Description
No rescaling of the Modbus UDR
value. Scaling arguments are
ignored.
Linear scaling of the source
value between the source range
"Min In"..."Max In" into UDR
value range "Min Out"..."Max
Out". The scaled UDR value
saturates at "Min Out" and "Max
Out" values.
The source value is multiplied
with scaling argument 1 (similar
to argument in Ratio "Min In").
Other scaling arguments are
ignored.
The source value is divided by
the scaling argument 1 (similar to
argument in Ratio "Min In").
Other scaling arguments are
ignored.
Scaling argument 1. Used also
as the scaling factor for
Multiplicative and Divisor
scaling.
Scaling argument 2.
Scaling argument 3.
Scaling argument 4.
32-bit register value expressed
according to "de facto" standard.
Word order High-Low.
32-bit register value word order
changed to Low-High.
16-bit register value expressed
according to Modbus standard.
Byte order High-Low.
16-bit register value byte order
changed to Low-High.
