when the data link functions are started up are car-
ried out as shown below, depending on whether the startup node data link
table has been set automatically or by the user.
4-6-1 Automatic Settings
All nodes are allocated the same data link area depending on the number of
link words set in the startup node. When automatic allocations are made, the
settings in nodes other than the startup node are invalid. Send word data for
each node is sent to the receive words allocated to the same memory area
words at the other nodes, and stored there. The shaded areas in the following
diagram indicate the send words for each node.
4-6-2 Manual Settings
The data link areas can be allocated as described in this section by using the
refresh parameter settings for each node.
Identical Allocations for
All Nodes When editing data link table refresh parameters, set the same refresh param-
eters for all nodes. (Create refresh parameters for each node using the Sup-
port Software, even if the allocations are the same for all nodes. A copy
function is supported that will make identical settings easy.)
