The “Source Sensor Assignment” column shows which sensor/measurement type should be assigned to this OID (in which
format/unit), and where appropriate which conversion/scaling should be configured in the LCom sensor configuration, before the
measurement is processed in the NTCIP section of the LCom. A scaling is stored in the NTCIP sensor configuration for each OID
(independent of any possible scaling/value mapping in the LCom sensor configuration), which usually converts the unit delivered by
the UMB sensor channel (e.g. °C) to the encoding required by the NTCIP standard (e.g. 1/10°C).
For measurement values which require “value mapping” (e.g. road condition), a default value mapping is used (e.g. “Road Condition
Lufft (def) to NTCIP”) if no other value mapping is set for the corresponding sensor in the LCom sensor configuration. The default
value mappings can be freely configured and changed
– as can all other value mappings – or a different value mapping can be used
by configuring a value mapping for the respective UMB sensor channel in the LCom sensor configuration.
Note for “Precipitation Intensity”:
some of the OIDs expect a “source sensor” (see “Source Sensor Assignment” column below)
scaled as “1/10 mm/h”. This is provided “native” by the UMB sensor channel for precipitation intensity. If you use other UMB sensor
channels here, you might need to either scale the UMB sensor value to 1/10 mm/h, or adjust the scale factor for the respective OID.
