AREAS
4.1 FNICO Systems
The BA444NDF-F may be connected to any ATEX
certified FNICO compliant FOUNDATION™
fieldbus segment, providing the segment can
supply the additional 13mA required to power the
instrument.
Fig 1 shows a typical fieldbus segment. To comply
with FNICO requirements, the power supply,
terminators, field devices and the interconnecting
cables must conform to the requirements specified
in EN 60079 part 27.
Fig 1 FNICO FOUNDATION™ fieldbus system
4.2 Non-FNICO Systems
As shown in section 3.3 the BA444NDF-F also has
entity input parameters. The indicator complies
with the requirements for ‘Self protected energy-
limited apparatus’ as defined by Clause 30.1
Paragraph b of EN 60079-15. This means that the
BA444NDF-F contains its own current limiting
components and may be connected to any Type
nL certified associated apparatus irrespective of its
Io providing:
Uo of the Type nL certified associated
apparatus is equal to or less than 36V which is
the Ui of the BA444NDF. Note: maximum
operating voltage is 32V.
C cable + sum of Ci of all other instruments
connected to the segment is equal to, or less
than, Co of the Type nL associated apparatus
powering the fieldbus segment to which the
BA444NDF-F is connected.
L cable + 8µH + sum of Li of all other
instruments connected to the segment is equal
to, or less than, Lo of the Type nL associated
apparatus powering the fieldbus segment to
which the BA444NDF-F is connected.
The fieldbus segment can provide an additional
13mA at between 9 and 32V to power the
BA444NDF-F Profibus Indicator.
These requirements are not restrictive and allow
the BA444NDF-F 8 variable FOUNDATION™
fieldbus indicator to be connected to almost all
Type nL fieldbus segments powered by Type n
associated apparatus or Zone 2 mounted segment
isolators.

6.3 Listener configuration menu
The listener configuration menu is separated into
three sections, ‘SCAn’, ‘LISt’ and ‘Edit’, plus three
housekeeping functions ‘CodE’, ‘tYPE’ and ‘rESEt’
as shown in Fig 6.
‘SCAn’ is the simplest method of configuration if
the fieldbus Device Address and Variable Identity
of the data to be displayed by the BA444NDF-F
listener are not known.
In the ‘SCAn’ function pressing the Pbutton
causes the BA444NDF-F indicator to search the
fieldbus segment to which it is connected for all
publishers. Fig 5 shows how the indicator displays
the hexadecimal Device Address and Variable
Identity associated with each publisher.
A Publisher is a device that places it's output
data onto the bus as part of a cyclical pre-
determined data exchange schedule.
The Device Address is a unique address that
identifies each fieldbus instrument connected to
the bus.
The Variable Identity is the fieldbus device
Data Link Connection End Point (DLCEP)
which identifies each Function Block output
(process variable) transmitted by a fieldbus
device such as flow and temperature
transmitted by a fieldbus flowmeter.
The ▼and ▲push buttons scroll the display
through all the publishers on the segment showing
the Device Address and Variable Identity for each
one - see Fig 5. To aid identification, operating
the Pbutton will preview the value of the data at
each selected address, if required it may then be
allocated to one of the eight BA444NDF-F listener
inputs in-1, to in-8 by operating the Pbutton again.
If the format of the data at the selected Device
Address and Variable Identity is not DS-65 (float +
status) ‘no dAt’ will be displayed.
Fig 5 Device Address and Variable Identity
If the Device Address and Variable Identity of the
process variable to be displayed by the
BA444NDF-F indicator are known, they may be
directly entered via the edit sub-menu. This sub-
menu also provides full control of both the numeric
and bargraph display parameters.

6.3.1 Access
Access to the listener configuration menu is
obtained by operating the Pand Ebuttons
simultaneously. If the BA444NDF-F is not
protected by an access code the first parameter
'SCAn’ will be displayed.*If the indicator is
protected by an access code, ‘CodE’ will be
displayed first. Pressing Pwill allow the four digit
security code to be entered digit by digit using the
▼or ▲button to adjust the flashing digit and Pto
move control to the next digit. When the correct
code has been entered, pressing Ewill cause the
first parameter ‘SCAn’ to be displayed.*If an
incorrect code is entered, or no button is pressed
for ten seconds, the indicator will automatically
return to the display mode.
* If the indicator displays ‘rESEt’ it is conditioned
as a fieldbus node, see section 6.2.2 to change it
to a fieldbus listener.

