Communications
Contains Network and Burst information. Follow the Field Communicator prompts access Network, Review Burst
Message, Hardware Triggering, and Review Event Configuration.
Network
Wireless Mode—indicates the current mode; Idle, Disconnected, Searching, Connected, or Operational
Join Mode—gives instructions to the device with regard to joining the WirelessHART network.
Advanced— contains technical information about communications, such as the number of neighbors recognized by the
instrument on the wireless network, the number of Advertisement packets received, and the number of Join Attempts.
Note
Too many Join Attempts will result in the device considering the join failed; review network configuration.
Note
Advanced network diagnostics are only available in AMS Wireless Configurator or AMS Device Manager when talking to the device
over the maintenance port.
Rejoin Network—reconnect to network with existing credentials.
Disconnect—drop off the network. This should only be done if recommissioning or performing a service procedure that
interferes with network operation.
Review Burst Message
Burst shows diagnostics for each burst message.
The message Bandwidth Status shows:
D whether a given message is enabled in the device
D whether it is still waiting for bandwidth allocation from the network for its requested update rate
D whether it has been assigned bandwidth but at a lower rate than requested
D whether it is actively publishing
D whether it is in Delayed Publishing mode (Using Delayed Trigger mechanism).
The configured Message Content, Trigger Mode, and active Update Rate are displayed next.
If the message is enabled, you can view a snapshot of the values that would be published in the message, based on the
current device states.
Hardware Triggering
Details associated with the device hardware circuit that checks for position sensor input changes while the firmware is
asleep, and issues a wake­up call if a change occurs. An estimate of the sensitivity and a count of the number of times
the circuit has tripped since the counter was last cleared is provided; this may be used to help balance triggering
response, battery life, and traffic on the wireless network.
