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.

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.