6.3.3 Scan fieldbus segment ‘SCAn’
If the Device Address and Variable Identity of a
process variable are not known, the ‘SCAn’
function provides a simple way to identify them.
This function scans the fieldbus segment to which
the BA444NDF-F indicator is connected and
identifies all the publishers. To aid identification it
enables the value of each process variable to be
pre-viewed and, if required, allocated to one of the
eight BA444NDF-F Fieldbus indicator inputs.
The BA444NDF-F indicator only supports DS-65
formatted data (float + status) which is the usual
format for analogue process variables. The
‘SCAn’ function will identify all publishers on the
segment irrespective of format, but when pre-
viewed, non DS-65 formatted data will produce a
‘no dAt’ error message.
‘SCAn’ is the first function displayed when entering
the listener configuration menu, or it may be
selected from within the menu by operating the ▼
or ▲button. To scan the fieldbus segment to
which the indicator is connected for all published
data press Pwhich will reveal the hexadecimal
Device Address and Variable Identity of the first
publisher found as shown in Fig 5. If there is
more than one publisher operating the ▼or ▲
button will scroll though all of them.
If no cyclic data is being published on the fieldbus
segment the BA444NDF-F indicator will display
‘noPub’.
When the Device Address and Variable Identity of
a process variable is being displayed, pressing P
will preview the value of the process variable
displayed with maximum resolution on the five digit
display. If this confirms that it is one of the
process variables to be displayed, it may be
allocated to one of the eight BA444NDF-F listener
inputs in-1 to in-8.
To select the required indicator input press Pto
display the first input in-1, operating the ▼or ▲
button will scroll the display through the other
inputs. When the required input is displayed
pressing Ewill allocate the selected process
variable to the selected input and return the display
to the Device Address and Variable Identity from
which another process variable may be selected.
When a process variable is allocated to a indicator
input any previous allocation will be overwritten.
6.3.4 List configured input parameters ‘LiSt’
The ‘LiSt’ function enables the Device Address and
Variable Identity allocated to each lindicator input
to be viewed without danger of it being accidentally
changed.
The ‘LiSt’ function may be selected from within the
menu by operating ▼or ▲button. To enter the
function press Pwhich will display the indicator
input currently selected in the display mode, other
inputs may be selected using the ▼or ▲button.
Operating the Pbutton will cause the following
parameters for the selected input to be displayed
sequentially:
Display Explanation
‘Enb: Y or N’ Input Enabled yes or no
‘Adr: 00’ Device Address
‘id: 00’ Variable Identity
The display then automatically returns to the
selected BA444NDF-F indicator input from where
another input may be selected.
If one of the eight BA444NDF-F indicator’s inputs
in-1 to in-8 has not had a Device Address and
Variable Identity allocated to it, ‘LiSt’ will show both
as invalid address FF.

7.2 Fault finding after commissioning
ENSURE PLANT SAFETY BEFORE
STARTING MAINTENANCE
Live maintenance is permitted on FNICO
systems, but should only be performed on
non-FNICO systems when there is no risk
of a flammable atmosphere being present.
The BA444NDF-F terminal cover should
only be removed when dust and water can
not enter the enclosure. Before replacing
the terminal cover ensure that the sealing
gasket is undamaged and that it is free
from foreign bodies.
If a BA444NDF-F fails after it has been functioning
correctly, the table shown in section 7.1 may help
to identify the cause of the failure.
If this procedure does not reveal the cause of the
fault, it is recommended that the instrument is
replaced.

associates name and location. IECEx dust
approval information is also shown.
The instrument serial number and date of
manufacture are recorded on a separate label
inside the terminal compartment.
A1.3 Installation & maintenance
WARNING
The Fieldbus non-incendive concept
(FNICO) only applies to installations in
flammable gases. Live working is
therefore not permitted on installations in
combustible dusts.
The BA444NDF-F ATEX dust certification
relies on the Fieldbus Indicator enclosure
being dust-tight. Therefore the terminal
cover should only be removed when dust
can not enter the instrument enclosure.
Before replacing the terminal cover
ensure that the sealing gaskets are
undamaged and are free from foreign
bodies.
