TTF300 FIELD-MOUNT TEMPERATURE TRANSMITTER | OI/TTF300-EN REV. I 43
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.

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 B 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 45.
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.
