The Upper Layer Status word is structured as follows:
Upper Layer Status Word
Bit Description Value
0 to 11 Error Code (User Defined) 0x0001
12 reserved 0x1000
13 1=Warning, 0=No Warning 0x2000
14 1=Alarm, 0=No Alarm 0x4000
15 1=Run, 0=Stop 0x8000
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
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 the Display Own Node Status
command in the Configuration/Debug menu.
