1. DESCRIPTION
The BA444DF-P fieldbus indicator is an intrinsically
safe, PROFIBUS PA instrument, that may be
configured as a fieldbus node or as a fieldbus
listener. It can display up to eight fieldbus process
variables on a five digit LCD and a 31 segment
analogue bargraph. The instrument is bus
powered so no additional power supply is required
and has PROFIBUS PA User Organisation
approval, certificate Z01505.
Fieldbus node configuration may be performed by
either a User PRM data download or by a DPV1
configurator, and if required, the instrument
address may be entered via the front panel push
buttons.
When configured as a fieldbus listener, the
BA444DF-P is not visible to the fieldbus host and
can only be configured using the push buttons on
the front of the instrument.
Housed in a robust IP66 glass reinforced polyester
(GRP) enclosure with a toughened glass window,
the BA444DF-P is surface mounting, or may be
pipe mounted using one of the accessory kits.
The instrument has been certified intrinsically safe
by European Notified Body Intertek Testing and
Certification Ltd (ITS) for use in explosive gas and
combustible dust atmospheres. ATEX dust
certification is an option – see Appendix 1.
For use in the USA and Canada, the BA444DF-P is
available with intrinsic safety and nonincendive FM
and cFM Approval – see Appendix 2.
For international applications, all versions of the
BA444DF-P PROFIBUS PA indicator have IECEx
intrinsic safety approval allowing installation in
explosive gas atmospheres. IECEx dust
certification is available as an option – see
Appendix 3.
The instrument’s communication protocol is shown
on a label inside the terminal cover. The ‘-P’ order
code suffix also indicates the protocol but is not
shown on the instrument certification label.
There is an alternative version of the fieldbus
display, order code BA444DF-P for use on
FOUNDATION™ fieldbus networks.
1.1 Documentation

4. SYSTEM DESIGN FOR HAZARDOUS
AREAS
4.1 FISCO Systems
The BA444DF-P fieldbus indicator may be
connected to any ATEX certified FISCO compliant
fieldbus segment, providing the segment can
supply the additional 13mA required to operate the
instrument.
Fig 1 shows a typical fieldbus segment. To comply
with FISCO requirements, the power supply,
terminators, field devices and the interconnecting
cables must conform with IEC60079-11.
Fig 1 FISCO fieldbus system
4.2 Ex ia entity systems
The BA444DF-P Fieldbus Indicator has Ex ia
certification with entity parameters for applications
in Zone 0, 1 and 2.
The BA444DF-P Fieldbus Indicator may be
connected to any intrinsically safe segment
providing:
The device powering the fieldbus segment is
ATEX Ex ia certified for Zone 0, 1 or 2
applications, or Ex ib certified for application
in Zone 1 or 2, or Ex ic certified for
applications in Zone 2. The output
parameters of the segment should be equal
to or less than:
Uo = 22V dc
Io = 250mA dc
Po = 1.2W
The segment can provide an additional 13mA
to power the Fieldbus Indicator.
The equivalent capacitance Ci of the
BA444DF-P Fieldbus Indicator is zero and
the equivalent inductance is insignificant.
Therefore these BA444DF-P parameters do
not need to be considered.
4.3 Ex ic entity systems
The BA444DF-P Fieldbus Indicator also has Ex ic
certification with entity parameters for applications
in Zone 2. The higher Ui voltage allows the
indicator to be used with segment couplers
powered by Ex e or Power-i fieldbus trunks.
When mounted in Zone 2 the BA444DF-P Fieldbus
Indicator may be connected to any intrinsically safe
segment providing:
The device powering the fieldbus segment is
ATEX Ex ia, ib or ic certified and has output
parameters equal to or less than:
Uo = 32V dc
Io = 125mA dc
Po = 1W
The segment can provide an additional 13mA
to power the Fieldbus Indicator.
The equivalent capacitance Ci of the
BA444DF-P Fieldbus Indicator is zero and
the equivalent inductance is insignificant.
Therefore these BA444DF-P parameters do
not need to be considered.

manual enable the instrument to be mounted onto
a vertical or horizontal pipe.
The field terminals and the two mounting holes are
located in a separate compartment with a sealed
cover allowing the instrument to be installed
without exposing the display assembly.
The BA444DF-P earth terminal is connected to the
carbon loaded GRP enclosure. If this enclosure is
not bolted to a post or structure connected to the
plant potential equalising network, the instrument’s
earth terminal should be connected to the
potential equalising network as recommenced in
EN 60079-14.
The BA444DF-P enclosure is supplied with a
bonding plate to ensure electrical continuity
between the three conduit / cable entries.

