Configure MQTT Sparkplug™ B Analog Points
With the MQTT Sparkplug B driver, you use MQTT Sparkplug B Analog Points to either retrieve analog data from, or control analog data on, an EoN node or device that publishes that data to the broker.
Instead of manually creating each MQTT Sparkplug B Point individually, you can use the Create Points from Birth Metrics pick action to create the required suite of points on the EoN Node or Sparkplug B Device with which the points are to be associated. This means of point creation automatically associates the points with the EoN Node or Sparkplug B Device from which the pick action was triggered. You can optionally use the feature with a Property Translation Table to specify any configuration properties that Geo SCADA Expert is to set to particular values when it creates the points. For more information, including essential checks to perform before using the pick action, see Create Points from Birth Metrics, and see Configure an MQTT Sparkplug™ B Property Translation Table.
You configure the properties of each analog point using fields on the MQTT Sparkplug B Analog Point Form. The configuration Form contains many fields, organized into tabs. Most of these tabs contain properties that are common to points on many drivers (see Tabs on Point Forms in the Geo SCADA Expert Guide to Advanced Drivers).
The Analog Point tab includes properties that are specific to MQTT Sparkplug B Analog Points.
Use the Analog Point tab to:
- Configure the Common Point Properties
- Configure the Alarm Limits
- Specify any Alarm Limit Profiles
- Configure the Point Scaling
- Specify the Point Formatting (see Define the Appearance of an Analog Point’s Values in the Geo SCADA Expert Guide to Core Point Configuration)
- Define whether an Analog Point can be Overridden
- Define the Criteria for a Significant Change in Value
- Configure the No Change Properties (see Detect whether an Analog Point has Stopped Changing in the Geo SCADA Expert Guide to Core Point Configuration)
- Define an Analog Point’s Trend Settings.
