Parameter: Range active
•
Default setting (_:107) Range active = false
If you do not activate the Range active parameter, the function assumes a range of -20 mA to +20 mA or
-10 V to +10 V. The setting of the range for the scaled value then assumes a usable range of -20 mA to +20
mA or -10 V to +10 V.
If you activate theRange active parameter, then 4 additional parametersUpper limit, Upper limit
- SensorLower limit, and Lower limit - Sensor appear.
Note that this setting is activated by either placing, or not placing the relevant check mark in DIGSI (see
Figure 6-52).
Parameter: Conversion factor
•
Default setting (_:104) Conversion factor = 1.00
With the parameterConversion factor you can set the conversion factor for the measuring transducer.
Parameter: Upper limit, Upper limit - Sensor, Lower limit and Lower limit - Sensor
With the following parameters, you set the scaling of the measuring variables. By that, you can scale in an
application-specific way:
•
Default setting Upper limit = 20.00 mA
•
Default setting Upper limit - Sensor = 1.00
•
Default setting Lower limit = -20.00 mA
•
Default setting Lower limit - Sensor = 1.00
With these setting parameters, you set the operating range of the measuring transducer as well as the conver-
sion of the values transmitted to the sensor values. Harmonize the operating range of the measuring trans-
ducer with the transmitter of the sensor. Using the free scalability of the system, you can meet different
requirements. The following figure shows the setting parameters in general terms.
