1. Introduction
1.1 About the ST 700 FF Pressure Transmitter
The newly designed Honeywell ST 700 is a smart pressure transmitter that has a wide
range of additional features along with supporting the FOUNDATIONTM Fieldbus (FF)
communication protocol. The ST 700 pressure transmitter with FF protocol provides a
FOUNDATIONTM Fieldbus interface to operate in a compatible distributed Fieldbus
system. The transmitter includes FOUNDATIONTM Fieldbus electronics for operating in a
31.25 Kbit/s Fieldbus network and can interoperate with any FOUNDATIONTM Fieldbus
registered device.
The STD700 is a high performance pressure transmitter featuring Piezo-resistive sensor
technology. By combining differential pressure sensing with on-chip static and temperature
compensation, the STD700 offers high accuracy and stability over a wide range of
application pressures and temperatures. The STG700 and STA700 are high performance
pressure transmitters featuring Piezo-resistive sensor technology combining pressure
sensing with on-chip temperature compensation capabilities providing high accuracy,
stability and performance over a wide range of application pressures and temperatures.
The SmartLine family is also fully tested and compliant with Experion ® PKS providing
the highest level of compatibility assurance and integration capabilities. The ST 700 easily
meets the most demanding application needs for pressure measurement applications. This
transmitter is used in the process automation industry for sensing and transmitting pressure
over intelligent communication networks.
The transmitter comes in a variety of models for measurement applications involving one
of these basic types of pressure:
•Differential Pressure (DP)
•Gauge Pressure (GP)
•Absolute Pressure (AP)

2. Getting started
2.1 Verifying the installation
Verifying transmitter installation tasks
After the transmitter is installed and powered up, you can verify communication between
the transmitter and the field devices on the network. Table 1 outlines the steps for
identifying and checking the transmitter on a Fieldbus network.
Table 1: Transmitter installation verification tasks
Task Description Comment
Verify device location Check that the device is installed in the
correct physical location.
Verify device ID Match the device ID with the physical
location.
The device serial number is the PROM ID
which is stamped on the transmitter
housing nameplate.
Verify connection with
host computer to
device
On the operator interface, check and
make sure communications are
established with the device on the
Fieldbus network.
Verify or assign Device
Tag and address Check that the Device Tag and node address are set. If not, assign the Device
Tag and the correct node address.
The Device Tag and address can be set
and viewed using the Fieldbus device
configurator application. Use a Device Tag
name (up to 16 characters) that does not
contain spaces.
Configure device Using a Fieldbus configuration program,
create a function block application as part
of the device configuration and process
control strategy.
Verify device operation Bring the network online, verify operation,
tune loops, and so on.

Page 6 FOUNDATION Fieldbus ST 700 Pressure Transmitter User's Guide Revision 2.0
2.2 Verifying communication with the transmitter
On the operator interface, establish communication with the device on the Fieldbus network.
If the device is not visible on the network, verify that the device has been installed properly.
Identify the transmitter
Verify the Device ID of the transmitter by checking the device parameters. The parameters
contain the following information:
•Transmitter type (pressure transmitter, temperature transmitter, and flow transmitter)
•Device Tag (tag description of the transmitter)
•Sensor serial number
•Firmware revision level (revision level of the firmware elements)
Check the transmitter parameters listed in Table 2 and note down the values to identify the
transmitter.
ATTENTION
It is recommended to verify the correct version of the Device Description file is
present on the host computer. (Refer to the document on the diskette shipped
with the transmitter.) This helps in getting the correct parameter names and its
corresponding descriptions, while viewing the device parameters.
Table 2: Transmitter parameters
Parameter To verify
Resource block
DEV_TYPE
That the transmitter is of the proper
device type.
For all the ST 700 type pressure
transmitters, the value is 0003.
Device Tag
(Physical device tag name of the transmitter)
The Device Tag is correct.
Device Tag name __________________
ATTENTION
The Device Tag name can be set and viewed
using the Fieldbus device configurator application.
Use a device tag name (up to sixteent characters)
that does not contain spaces.
Transducer Block
SENSOR_SN
Sensor serial # ________________
The SENSOR_SN value, when viewed
as a hexadecimal number, is the same
number as the first sixteen digits of the
PROM ID stamped on the transmitter
housing nameplate.
ATTENTION
Note that the eight digit serial number in the SENSOR_SN parameter does
not display the last two digits of the PROM ID stamped on the nameplate of
the transmitter housing. The Device ID contains the full 10-digit PROM ID.
