Configuring the interface
Configure the UniCOM universal data
interface for its intended operating
mode in the operating menu of the
indicator (connecting a peripheral
device or a second weighing platform
/ digital compact scale). The applicable
section of the menu tree is shown on
the previous page.
The "Configuration" section of the
Signum operating instructions contains
further explanations about this.
RS-485/RS-422 interface
If the board is configured for RS-422
operation, the "SBI", "XBPI-232" and
SMA settings in the menu can be used.
YDO0...-AO analog interface
(Option A9)
The following can be configured in the
menu:
– Output value (menu item 8.12):
8.12.1: Net value
(factory setting)
8.12.2: Gross value
– Error indicator (menu item 8.13):
8.13.1: High level (20 mA)
(factory setting)
8.13.2: Low level (0/4 mA)
– Output mode (menu item 8.14):
8.14.1: Zero to maximum load
(factory setting)
8.14.2: Min./max. values
– Output min./max. values
(menu item 8.15):
8.15.1: Min. (0/4 mA) input in kg
8.15.2: Max. (20 mA) input in kg
By selecting: Min./max. values, the
weighing range for the 0/4 to 20 mA
(0 to 10 V) output can be defined as
desired. This selection also applies for
an SBI balance/scale, but only for the
net value.
The min./max. values are always entered
using kilograms as a unit. It is possible
to enter negative weight values. It is
also possible for the min. value to be
larger than the max. value if descending
current output is desired.

Examples:
Ascending current curve
Min. value, net: -1 kg
Max. value, net: 4 kg
Descending current curve for xBPI
balance/scale
Min. value: 5 kg
Max. value: 1 kg
Descending current curve for SBI
balance/scale
Min. value: 5 kg
Max. value: 1 kg
If no calibration parameters were
entered, the interface operates as
configured on the hardware, i. e. if
the hardware is configured as 0 – 24
mA, the minimum value is transmitted
as 0 mA and the maximum value is
transmitted as 24 mA. The output is
only set to 4 –20 mA by entering at
least one calibration value.
If the menu item "4mA measured
value:" or "20mA measured value:" is
enabled, the unadjusted current values
are transmitted, although a calibration
value may be displayed.
The calibrated measurement value is
only displayed after a measurement
value is entered.
e.g.: The menu item is enabled and
"3.98" is displayed. The current
interface now transmits "3.98 mA".
After again entering "3.98" the
interface transmits precisely "4.00 mA".
The calibrated 4mA value is displayed
on exiting the menu items.
Attention:
During the switch-on procedure for
3
the Combics terminal the interface
may briefly transmit 24 mA.
Please note that the customer may
only connect analog interfaces which
can withstand 24 mA to the Combics
current interface.
Profibus interface
In the "UNICOM" menu, select
"PROFIBUS" to set the bus address
(0 to 126; factory setting: 126). If
application data are also transmitted,
34 bytes are attached to the 8 byte
standard interface. In this way applica-
tions can be initialized or written in
the display (see additional "Field bus"
documentation).
Ethernet interface
In the "UNICOM" menu, select
"ETHERNET" to enter numerical
values under Source IP, ListenPort, etc.
Under Source name, both letters and
numbers can be used. A maximum of
15 characters can be entered. Enter
either a source name or a source IP
address (not both).
Port numbers
Validity range: 0 – 65535
Since many of the ports up to 49150
have already been allocated, we
recommend using port numbers
above 49150. This does not apply to
Modbus/TCP, because the following
port number applies here: 502 (See
the "Field bus" brochure for details)
