1.3 Functions
The VEGACOM 557 interface converter can
be integrated into the VEGA level or pres-
sure measuring system in two different ways:
either
- as DISBUS participant
or
- as LOGBUS participant.
In both cases, VEGACOM 557 operates as
passive participant and provides measured
data and status information of the connected
VEGA signal conditioning instruments via the
Profibus DP. By the use of a standar dised
protocol (Profibus DP), it is possible to con-
nect via this interface any individual Profibus
DP compatible processing system.
Alternatively, it is possible to connect a PC
with VEGA adjustment software via the SUB-
D-plug marked “PC” on the front panel of
VEGACOM 557. VEGA adjustment software
is actually available as two different Windows
applications.
VVO = VEGA Visual Operating
For configuration and parameter adjust-
ment of the connected VEGAMET or VE-
GALOG processing systems
VV = Visual VEGA
For visualising and recording of measured
values of complete (multiple) vessel instal-
lations.
The following pictures show the basic con-
nection possibilities of VEGACOM 557.
