extended to 32 characters long. Neither parameter has any impact on the primary variable
readings of the transmitter, it is only for information.
The Date is a user-defined variable that provides a place to save the date of the last revision of
configuration information. It has no impact on the operation of the transmitter or the
HART-based communicator.
The Descriptor variable provides a longer user-defined electronic label to assist with more
specific transmitter identification than is available with tag. The descriptor may be up to 16
characters long and has no impact on the operation of the transmitter or the HART-based
communicator.
The Message variable provides the most specific user-defined means for identifying individual
transmitters in multi-transmitter environments. It allows for 32 characters of information and is
stored with the other configuration data. The message variable has no impact on the operation
of the transmitter or the HART-based communicator.
