The IFC 300 is a “four-wire” transmitter with 4...20mA current output and HART® capability. Dependent on
jumper setting and/or wiring the current output can operate as active or passive output.
General characteristics of the IFC 300 HART® interface:
• Multidrop Mode is supported
• Burst Mode is not supported
Electrical connection: Refer to section “Electrical connection: outputs and inputs” of the following manual:
•“Handbook IFC 300 signal converter” (KROHNE)
There are two ways of using the HART® communication:
a) As a point-to-point connection between the IFC 300 and the HART master equipment. The instrument' s
b) As a multipoint connection (multidrop) with up to 15 devices (IFC 300 or other HART® equipment) in
parallel. The instrument's current outputs must be passive.
In case the IFC 300's current output shall work continuously active a 'third wire' is needed to properly
connect it together with two-wire loop powered devices in the same network.

3 Inputs/Outputs and HART Dynamic/Transmitter Variables
The IFC 300 is available with a choice of output/input assemblies (see details in the section "I/O assemblies
for the outputs and inputs" of the “Handbook IFC 300 signal converter” (KROHNE)):
The assignment of the I/O terminals (A, B, C and D) to the HART Dynamic Variables (PV, SV, TV and FV)
depends on the device's I/O option:
HART Dynamic Variables:
PV SV TV FV
Basic I/O terminals: A D - Modular I/O and
EEx–i I/O terminals:
The IFC 300 transmitter handles up to 10 measurement-related HART Transmitter Variables but the sub -set
of available variables depends on the device's I/O option and its configuration:

HART Transmitter Variable Code
To Dynamic Variables which are tied to linear analogue outputs (i.e. current outputs and frequency outputs)
the HART Transmitter Variables are assigned by selecting the 'measurement' (Fct. C2.x.5) for these outputs.
(E.g. when selecting the 'measurement' volume flow for current output A of a device with Basic IO the HART
Transmitter Variable Volume Flow is assigned to the HART Dynamic Variable PV). This implies that only
Transmitter Variables of linear type can be assigned to Dynamic Variables tied to current or frequency
outputs. (A totaliser variable e.g. can't be assigned to PV, the HART current output)
For Dynamic Variables not tied to linear analogue outputs there is no such correlation: Both linear
and totaliser type Transmitter Variables can be assigned (Fct. C4). (Therefore a totaliser variable
e.g. can be assigned to SV, TV and FV unless the respective output is a current or frequency
output.)
There are some parameters (namely measurement counter 1..3 and diagnosis value selection)
which, after they have been changed, require a warm start of the device e.g. for updating dependent
units parameters, before any other parameters may be written. Dependent on the characteristics
and capabilities of the HART host system (e.g. online-/offline-orientation) these parameters are
treated differently (see details below).
5 Field Communicator 375 (FC375)
5.1 Installation
The IFC 300 HART Device Description has to be installed on the FC375 respectively. Otherwise the user will
work with the instrument as a generic one thus loosing opportunity for entire instrument control.
For installing DDs on the FC375 the ‘Easy Upgrade Programming Utility’ is needed and the FC375 mu st
have a System Card with ‘Easy Upgrade’ option (see details in the ‘375 Field Communicator User’s Manual’).
5.2 Operating
Refer to the IFC 300 Menu Tree FC375 (Attachment A).
The IFC 300 operation via FC375 is made quite close to the manual instrument control via keypad with the
restriction that parameters of the device's "service" menu are not supported and simulation is possible only
for current outputs. The online help of each parameter contains its function number as a reference to the
device’s local display and the “Handbook”.
Parameter protection for custody transfer is the same as on the device's local display. Other specific
protection mechanisms like "password quick setup" and "password setup" are not supported via HART.
The FC375 always creates a “full” configuration for interaction with AMS. Still the FC375 considers only a
partial parameter set (like the “standard configuration” in the HART Communicator HC275) when sending it
to a device.
Basic Configuration Parameters:
In online mode the counter measurement and diagnosis value settings can be changed with the
corresponding methods located in the menu tree below the related parameter. When editing an offline
configuration these parameters are read only, however they are written to the device when sending an offline
configuration
6 Asset Management Solutions (AMS)
6.1 Installation
If the IFC 300 Device Description is not already installed on the AMS System a so called Installation Kit IFC
300 HART AMS is needed (available as download from KROHNE ‘Download Center’ on the internet or on
floppy disk / CD-ROM from KROHNE).
For installing the DD with the Installation Kit refer to the “AMS Intelligent Device Manager Books Online"
section "Basic AMS Functionality /Device Configurations / Installing Device Types / Procedures /Install device types from media”. Please read also the “readme.txt”, which is also contained in the Installation Kit.
6.2 Operating
Refer to the IFC 300 Menu Tree AMS (Attachment B).
Due to AMS requirements and conventions the IFC 300 operation differs to some extent from operation with
FC375 and via local keypad. Furthermore parameters of the device's "service" menu are not supported and
simulation is possible only for current outputs. The online help of each parameter contains its function
number as a reference to the device’s local display and the “Handbook”.
Parameter protection for custody transfer is the same as on the device's local display. Other specific
protection mechanisms like "password quick setup" and "password setup" are not supported via HART.
Basic Configuration Parameters:
In online mode the counter measurement and diagnosis value settings can be changed with the
corresponding methods located in the "Basic Configuration" menu. When editing an offline configuratio n
these parameters are read only.
7 Process Device Manager (PDM)
7.1 Installation
If the IFC 300 Device Description is not already installed on the PDM System a so called Device Install IFC
300 HART PDM is needed (available as download from KROHNE ‘Download Center’ on the internet or on
floppy disk / CD-ROM from KROHNE).
For installing the DD on PDM V 5.2 refer to the “PDM Manual” section 11.2:”Device Install / Integrating Devices in SIMATIC PDM with 'Device Install'".
For installing the DD on PDM V 6.0 refer to the “PDM Manual” section 13:”Integrating Devices”.
Please read also the “readme.txt”, which is also contained in the Device Install.
7.2 Operating
Refer to the IFC 300 Menu Tree PDM (Attachment C).
Due to PDM requirements and conventions the IFC 300 operation differs to some extent from operation with
FC375 and via local keypad. Furthermore parameters of the device's "service" menu are not supported and
simulation is possible only for current outputs. The online help of each parameter contains its function
number as a reference to the device’s local display and the “Handbook”.
Parameter protection for custody transfer is the same as on the device's local display. Other specific
protection mechanisms like "password quick setup" and "password setup" are not supported via HART.
Basic Configuration Parameters:
In the PDM offline Parameter Table the counter measurement and diagnosis value settings can be changed
directly and dependent units parameters are updated automatically. However in Online Dialogs of the PDM
Parameter Table an automatic update isn't possible.
8 Field Device Tool Device Type Manager (FDT DTM)
8.1 Installation
If the IFC 300 Device Type Manager is not already installed on the Field Device Tool container a setup is
needed (available as download from KROHNE ‘Download Centre’ on the internet or on CD-ROM from
KROHNE).
For installing the DTM with the setup refer to the setup’s accompanying documentation.
8.2 Operating
The IFC 300 operation via DTM is made quite close to the manual instrument control via keypad. Refer to
the device’s local display and the “Handbook”.
