P0777 to P0780, Define output characteristic
P0777 to P0780 defines the output characteristic in %. The analog output scaling parameters
(P0777 to P0781) set the output characteristics and they are configured according to the
following curve.
Points P1 (x1, y1) and P2 (x2, y2) are freely selectable.
P0777: Defines x1 of the output characteristics (factory setting = 0.0).
P0778: Defines y1 of the output characteristics (factory setting = 0).
P0779: Defines x2 of the output characteristics (factory setting = 100).
P0780: Defines y1 of the output characteristics (factory setting = 10).

Example:
The factory-set scaling is as follows:
P1: 0.0 % = 0 mA or 0V
P2: 100.0 % = 20 mA or 10V
Index:
P0777[0]: IN000=Analog output 1.
P0777[1]: IN001=Analog output 2.
P0781, Width of deadband for analog outputs
P0781 defines the DAC deadband for the analog outputs.
Setting range: 0 to 20 mA, or 0 to10V
Factory setting: 0
