If you choose not to use the "simple" mode, you must enter the 4 values to calculate
the scaling by applying the equation of a line given that you know two points. Then
the value of X0 and X1 corresponds to the value read in the analog/digital converter
of the device (0 for 0V, 4000 for 10V, or 800 for 4 mA and 4000 for 20 mA). The
value of Y0 and Y1 will be the output value for these two input points.
Returning to the initial example the values to be configured would be X0 = 800, Y0 =
-100,
X1 = 4000 and Y1 = 500.
The limit values for Y are -32767 to 32767.
The scaled value can be displayed on the monitoring page, in a Modbus record and in CSV and
XML format.
