6. CONFIGURATION
The BA448CF-P 8 variable PROFIBUS 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 BA448CF-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 BA448CF-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 BA448CF-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 BA448CF-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 BA448CF-P will
automatically return to the display mode.
6.2.1 Enter fieldbus address ‘Addr’
This function enables the fieldbus address of the
BA448CF-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.
To enter a new access code select ‘CodE’ in the
node 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 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 P
which 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 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
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.
Please refer to the quick set-up procedure in the
BEKA PROFIBUS PA Display – Fieldbus Interface
Guide.
