Analog output zero scale and full scale values
Configure your analog output’s zero and full scale values.
In most cases your meter’s analog output range matches the range of the analog
sensors that your meter’s outputs are connected to. In that case, your meter’s analog
output zero scale and full scale values are the maximum and minimum values of the
source driving your meter’s analog output. These values are used to normalize the
source value to a value between 0 and 1 which is applied to the operating range of the
analog output port to determine the analog output current or voltage. For example:
Source value
Analog output values
Meter’s analog output
Analog sensor
0 to 120 kW range
100 kW
Full scale = 120 (kW)
Zero scale = 0 (kW)
Normalized: 0.83
4 - 20 mA range
Output: 17.28 mA
4 - 20 mA range
If your meter’s analog output range does not match the range of the connected analog
sensor, you must calculate the full scale and zero scale values by analyzing the
system.
See the ION Reference, available from www.usa.siemens.com/pds for detailed
information about the Analog Output module and full scale and zero scale calculations.
Configuring option module analog outputs using ION Setup
You can configure option module analog outputs using ION Setup.
Analog outputs are available on the optional I/O modules you can connect to the base
of your meter.
Calculate your zero scale and full scale values based on the measured value and the
analog output range of your meter.
Make sure that the analog output port that you want to use is properly connected to an
analog receiver.
1. Start ION Setup.
2. Open the Setup Assistant for your meter.
3. Navigate to
Expansion Module > Option I/O Modules
and select the module tab
that corresponds to the option module with the analog output you want to configure.
4. Select the analog output channel and click
Edit
. The setup screen for that analog
output is displayed.
5. Configure the analog output by selecting the parameter and clicking
Edit
.
