Node Refresh Sequence
Beginning with the data link start address above, specify which nodes are to
have data refreshed at the local node address and the order in which data is to
be refreshed (i.e., the node refresh sequence). This order will be the same for
Area 1 and Area 2.
(For the local node address, data is sent from the local node area. For a
remote node address, data is received from the remote node address to the
local area.)
Note: • The local node must be included in the refresh nodes.
Example: If 1, 2, 3 is input, node addresses 1, 2, and 3 will be allocated in
order, beginning with the start address.
Click this button to make the values set for the above items the default values
for new data link settings.
