Display WIOC device network data

To display the WIOC Device Network Data dialog, listing the update rate and commissioned status of an active or decommissioned WIOC device, complete the following steps:

Right-click the active or decommissioned wireless I/O card (WIOC) device for which you want to see network data.
Click Display Network Data to open the WIOC Device Network Data dialog.

The following table describes possible values:

Network Data Name	Value
Active Neighbors	The names of the other devices that have dedicated communications links to this device. Note The device may see other neighbors, but they do not have dedicated communications links scheduled by the network manager.
Burst Rate	The time interval in seconds that the device takes measurements and publishes them over the wireless network. Note If a HART device does not support this feature, the Burst Rate statistics value appears as 0 in DeltaV Diagnostics.
Discarded Updates	Total number of published updates by the device that have been received out of order (after a more recent update). Note This happens when there are fast update rates and poor link/path stabilities.
Join Time	The date and time that the device last joined the network.
Joins	The number of times the device has joined the network.
Last Update	The date and time that the device last received an update.
Latency	The number of seconds between when a value is sent by the device and when it is received by the WIOC.
Missed Updates	Total number of published updates by the device that have not been received by the WIOC or are received too late.
Needs Neighbor	True when the device needs one or more neighbor devices to support the update rate it has requested. The network manager also requires a minimum of two neighbors. Note Poor link/path stability between devices can cause the network manager to set the Needs Neighbor value to True.
Network Durability	The communications strength with the WIOC, expressed as a percentage. This value is based on updates that are actually broadcast (not including lost updates when a device loses power), is calculated over a 15 minute window, and counts only if the update eventually gets to the WIOC eventually. Discarded updates are included in the calculation. Note The Reliability value is a better indicator of communications strength.
Node State	The current state of the node: Live, Stale, Unreachable, or Service Denied.
Path Stability	The communications strength between the device and its neighbor, expressed as a percentage. The value reported is only the best link/path stability, although this value exists for each neighbor. Calculation of the Path Stability value is similar to that used for the Network Durabilty value.
Reliability	The communications strength with the WIOC, expressed as a value from 0 to 1.00. Note The Reliability value is calculated outside of the network manager and is more meaningful than the Network Reliability value reported by the network manager.
RSSI	The decibel value of a Received Signal Strength Indication (RSSI) measurement between the device and the neighbor with which the strongest signal is recorded.
Service Currently Denied	True when the network manager does not grant wireless publishing services to the device. The device is still on the network, will respond to polled commands, and pass traffic for other devices on the network. Note This typically happens when the device is configured for an update that is too fast (not supported) for the WIOC or if the network manager has reached its limit for incoming published messages.
Total Missed Updates	Total number of published updates by the device that have not been received by the WIOC or are received too late.
Updates	Total number of published updates by the device that have been received by the WIOC.
