5.3 EMC
The BA444DF-P complies with the requirements of
the European EMC Directive 2004/108/EC. For
specified immunity, all wiring should be in
screened twisted pairs with the screens earthed at
one point in the safe area.

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 E buttons 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 P will allow the
four digit security code to be entered digit by digit
using the
▼
or
▲
button to adjust the flashing digit
and P to move control to the next digit. When the
correct code has been entered, pressing E will
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 P to 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 P button will transfer control
to the next digit that may be adjusted in the same
way. When all digits are set as required operating
the E button 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 E button 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.
