Performing basic parameterization
6.1 Control Unit
2. Select the signal sources (p0771[0...2]) whose signal is to be output via the measuring
socket for the respective measuring sockets T0, T1 and T2.
3. The scaling specifies the processing of the measured signal. This requires the definition
of a straight line with two points.
Click the "Scaling" button in the adjustment range of a measuring socket.
The "Scaling CU320 measuring socket Tx" dialog opens. You can define the values of a
characteristic curve in this dialog.
4. In the dialog, select individual values within their defined limits, which are displayed in the
relevant tooltips.
– Characteristic value x2 (p0779)
– Characteristic value y2 (p0780)
– Characteristic value y1 (p0778)
– Characteristic value x1 (p0777)
Example: x1/y1 = 0%/2.49 V x2/y2 = 100%/4.98 V
– 0.0% is mapped to 2.49 V.
– 100.0% is mapped to 4.98 V.
– -100.0% is mapped to 0.00 V.
5. Confirm your entries with "OK".
6. Enter the required offset value in the "Offset" field for the relevant measuring socket.
The offset is applied additively to the signal to be output. The signal to be output can thus
be displayed within the measuring range.
