Setting Parameters for Scaling
Value x1 for the analog input
p4057[0]
characteristic
Setting for the x coordinate in V or mA of the first point on the scaling characteristic.
The unit is V when analog input 0 is set as a voltage input (p4056 = 0 / 4) and switch S5.0 is set to "V".
The unit is mA when analog input 0 is set as a current input (p4056 = 2 / 3 / 5) and switch S5.0 is
set to "I".
Value y1 for the analog input
p4058[0]
characteristic
Setting for the y coordinate in % of the first point on the scaling characteristic.
