The following information provides a field description of the Data Point and Settings tab in Unit Admin. Fields include those for setting up analog, digital, active digital, and accumulator data points when working with any unit type in the APM4AM family. APM4AM unit types include the APM4AM-GSM, APM4AM-GSM2, APM4AM-SAT, and APM4AM-ORB.
Note: No fields are available for data entry on the Settings tab when working with digital and active digital channels.
To display the Data Point or Settings tab in Unit Admin:
- Click All Units in Unit System Status.
- Click a unit in the Unit column of All Units View.
- Click Settings or the pencil icon to display Unit Admin.
- Click a data point in the navigation pane.
The Data Point tab displays by default after clicking a data point. Click the Settings tab to display fields available for data entry.
The Data Point tab includes the following fields. ˆtop of pageˆ
- Alias: A user-friendly name for a data point. Enter a description that is meaningful to your company, such as a unique part number or other type of identifier.
- Data Point Name: System-generated name for a data point. This field is not editable.
- Display As: Analog only. Identifies the output of a data point. Options are: As Is (Value as Decoded), Value Converted °C to °F, Value Converted °F to °C, or Descriptions for Values.
- Decimal Places: Analog and Accumulator only. Identifies how many numbers appear after the decimal in a measurement reading.
- Offset: Analog only. A decimal number added to the Data Point display value; shown in engineering units. Default is 0.
- Engineering Unit Label: Identifies the unit of measurement for the option selected in the 'Display As' field. For example, if 'Display As' is Volts, type V, VAC, VDC, volts, or a similar description.
- Value Descriptions: Analog only. Displays code values and their description. Use the Add Description fields to add a code value and its description.
- State Conversions: Digital and Active Digital only. Description and icon associated with a contact closure state. Enter a description in the Conversion field and then choose and icon from the list to associate with a contact closure state in the Value field.
- Correction Factor: Accumulator only. Optional field for identifying the accumulator correction factor. The manufacturer of the accumulator determines which correction factor you may need to provide.
The Settings tab includes the following fields. ˆtop of pageˆ
In the Settings tab, Live Scaling displays the data point's current processed value (Current Value) along with a re-processed value (Modified Scale Value) showing what the current value would have been if the current scaling was used. The re-processed value is updated as the you change scaling values.
Analog only:
- Voltage Card: Select the voltage output of the input device. Options are ±5V or ±50mV.
- Raw Input High: The high (maximum) raw voltage output value of the input device. This value should match the value that was used when the unit was configured in the field using the Universal Configuration Toolkit.
- Raw Input Low: The low (minimum) raw voltage output value of the input device. This value should match the value that was used when the unit was configured in the field using the Universal Configuration Toolkit.
- Engineering Unit: Defines the unit of measurement, such as volts or amps.
- Engineering Unit Maximum: Defines the sensor's maximum rating. This value should match the value that was used when the unit was configured in the field using the Universal Configuration Toolkit.
- Engineering Unit Minimum: Defines the sensor's minimum rating. This value should match the value that was used when the unit was configured in the field using the Universal Configuration Toolkit.
Accumulator only:
- Calculated Use Date: This field is used in reports as a base date for calculating the difference in measurement readings.
