Checking Data Link Status
Section 5-4
The following example shows an error output program for cases where the
local node data link stops.
The local node's Communications Error Flag (in the data link status area) will
be turned ON if the local node is isolated from the network while the data link
is active. In this case, the data link remains active, so the node's Data Link
Participation Flag will remain ON even though the node is isolated from the
network.
