Issue
The shadow objects are showing orange "fault" but the values continue to update?
Environment
G3 (Niagara) ENC, R2 UNC
Cause
A shadow object will go into fault (orange) condition when the LonWorks service is reading a value that it cannot properly decode. This "fault" condition is usually related to a SNVT enumeration that is receiving a value out of the standard SNVTs range. This is typically seen with enumerated SNVT types (e.g. SNVT_occupancy, SNVT_lev_disc, etc.).
For example, an application in the controller is programmed to show occupancy as a value of 0 or 100. The user directly connects the object in the application to the nvoOccupancy tag. Valid enumeration values for this SNVT are 0, 1, 2, 3, etc.. When the value of 100 is read the shadow object will go into fault (turn orange) because a value of 100 is out of the enumeration range the SNVT_occupancy understands.
Resolution
Use WorkPlace Tech to evaluate the controller program and correct any object to SNVT links that could receive a value outside of its acceptable values.
