6.2.3 Access code for node 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
configuration menu by operating the
▼
or
▲
button. To enter the function press P which 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 E to enter
the selection and return to the ‘CodE’ prompt in the
configuration menu. The revised access code will
be activated when the indicator is returned to the
display mode.
If the access code is lost please contact BEKA
associates.

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 BA448CF-F
listener are not known.
In the ‘SCAn’ function pressing the P button
causes the BA448CF-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 P button will preview the value of the data at
each selected address, if required it may then be
allocated to one of the eight BA448CF-F listener
inputs in-1, to in-8 by operating the P button 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 BA448CF-
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.
