5. CONFIGURATION
The BA644DF-F 8 variable FOUNDATION™
fieldbus 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. For detailed node conditioning
information please refer to the BEKA
FOUNDATION™ fieldbus Interface Guide which
may be downloaded from www.beka.co.uk
As a fieldbus listener the BA644DF-F 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 BA644DF-F push
buttons are identified
P E
▼ ▲ and legends
displayed by the fieldbus indicator are shown
within inverted commas e.g. ‘CodE’ and ‘LiSt’.
5.1 Configuration menus
The configuration menu is 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 FOUNDATION™ fieldbus
BA644DF-F indicators are supplied as fieldbus
nodes but can easily be reconfigured on-site.
5.2 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 BA644DF-F
is not protected by an access code the first
parameter 'rESEt’ 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 ‘rESEt’ to be displayed*.
If an incorrect code is entered, or no button is
pressed for ten seconds, the BA644DF-F will
automatically return to the display mode.
*
If the indicator displays ‘SCAn’ it is conditioned
as a fieldbus listener, see section 5.3.13 to change
it to a fieldbus node.
