Virtual Data Points (formerly NVVs)
Interoperable Self-Installation (ISI) data points and data points containing connection manager and
LonTalk statistics are located under the <network>/VirtCh/iLON System (Internal)/VirtFB object
and are named accordingly. For example, the ServicePinMessage data point is named
“Net/VirtCh/iLON System/VirtFb/ServicePinMessage”.
Constant Data Points (formerly NVCs)
Constant data points are located under a <network>/LON/iLON App (Internal)/<functional block>
object and are named “CompareDP”. The functional block represents the SmartServer embedded
application in which the constant data point is used. For example, a constant data point used in an
Alarm Generator could be named “Net/LON/iLON App/Alarm Generator[0]/CompareDP”.
