Starting in Sedona TXS-1.2, any Sedona device (SedonaDevice or SedonaJen6lpDevice) has a SedonaDeviceInfoExt (Device Info extension). This device extension contains read-only properties about the device’s Sedona platform type.
As shown in Figure 22, you can access this device extension from the Workbench Nav tree, Sedona Device manager, or from the property sheet of the Sedona device.
Any method shown above:
double-click Device Info in the Nave tree, or
click on a Ext in the Device Manager, or
click on Device Info in a property sheet
produces the property sheet for the SedonaDeviceInfoExt. See Figure 23.
Properties are read-only status types, read upon station startup (and also whenever a device transitions online from either “down” or “disabled”), and include the following:
Platform Id
The unique platform ID, a property in the Sedona “plat” component in the device’s app. The value of this string begins with “vendor-
”, and typically includes platform version information too.
Platform Version
Another property of the Sedona app’s “plat” component, reflecting the platform version number.
App Name
The string value of the App Name property in the device’s top-level “App” component.
Device Name
Another property of the Sedona App component (may or may not be implemented in the device).
In addition to the properties above, Device Info also contains a child slot:
Refresh Task
This container has two properties: Status and Fault Cause. It functions to query the Sedona device to refresh the property values (above) in the parent Device Info extension, via right-click actions.
A refresh may be necessary if a Sedona device has been provisioned (or re-provisioned) since the last station startup. In case a normal attempt to read device info properties fails (upon station startup, or device status transition from “down” or “disabled”), a refresh is automatically rescheduled.
The Sedona Device Info Ext has an available Refresh action, which is equivalent to the Execute action of its child Refresh Task component.
Currently, Device Info property values are not available in any manager view (such as the Sedona Device Manager), but are available for any one selected device using methods shown in Figure 22.
