Description
Provides additional device status alerts such as "Device
Needs Maintenance."
Enables field devices to self-validate and report on the
quality of the data in the command response (good, poor,
bad, and fixed).
New Long Tag with international (ISO Latin 1) characters
allows consistent implementation of the longer tag names
required by many industry users. The specifications
currently reflect the length of this tag to be 32 characters.
Improved mechanism for master applications to determine
that a field device configuration has been changed. Protects
integrity of plant configuration databases.
Establishes standard commands and status indicators for
devices based on the type of process measurement. Initial
Device Families include Temperature and PID Control.
New Common Practice commands for performing
transducer trim (calibration) operations.
Simple mechanism using Common Practice Commands to
support "HART device within a HART device" functionality.
Potential uses include flow computers and multi-channel
temperature devices.
An updated mechanism to support the movement of large
blocks of data, such as device configuration information,
between masters and field devices.
Simple mechanism to support the sharing of process data
between field devices on the same HART network. Allows a
listening field device to capture process data from another
field device to be used in calculations such as tank gauging,
flow computers or PID control functions.
New Command to support forcing the digital value for any
Device Variable to a specific value to aid in commissioning
and troubleshooting.
New Commands to allow a master application to lock the
"local" front panel of a field device while performing remote
configuration functions.
