Dwell Time—the length of time that the Switch States variable has spent in the current state.

Device

Temperature—indicates the temperature of the electronics.

Voltage—indicates the power module voltage.

Quality variables below Temperature and Voltage indicate the overall process data quality of the item. Values are Good,

Degraded, Bad, or Manual/Fixed.

Note

Power module warnings generally only apply to the standard and extended life power modules.

An external power sourced 4320 will provide the supply voltage levels from the output of the external power assembly, not the

voltage of the supply source.

Warning Voltage—the threshold for the power module low-voltage warning.

Critical Voltage—the threshold for the power module critical-voltage warning. Device configuration changes are

prohibited below this voltage.

Run Time Extremes—includes Highest Temperature, Date of Highest, Lowest Temperature, and Date of Lowest.

Select Valve Position, Scaled Position, Last Close Stroke, Last Open Stroke, Temperature, Voltage, Lowest

Temperature, Highest Temperature to view dynamic gauge displays.

Note

Last Close Stroke and Last Open Stroke gauges only appear with the on/off control option and not in snap-acting mode.

Communications

Contains Network and Burst information. Follow the Field Communicator prompts to 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.
