1.1 Function and configuration
VEGALOG 571 is a modular processing
system for manifold applications in, for exam-
ple
- level measurement
- density measurement
- gauge measurement
- level detection
- process pressure measurement
- differential pressure measurement
- etc.
Suiting the application and meeting the indi-
vidual requirements, VEGALOG 571 is com-
posed of several module cards. One
CPU-card and peripheral cards are available
which are inserted into a carrier.
Function
VEGALOG 571 powers the connected sen-
sors and processes their analogue or digital
measuring signals or switching commands.
The peripheral cards take over the supply,
as well as the preparation of the measuring
signal for processing. The processing is
made in the CPU via special software con-
sisting of functional components (FB), input
components (EB) and output components
(AB). The input components receive the
measuring signals, the output components
provide them via the hardware outputs of the
peripheral cards or the CPU:
- as current signal 0/4 … 20 mA
- as voltage signal 0/2 … 10 V
- as relay/transistor contact
- as digital signal (RS 232-interface)
Adjustment surface
The adjustment of VEGALOG 571 is made by
a PC connected via an RS 232-cable to the
PC-interface of the CPU. The adjustment
software VEGA Visual Operating (VVO) is
installed under WindowsTM and enables the
easy configuration of measuring systems, as
well as the parameter adjustment of con-
nected VEGA-sensors. VVO offers a clear
adjustment surface with menu structure,
window technology and graphic support.
Configuration
VEGALOG 571 processing system consists
of a CPU, one or several peripheral cards, as
well as a power supply unit which can be
inserted in the 19“-carrier BGT LOG 571.
CPU and peripheral cards are module cards
in European size (DIN 41␣ 494) with 5␣ TE-
width (25,4␣ mm). The supply voltage of the
cards with 24␣ V␣ DC is provided, for example,
via a power supply unit VEGASTAB 593. The
carrier, with a width of 84␣ TE, and a height of
3␣ HE, corresponds to the 19“-standard for-
mat, is provided with an integral LOGBUS-
board for communication among the cards.
A VEGALOG can be equipped with a maxi-
mum of two carriers with a total of one CPU,
31 peripheral cards and a power supply unit.
Up to 255 measurement loops can be cre-
ated.

VEGA Visual Operating
This computer card is the centre of
VEGALOG and has the following functions:
- communication between the individual
cards
- calculating tasks such as scaling, linearisa-
tion, differential generation etc.
- coupling to the PC via RS 232-interface
Furthermore, the CPU is used for level detec-
tion or monitoring of switch on and off times.
Depending on the number of measurement
loops, CPU-cards in different performances
of up to 15, 30, 60 or 255 measurement loops
are available.
The CPU reads cyclically measured values
from the peripheral cards (with, for example,
30 measurement loops in 300␣ ms-cycle).
These are compared with the programmed
data, standardised and processed. The
programmed data (configuration data, ad-
justment parameters etc.) are available in the
EEPROM, where they remain even in case of
voltage loss. In the memory of the CPU a
process picture is created which is provided
to the peripheral cards via the LOGBUS.
For back-up, the programmed data can be
transferred via the RS 232-interface to the PC
and saved there on the hard drive or on a
diskette.
Input cards
EA-card
Up to 10 sensors can be connected to the
EA-card (input analogue) via active1) current
inputs 0/4␣ …␣ 20␣ mA:
- capacitive electrodes
- hydrostatic pressure transmitters
- vibrating level switches
- conductive electrodes
- process pressure and differential pressure
transmitters
- switching contact (level switch)

VEGALOG 571 7
Product description
The inputs can also be switched passively1)
and are used for connection of:
- switching contacts with additional current
source
- external current sources 0 … 20 mA
A mixed switching of active/passive1) inputs
is also permitted within an EA-card.

The EV-card (EV = input VBUS) powers up to
15 VBUS-sensors and processes their meas-
ured data:
- hydrostatic pressure transmitters
- ultrasonic sensors
- radar sensors
The digital communication between sensors
and the EV-card enables the connection of
different VBUS-sensors via common two-wire
line. This means that a transmission is avail-
able which is not only optimally adapted to
the conditions of the level measurement, but
also has increased immunity to interference.
In addition to the real transmission of meas-
ured values, it also enables the parameter
adjustment of the sensors via the signal con-
ditioning instrument from the control room
(local parameter adjustments are carried out
via the PC with VVO).
Separators
VEGATRENN 547V Ex
VEGATRENN 548V Ex
The separators are used for galvanic isola-
tion of the intrinsically safe from the not-intrin-
sically safe VBUS-measuring lines, and for
intrinsically safe supply and signal transmis-
sion of Ex-approved VBUS-sensors.

The scaling, as well as the definition as rising
or falling characteristics is made via the PC
with VVO.
Indicating instruments, recorders, controllers
or PLC-systems are connected to these
outputs.

The AD-card (AD = output DISBUS) brings
max. 15 measured values to one DISBUS-
line. Up to 30 VEGADIS 174 indicating instru-
ments can be connected to this line.
AR-card
The AR-card (AR = output relay) provides 10
relay outputs with floating spdt. The following
instruments can be connected:
- acoustic or optic signallers
- magnet valves
- contactors
- etc.
The AR-card is suitable for the output of level,
individual or collected fault signals. The
switching condition of each relay is indicated
via a two-coloured LED in the front facia. This
LED lights depending on the parameter ad-
justment of the relay as level contact or as fail
safe relay. Each fail safe relay can be indi-
vidually co-ordinated to one or several meas-
urement loops. The definition of the relay
function, the switch points, as well as the
LED-colour is made via the PC with VVO.
AT-card
The AT-card (AT = output transistor) provides
10 floating outputs via NPN-transistors. Bi-
nary input cards of PLC-systems are con-
nected.
The application possibilities and the signalling
of the switching condition correspond to the
AR-card.

Communication card
Product description
VEGACOM 557
The communication card VEGACOM 557 is
an interface converter (Gateway) for conver-
sion of VEGA-specific data formats into
standard protocols for connection of the
VEGALOG-system to a PLC or DCS. The
communication card is available for the fol-
lowing protocols:
- Siemens S5 (3964 R-procedure)
- Modbus (RTU and ASCII)
- Interbus S
- Profibus FMS
- Profibus DP
- VEGA-ASCII
The communication card can be used exclu-
sively to provide the data of VEGALOG to the
visualisation software Visual VEGA (VV). For
this purpose, the communication card is also
available without interface converter function.

1.6 Applications
A number of applications can be created in
VEGALOG with the VEGA Visual Operating
(VVO) adjustment software. On the following
pages you see applications with the appro-
priate sensors, mode and option.
VVO must be stated to create a new applica-
tion (measurement loop). Click in the main
window of VVO on Configuration, point to
Measurement loop and click on New. Then
confirm the adjustment “a new application“
with OK.
In the next window (“Create new measure-
ment loop -Application-“), you first choose the
application (e.g. level measurement), then the
sensor type (e.g. hydrostatic). Then click on
Continue>> and choose the mode (e.g.
pressurised vessel) and the option (e.g. real
value correction).
