Data Link Area Allocations Section 4-6
Different Allocations for
Each Node To limit receiving from specified nodes and send only or receive only from
specified nodes, change the refresh parameters for each node. In the follow-
ing example, node 5 does not receive data from node 6, and node 6 does not
receive data from node 2. Also, node 8 only receives data.
Note The send area for node 8 has specified 0 for both the CIO Area and DM Area
in the common link parameters.
Only nodes with refresh parameters will participate in the data links.
Although the node order in the manual settings can be changed as you wish,
the Data Link Area must be created in continuous areas.
Creating Two or More Data
Link Groups in One
Network The common link parameters are the same for each network. Consequently,
multiple data link groups cannot be created in a SYSMAC LINK Network. Vir-
tual data link groups, however, can be created using the refresh parameters.
As shown below, if you divide the groups and set the send and receive words
for the nodes within each group, you can set multiple data link groups, as
shown in the following diagram.