6. CONFIGURATION
The BA444DF-P 8 variable PROFIBUS PA PA
indicator may be configured as a fieldbus node or
as a fieldbus listener. When used as a fieldbus
node the indicator is configured via the fieldbus
host although the instrument address may be
entered via the front panel push buttons using the
menu shown in Fig 4. For detailed node
conditioning information please refer to the BEKA
PROFIBUS PA Display – Fieldbus Interface Guide
which may be downloaded from the BEKA website
www.beka.co.uk
As a fieldbus listener, the BA444DF-P is not visible
to the fieldbus host and can only be configured via
the front panel push buttons using the menu shown
in Fig 6.
Throughout this manual the four BA444DF-P push
buttons are identified P E ▼▲and legends
displayed by the instrument are shown within
inverted commas e.g. ‘CodE’ and ‘Enb’. 6.1
Configuration menus
The configuration menus are separated into two
sections, fieldbus node and fieldbus listener. Both
contain the ‘tYPE’ function that enables transfer
between the two. Unless otherwise requested
when ordered, all PROFIBUS PA BA444DF-P
instruments are supplied as a fieldbus node with
default configuration but can easily be reconfigured
on-site.
6.2 Node configuration menu
The node configuration menu is shown in Fig 4.
Access to the menu is obtained by operating the P
and Ebuttons simultaneously. If the BA444DF-P is
not protected by an access code the first
parameter 'Addr’ will be displayed. If the
instrument 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 ‘Addr’ to be displayed.
If an incorrect code is entered, or no button is
pressed for ten seconds, the BA444DF-P will
automatically return to the display mode.
6.2.1 Enter fieldbus address ‘Addr’
This function enables the fieldbus address of the
BA444DF-P to be entered via the push buttons.
Select ‘Addr’ in the node menu using the ▼or ▲
button and press Pto enter the function. This will
reveal the existing three digit decimal address with
the left hand digit flashing which may be changed
by operating the ▼or ▲button. When set as
required operating the Pbutton will transfer control
to the next digit that may be adjusted in the same
way. When all digits are set as required operating
the Ebutton will enter the new address and the
indicator will restart in the display mode after
completing the initialisation sequence. If the
address is not changed, operating the Ebutton will
return the display to the ‘Addr’ prompt in the node
configuration menu.
6.2.2 Access code for configuration menu
‘CodE’
Access to the node configuration menu may be
protected by a four digit security code which must
be entered to gain access. New instruments are
supplied configured with the default code 0000
which disables this protection and allows
unrestricted access to the configuration menu.To
enter a new access code select ‘CodE’ in the node
configuration menu by operating the ▼or ▲
button. To enter the function press Pwhich will
reveal the current access code with one digit
flashing. The code may be changed using the ▼or
▲button to adjust the flashing digit and the P
button to move control to the next digit. When the
required code has been selected, press Eto enter
the selection and return to the ‘CodE’ prompt in the
configuration menu. The revised access code will
be activated when the transmitter is returned to the
display mode.
If the access code is lost please contact BEKA
associates.
6.2.3 Change from node to listener ‘tYPE’
This function enables the instrument to be changed
from a fieldbus node to a fieldbus listener. Select
‘tYPE’ in the node configuration menu using the ▼
or ▲button. To enter the function press Pwhich
will show that the instrument is configured as a
fieldbus node, to change to a fieldbus listener
press the ▼or ▲button which will toggle the
display to ‘LStnr’ To prevent accidental changes
this request must be confirmed by operating the P
button and entering ‘5urE’. The instrument will
display ‘0000’ with the first digit flashing, using the
▼or ▲button set the flashing digit to ‘5’ and press
the Pbutton to move control to the next digit which
should be set to ‘u’. When the four letters of ‘5urE’
have been entered, operating the Ebutton will
cause the instrument to restart as a fieldbus
listener in the display mode.
CAUTION
All the instrument’s node configuration
information will be lost when it is
changed from a fieldbus node to a
fieldbus listener.

FIG 4 Node configuration menu
6.3 Listener configuration menu
When used as a fieldbus listener the BA444DF-P
is not visible to the fieldbus host and can only be
configured using the front panel push buttons
shown in Fig 3.
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 addresses of the data sources to be displayed
by the BA444DF-P listener are not known.
In the ‘SCAn’ function pressing the Pbutton
causes the BA444DF-P listener to search the
fieldbus segment to which it is connected for all
data sources. The hexadecimal device
addresses for each data source are displayed as
shown in Fig 5.
The ▼and ▲push buttons scroll the display
through all the data sources on the segment
showing the source and destination address for
each one. To aid identification, operating the P
button will preview the value of the data at the
selected addresses with a zero index i.e. the first
five bytes in the data string. If the format of the
data is not DS-33 (status + float) ‘no dAt’ will be
displayed. The selected source and destination
addresses may be allocated to one of the eight
BA444DF-P listener inputs in-1, to in-8. Operating
the Pbutton will reveal the current listener input
which may be changed using the ▼or ▲push
button, when set as required, operating the Epush
button will enter the allocation. If the process
variable to be displayed is located further along the
data stream i.e. has an index greater than 5, the
required index must be entered via the index ‘ind’
function in the edit sub-menu.
A worked configuration example illustrating this
procedure is contained in the Quick Set-up section
of the PROFIBUS PA Interface Guide.
Fig 5 Device Addresses
If the source and destination addresses and index
of the process variable to be displayed by the
BA444DF-P listener 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 BA444DF-P listener
configuration menu is not protected by an access
code the first parameter 'SCAn’ will be displayed.
If the BA444DF-P 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.
Section 6.3.2 contains a summary of each
configuration function including a cross reference
