In addition, each dynamic variable has one byte of status accessible via holding
register. The dynamic variables include differential pressure, static pressure, process
temperature and flow. Each variable status reading consists of two parts: measurement
quality and limit status. These variable statuses are found in the register map for
register.
Possible responses for measurement quality status
Good- Displays during normal device operation.
Poor Accuracy – Indicates the accuracy of the variable measurement has been
compromised
Manual/Fixed – Indicates the variable reading has been set to fixed, user specified
value and may not represent the actual process. This status is set if a variable reading
is being simulated or if tha Process Temperature is set to use fixed value.
Bad – Indicates the variable has failed. Example: The differential pressure sensor has
failed.
Possible responses for measurement limit status
Not Limited - Displays during normal operation
High Limited – Indicates the current variable reading has gone above the transmitter’s
maximum possible reading and is no longer representatives of the actual measurement.
Low Limited – Indicates the current variable reading has gone below the transmitter’s
minimum possible reading and is no longer representatives of the actual measurement.
Constant – indicates the variable reading is set to fixed value -Example: The variable
has been left in fixed simulation mode.
