Configure MQTT JSON Schema A Analog Points
With the MQTT JSON Schema A driver, you use:
- MQTT JSON Schema A Analog Points to retrieve analog data from a device that publishes that data to the broker. The data has to be associated with an MQTT topic to which Geo SCADA Expert has subscribed.
You configure the properties of each analog point using fields on the MQTT JSON Schema A 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 JSON Schema A Analog Points.
Use the Analog Point tab to:
- Configure the Common Point Properties
- Configure the Alarm Limits
- Configure any Alarm Limit Profiles (see Specify any Alarm Limit Profiles in the Geo SCADA Expert Guide to Core Point Configuration)
- 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)
- Specify the Override Properties (see Define whether an Analog Point can be Overridden in the Geo SCADA Expert Guide to Core Point Configuration)
- Configure the No Change Properties (see Detect whether an Analog Point has Stopped Changing in the Geo SCADA Expert Guide to Core Point Configuration)
- Specify the Trend Properties (see Define an Analog Point’s Trend Settings in the Geo SCADA Expert Guide to Core Point Configuration)
- Configure the Logged Data Properties (see Specify the Type of Point Data that the Driver is to Store Historically).
