2. In a second step, the interval [0,1] is mapped to the interval [OUT_SCALE_MIN,
OUT_SCALE_MAX]. The value resulting from this mapping is transfered via V6H2 to the PLC.
!
Note!
The scaling of the ouptut value is required by the Profibus profiles. It prevents uncontrolled jumps
of the output value when one changes the unit of the measuring value in the Transducer Block. If
units are changed, PV_SCALE_MIN and PV_SCALE_MAX automatically adapt themselves in such
a way that the output value remains unchanged. Only after confirming the change by the "
Set unit
to bus " (062) function,
OUT_SCALE_MIN is set equal to PV_SCALE_MIN and
OUT_SCALE_MAX equal to PV_SCALE_MAX.
Thereby the new unit also becomes effective at the output.
"
Caution!
If a linearisation has been carried out, it must be confirmed by the "
Set unit to bus " (062) function
in order to become effective at the digital output.
