The output blocks that transfer Area 1 and Area 2 data from the ControlLogix to
the MVI56E-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
layer status.
For example, to set a warning condition, set this controller tag as shown in the
following illustration:
You can monitor the Upper Layer Status from Own Node Data screen (page 59)
in the
PCB Diagnostics
menu.
