Data Link Table Examples
Common Link Parameters
Refresh Parameters
Node #2
These parameters are set from a SSS/CVSS, and need to be set only once for a
SYSMAC LINK Network. Enter the communications cycle time and the number
of DM and LR Area link words for each node in the data link, as shown below.
(Setting the number of LR Area link words to zero for node 8 means that node 8
will be able to receive but not send data.)
With manual data link table generation, the number of link words sent from each
node can be set in 1 word increments.
These parameters are also set from a SSS/CVSS, and need to be set separately
for each node in the data link. Enter the PC model, beginning LR and DM words,
and beginning status word, then set the number of LR and DM link words for the
local node each node that the local node will link to.
The number of LR and DM words set for each node in the common link parame-
ters will be allocated to nodes automatically in the order that they have been
entered into the refresh parameters table. Link word allocation starts at the
beginning LR and DM words. The order of nodes in the refresh parameters table
can be changed freely.
In node 2, the data link area will be allocated to nodes 2, 5, 6, and 8 in that order,
so the node 2 refresh parameters are set as shown below.
