Safety messages
WARNING
The products described in this document are NOT designed for nuclearqualified applications.
Using non-nuclear qualified products in applications that require nuclearqualified hardware or products may cause inaccurate readings.
For information on Rosemount nuclear-qualified products, contact your
local Emerson Sales Representative.
Follow instructions
Failure to follow these installation guidelines could result in death or serious
injury.
Ensure only qualified personnel perform the installation.
Physical access
Unauthorized personnel may potentially cause significant damage to and/or
misconfiguration of end users’ equipment. This could be intentional or
unintentional and needs to be protected against.
Physical security is an important part of any security program and
fundamental to protecting your system. Restrict physical access by
unauthorized personnel to protect end users’ assets. This is true for all
systems used within the facility.

WARNING
Explosions
Explosions could result in death or serious injury.
Installation of the transmitters in a hazardous environment must be in
accordance with the appropriate local, national, and international
standards, codes, and practices. Please review the Product Certifications
section for any restrictions associated with a safe installation.
Do not remove the connection head cover in explosive atmospheres
when the circuit is live.
Before connecting a handheld communicator in an explosive
atmosphere, ensure the instruments are installed in accordance with
intrinsically safe or non-incendive field wiring practices.Verify the
operating atmosphere of the transmitter is consistent with the
appropriate hazardous locations certifications.
All connection head covers must be fully engaged to meet explosionproof requirements.
Process leaks
Process leaks could result in death or serious injury.
Do not remove the thermowell while in operation.
Install and tighten thermowells and sensors before applying pressure.
Electrical shock
Electrical shock could cause death or serious injury.
Avoid contact with the leads and terminals. High voltage that may be
present on leads can cause electrical shock.
CAUTION
Conduit/cable entries
Unless otherwise marked, the conduit/cable entries in the housing
enclosure use a ½–14 NPT form. Only use plugs, adapters, glands, or
conduit with a compatible thread form when closing these entries.
Entries marked "M20" are M20 x 1.5 thread form.
When installing in a hazardous location, use only appropriately listed or
Ex certified plugs, glands, or adapters in cable/conduit entries.

3Wire and apply power
Wiring diagrams are located inside the terminal block cover.
An external power supply is required to power a Fieldbus segment.
The power required across the transmitter power terminals is 9 to 32 Vdc
(the power terminals are rated to 32 Vdc). To prevent damaging the
transmitter, do not allow terminal voltage to drop below 9 Vdc when
changing the configuration parameters.
3.1Power filter
A Fieldbus segment requires a power conditioner to isolate the power supply
filter and decouple the segment from other segments attached to the same
power supply.
3.2Power the transmitter
Procedure
1. Remove the terminal block cover (if applicable).
2. Connect the power lead to the power terminals.
The Rosemount with FOUNDATION Fieldbus is polarity insensitive.
If a transient protector is being used, the power leads will now be
connected to the top of the transient protector unit.
3. Tighten the terminal screws.
When tightening the sensor and power wires, the max torque is 6 in-
lb (0.7 N-m).
4. Reattach and tighten the cover (if applicable).

To identify which device is at a particular location use the removable tag
provided with the transmitter. Ensure the physical device tag (PD Tag field)
is properly entered in both places on the removable commissioning tag and
tear off the bottom portion for each transmitter.
Note
The device description loaded in the host system must be at the same
revision as this device. You can download the device description from
Emerson.com/Rosemount.
Quick Start Guide15
Quick Start GuideApril 2020
6Transmitter configuration
Each PROFIBUS capable host or configuration tool has a different way of
displaying and performing configurations. Some use Device Descriptions
(DD) or DD methods for configuration and to display data consistently
across platforms. There is no requirement that a host or configuration tool
support these features.
The following is the minimum configuration requirement for a temperature
measurement. This guide is designed for systems not using DD methods. For
a complete list of parameters and configuration information refer to the
Rosemount 644 Head and Rail Mount Temperature Transmitter Reference
Manual.
The Rosemount 644 must be configured via a Class 2 master (DD or DTM
based). The basic configuration tasks for the PROFIBUS PA Temperature
Transmitter include:
• Assign address.
• Set sensor type and connection.
• Configure engineering units.
6.1Assign address
Rosemount ships the transmitter with a temporary address of 126. To
establish communication with the host, change the address to a unique
value between 0 and 125. Usually, addresses 0-2 are reserved for masters or
couplers; therefore Emerson recommends using transmitter addresses
between 3 and 125.
Note
When shipped from the factory, Rosemount 644 PROFIBUS Profile 3.02
devices are defaulted in Identification Number ADAPTATION MODE. This
mode allows the transmitter to communicate with any PROFIBUS control
host with either the generic Profile GSD file (9700) or the Rosemount 644
specific GSD (4153) loaded in the host; therefore, you do not have to change
the transmitter identification number at startup.
6.1.1Transducer function block
This block contains temperature measurement data for the sensors and the
terminal temperature. It also includes information about sensor types,
engineering units, damping, and diagnostics.
SPECIAL_SENSOR_AEnter sensor specific coefficients
SPECIAL_SENSOR_BEnter sensor specific coefficients
SPECIAL_SENSOR_CEnter sensor specific coefficients
SPECIAL_SENSOR_R0Enter sensor specific coefficients
6.1.2Analog Input (AI) function block
The AI block processes field device measurements and makes the outputs
available to other function blocks. The output value of the AI block is in
engineering units and contains a status indicating the quality of the
measurements. Use the channel number to define the variable that the AI
block processes.
At a minimum, verify the parameters of each AI block in Table 6-2.
Table 6-2: AI Block Parameters
Configure one AI Block for each desired measurement.
ParameterComments
CHANNELChoices:
1. Sensor 1
2. Housing Temperature
LIN_TYPEThis parameter defines the relationship between the block

input and the block output. Since the transmitter does not
require linearization, this parameter will always be set to No
Linearization. This means that the AI block will only apply
scaling, filtering, and limit checking to the input value.

Note
To make changes to the AI block, set the BLOCK_MODE (TARGET) to OOS

6.2
Physical block
The Physical Block encompasses all parameters and functions required to
identify the hardware and software (revision numbers, status values, device
address etc.) of the device. Use the IDENT_NUMBER_SELECTOR parameter
to change how the host sees the device.

IDENT_NUMBER_SELECTORCan be changed to Profile Specific,
Manufacturer Specific, or Adaptation
mode.
• Adaptation mode (default): The Host
chooses which file (GSD) it wants to
use and whether to view the device
GSD file in a generic or a
manufacturer specific way.
• Profile Specific mode: Shows the
generic GSD associated with the
PROFIBUS Profile version (9700) of
the device.
• Manufacturer Specific mode:
Displays the GSD file with
parameters specific to the
transmitter.
6.3Host integration
Control host (Class 1)
The Rosemount 644 device utilizes Condensed Status as recommended by
the Profile 3.02 specification and NE 107. See manual for Condensed Status
bit assignment information.
The appropriate GSD file must be loaded on the control host - Rosemount
644 specific (rmt4053.gsd) or Profile 3.02 Generic (pa139700.gsd). These
files can be found on Emerson.com/Rosemount or www.profibus.com.
Configuration host (Class 2)
The appropriate DD or DTM file must be installed in the configuration host.
These files can be found at Emerson.com/Rosemount.
