3.8.1.1 Output parameter
Define the Measured or calculated parameter that is to be output on the specific analogue
output.
3.8.1.2 Output range
The analogue output can be configured to one of six hardware output ranges within which
the analogue output will operate. To ensure the highest accuracy for the output, the range
selected should be the lowest that covers the required analogue output range.
DC current output DC voltage output
0…1 mA 0…1 V
0…5 mA
0...10 mA 0…10 V
0...20 mA
3.8.1.3 Output Signal
Defines the actual range and output curve shape of the required analogue signal. Up to 5
break points can be programmed to achieve the required curve.
FIGURE 3-7: ANALOGUE OUTPUT SETTINGS
If the Analogue output signal is modified from the full linear range, the accuracy of the output
may be reduced due to the reduction in the overall output range.
Note: If the ‘Used’ ranges are changed after the analogue settings have been defined, then
the analogue settings will be modified automatically, see section 3.5.2. It may be necessary
to subsequently modify the settings for the analogue outputs.
3.8.1.4 Average interval for analogue output
Defines the time interval over which the measurement used for an analogue output will be
averaged.
