Specifications and Reference Data
A.5 Configuration
A.5.1 Transmitter configuration
The transmitter is available with standard configuration settings
for HART. The configuration settings may be changed in the field
with DeltaV
™
, with AMS Device Manager, or with any field
communicator.
A.5.2 Standard HART Configuration
Unless specified, the transmitter will be shipped as follows:
A.5.3 Tagging
Hardware tag
13 characters total
Tags are located on adhesive labels permanently affixed to the
transmitter
Software tag
HART Revision 5
A HART Revision 5 transmitter can store up to eight characters for
the HART software tag and defaults to the first eight characters of
the hardware tag.
HART Revision 7
A HART Revision 7 transmitter can store the same eight character
tag as the Revision 5 but has a additional and separate Long
software tag that can be configured for up to 32 characters.
A.5.4 Considerations
Special mounting considerations
See
for the special hardware that is available
to:
Mount a Rosemount 644H to a DIN rail. (see
)
Retrofit a new Rosemount 644H to replace an existing
Rosemount 644H Transmitter in an existing threaded sensor
connection head. (see
External ground screw assembly
The external ground screw assembly can be ordered by specifying
code G1 when an enclosure is specified. However, some approvals
include the ground screw assembly in the transmitter shipment,
hence it is not necessary to order code G1. The table below
identifies which approval options include the external ground
screw assembly and which do not.
