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 Windows
TM 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.
