Note a) N: Unit number
b) Only status for nodes 1 to 6 are saved.
After you have confirmed that the data link function is operating normally,
check to see whether or not the data link is operating as intended, i.e., check
to see if the desired bits/words data is being transferred to the intended words
at other nodes.
Although the data link function itself may be operating correctly, the data link
areas may have been input incorrectly.
Change the contents of a bit or word in a data link send area using a Program-
ming Device or the user program and check whether the change is reflected in
data link areas of other nodes as intended.
Note Do not restart the polling node of the Controller Link Network while data links
are active. Otherwise, the data links may stop.

Data Link Participating Flag
When the source node's data link is participating, the AND condition of the
data link status for each node can be taken using the Data Link Participation
Flag and the Communications Error Flag, and the error output.
