TTF300 FIELD-MOUNT TEMPERATURE TRANSMITTER | CI/TTF300-EN REV. H 41
FOUNDATION Fieldbus® Communication
Note
The FOUNDATION Fieldbus® protocol is an unsecured protocol,
as such the intended application should be assessed to ensure
that these protocols are suitable before implementation.

On device using LCD indicator
Voltage / current consumption
• Average current consumption:12 mA.
In the event of an error, the FDE function (= Fault
Disconnection Electronic) integrated in the device makes
sure that the current consumption cannot exceed a
maximum of 20 mA.
Basic Setup
Note
The communication and configuration of the transmitter via
HART®, PROFIBUS PA®, and FOUNDATION Fieldbus H1® are
described in the separate documentation “Interface Description”
for the relevant protocol (COM/TTX300/...).
The following configuration types are available for the
transmitter:
• With DTM:
Configuration can be performed within an FDT frame
application that is approved for use with the DTM.
• With EDD:
Configuration can be performed within an EDD frame
application that is approved for use with the EDD.
• With FDI-Package (FIM):
Configuration is possible within an FDI frame applications
(Field Information Manager / FIM) for which the FDI
packages are released.
• With LCD indicator Type A with operating buttons
Commissioning via the LCD indicator does not require any
tools to be connected to the device and is therefore the
simplest way of configuring the TTF300 .
The general operation and menus of the LCD indicator are
described in Menu navigation on page 42.
Note
Unlike configuration using the DTM, EDD or FDI-Package (FIM)
the functionality of the transmitter can only be changed to a
limited extent with the LCD indicator.
