STEP 2: WIRE AND APPLY POWER
• Wiring diagrams are located inside the terminal block cover and on the transmitter top
label.
• An external power supply is required to power a Profibus 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.
Power Filter
A Profibus segment requires a power conditioner to isolate the power supply filter and
decouple the segment from other segments attached to the same power supply.
Power the Transmitter
1. Remove the terminal block cover (if applicable).
2. Connect the power lead to the power terminals (The 644 power terminals are polarity
insensitive for the Profibus protocol.)
3. Tighten the terminal screws. When tightening the sensor and power wires, the max
torque is 6 in.-lbs. (0.7 N-m).
4. Reattach and tighten the cover (if applicable).
5. Apply power (9 – 32 VDC).
Sensor Connections Diagram
* The transmitters must be configured for at least a 3-wire RTD in order to recognize an RTD with a
compensation loop.
** Emerson Process Management provides 4-wire sensors for all single element RTDs. Use these
RTDs in 3-wire configurations by leaving the unneeded leads disconnected and insulated with electrical
tape.

Typical Configuration for Profibus Networking
NOTE
1. Each segment in a Profibus trunk must be terminated at both ends.
2. Some DP/PA couplers contain the power supply, one terminator, and the power
conditioner within the coupling device.
3. The configuration tool is typically located in the control room.
Ground the Transmitter
Ungrounded Thermocouple, mV, and RTD/Ohm Inputs
Each process installation has different requirements for grounding. Use the grounding
options recommended by the facility for the specific sensor type, or begin with grounding
Option 1 (the most common).
Option 1:
1. Connect sensor wiring shield to the transmitter housing.
2. Ensure the sensor shield is electrically isolated from surrounding fixtures that may be
grounded.
3. Ground signal wiring shield at the power supply end.

STEP 3: VERIFY TAGGING
STEP 4: TRANSMITTER 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 (document number 00809-0100-4728).
The 644 must be configured via a Class 2 master (DD or DTM based). The basic
configuration tasks for the Profibus PA Temperature Transmitter include:
1. Assign Address
2. Set Sensor Type and Connection
3. Configure Engineering Units
Assign Address
The Rosemount 644 Pressure Transmitter is shipped with a temporary address of 126. This
must be changed to a unique value between 0 and 125 in order to establish communication
with the host. Usually, addresses 0-2 are reserved for masters or couplers, therefore
transmitter addresses between 3 and 125 are recommended.
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, if is not required to
change the transmitter identification number at startup.
Commissioning (Paper) Tag
To identify which device is at a particular location use
the removable tag provided with the transmitter.
Ensure that 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. The
device description can be downloaded from
www.rosemount.com.

Transducer Function Block
This block contains temperature measurement data for the sensor and the terminal
temperature. It also includes information about sensor types, engineering units and
diagnostics. At a minimum, verify the parameters in Table 1.
Table 1. Transducer Block Parameters
Analog 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 2.

Table 2. AI Block Parameters
Parameter Comments
CHANNEL The CHANNEL parameter defines which transducer
block measurement is used by the AI block. In the 644
Transmitter, the channel will always be set to Sensor 1.
There is no other option for this variable.
LIN_TYPE This parameter defines the relationship between the
block input and the block output. Since the 644
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.
PV_SCALE Set desired measurement range and units. Units must
be one of the following:
•mV
•Ohms
•°C
•°F
•°R
•K
OUT_SCALE For “DIRECT”, set OUT_SCALE to match PV_SCALE
HI_HI_LIM
HI_LIM
LO_LIM
