r0774
Shows the analog output value (in V or mA) after filtering and scaling.
Index:
P0774[0]: Analog output 1 (DAC 1).
P0774[1]: Analog output 2 (DAC 2).
P0776
Defines the type of analog output.
Possible settings:
0 Current output 0 to 20 mA (factory setting)
1 Voltage output 0 to 10 V
Note: The analog outputs are designed as current outputs within 0 to 20 mA. Both
analog outputs must be configured as the same type. Both channels are
configured, e.g., as either current outputs with range 0 to 20 mA, or as voltage
outputs with range 0 to 10 V.
P0777 to P0780:
Define the output characteristic in %. The DAC scaling parameters (P0777 to P0781)
are used to set the output characteristics. They are configured according to the
following curve.

Points P1 (x1, y1) and P2 (x2, y2) are freely selectable.
Example:
The factory-set scaling is as follows:
P1: 0.0%=0mAor0Vand
P2: 100.0 % = 20 mA or 10 V.
Index:
P0777[0]: Analog output 1 (DAC 1).
P0777[1]: Analog output 2 (DAC 2).
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).
