The output blocks that transfer Area 1 and Area 2 data from the CompactLogix to
the MVI69-FLN module (blocks 1 to 38) update the Upper Layer Status through
word offset 247. The sample ladder logic uses the
FLNETMODULE.CONTROL.UpperLayerStatus controller tag to update the upper

You can monitor the Upper Layer Status from the Display Own Node Status
command in the Configuration/Debug menu.
