VEGA VEGACONNECT 3 - Manual (Page 7)

3.2 Principle of operation
VEGACONNECT 3 is an interface converter for connecting
communication-capable VEGA instruments to the RS232
interface of a PC or modem. It can be also used as universal
HART modem for sensors of other manufacturers. For
parameter adjustment of these instruments, an adjustment
software such as PACTware™ with VEGA DTM or VEGA
Visual Operating (VVO) is required. The Visual VEGA software
can be used for remote enquiry of measured values.
VEGACONNECT 3 can be connected to the VEGA instru-
ments listed below. All currently available protocol versions are
supported. These are: HART, Profibus PA, Foundation
Fieldbus, VBUS (optional).
l
VEGAPULS radar sensors
l
VEGASON ultrasonic sensors
l
VEGAFLEX guided microwave
l
VEGABAR process pressure transmitter
l
Pressure transmitter D series
l
Capacitive electrode EL/EK
l
VEGADIS indicating instruments
l
VEGAMET signal conditioning instruments
VEGACONNECT 3 is available in two versions:
l
CONNECT 3.X: Standard version without VBUS interface
l
CONNECT 3.V: Version with additional VBUS interface
Two adapters and terminals for connection to different instru-
ment series are attached to each VEGACONNECT 3.
The VEGACONNECT 3 interface converter is connected via
an RS232 connection to a PC or an external modem. It
converts the signals and protocols of the RS232 interface into
the corresponding signal/protocol of the connected instrument.
The following systems are supported:
l
4 … 20 mA with superimposed HART protocol
l
Profibus PA via I²C protocol
l
Foundation Fieldbus via I²C protocol
l
VBUS (only with the option additional VBUS interface)
Power supply is provided via the control cables of the RS232
interface of the PC or modem. In a few cases, it may happen
that the gauges of the control cables are not sufficient for
power supply of VEGACONNECT 3. In this case, power
supply can be carried out via a standard, separate power
supply unit (e.g. Friwo EP1). A protective low voltage in the
