4.2.2.10 Using the PV simulation mode
For diagnostics purpose of the connected process control system, it is
possible to simulate an arbitrary measurement value without moving the
float physically. Hereby, external switching functions and cabling can be
tested.
Access:
Setup -> 4-20 mA -> PrimVar -> Simulation
Possible values:
-
100 … (SL+100) mm
4.2.2.11 Mapping of the analogue output to a measurement channel
It is possible to use any measurement channel of the sensor for control of
the analogue output.
This channel is designated “PV” (Primary Value). By
means of the HART® protocol, all channels can be read out at any time.
Access: Setup -> HART -> PrimVar -> Mapping
Possible settings are:
