Figure 42 shows the default actions available on a SedonaJen6lpDevice.
Device actions include the following:
Ping
Verifies join status with the coordinator (SedonaJen6lpNetwork).
Load Pan Info
Forces a load of the device’s JenNet PAN info into its Parent Pan Info and Child Pan Info properties.
Delete Pan Info
Deletes all JenNet PAN info from the device’s Parent Pan Info and Child Pan Info properties.
Delete Stale Pan Info
Deletes all JenNet PAN info entries currently marked “stale” (property Stale = true). These entries may exist after the tree structure of the Jennic wireless network changes.
Request Maintenance Mode
Applies only to hibernating devices (say battery-powered)—to provide the ability to make a Sox connection to it from Workbench. For more details, see About maintenance mode.
If a non-hibernating device, this action has no purpose and may be safely hidden. As currently Sedona Framework support for
hibernating devices is not widely distributed, this is yet another reason to hide this action.
Maintenance mode is a routine that applies to hibernating devices only. At the time of this document, Sedona Framework support
for hibernating devices is not widely available. However, NiagaraAX support for such devices, including “Maintenance Mode”
operation, is included in the SedonaJen6lpNetwork driver.
Most hibernating devices, typically battery-powered devices, remain in a low-power or “hibernating” state. During this state, the Sedona VM and RF communications are disabled to conserve battery life. Consequentially, Workbench cannot make a Sox connection to the device.
In order to allow a Sox connection from Workbench to a device that hibernates, its Sedona Framework app is configured with a “ChopanNetwork” client that periodically queries the coordinator (JACE) to see if it should enter a maintenance mode.
This request is typically done using the “Request Maintenance Mode” action on the SedonaJen6lpDevice that represents the hibernating device. Once invoked, upon the next “maintenance mode check” message from the device (as part of its Chopan setup), the device sees that flag set, and then suspends hibernation for a “maintenance mode timeout” period.
At that time, in Workbench a modal “Maintenance mode active” popup appears, with the Niagara name of the associated SedonaJen6lpDevice component. See Figure 43 for an example popup.
The popup signals the start of the “maintenance mode active time”. During this period, before the timeout, you can use Workbench to open a Sox connection to that device (typically a Sox tunnel connection). If a Workbench Sox connection is not made in that time period, the device returns to hibernating, that is, resumes its normal operation.
Three related properties of a SedonaJen6lpDevice indicate maintenance mode states and the (Sedona configured) maintenance mode timeout duration. See SedonaJen6lpDevice properties.
