The BA644DF-P may be reset to the factory
defaults that are shown below:
Security Code
Device address
For each of the eight inputs:
Decimal point
Bar Type
Bar lower limit
Bar Upper limit

Offset
To reset the BA644DF-P select 'rESEt' in the
configuration menu by operating the ▼ or ▲
button.
To enter the function press P which will
reveal '0000' with the left hand digit flashing. To
prevent accidental use of this function, '5urE' must
be entered to confirm that the instrument is to be
reset.
Using the ▼ or ▲ button set the flashing digit to '5'
and press the P button to move control to the next
digit which should be set to 'u'. When the four
letters of '5urE' have been entered operating the E
button will reset the BA644DF-P to the factory
defaults.
Any
existing
addresses will be lost when the instrument is reset.

5.3 Listener configuration menu
When used as a fieldbus listener the BA644DF-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 BA644DF-P listener are not known.
In the 'SCAn' function pressing the P button
causes the BA644DF-P listener to search the
fieldbus segment to which it is connected for all
data sources.
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.
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.
and

displayed.
addresses may be allocated to one of the eight
BA644DF-P listener inputs in-1, to in-8. Operating
the P button will reveal the current listener input
which may be changed using the ▼ or ▲ push
button, when set as required, operating the E push
button will enter the allocation.
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 BEKA PROFIBUS PA Display – Fieldbus
Interface Guide.
If the source and destination addresses and index
of the process variable to be displayed by the
BA644DF-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.
