VEGAPULS 43 – Profibus PA 9
Product description
Adjustment with the PC
Generally, the set-up and adjustment of radar
sensors is most conveniently carried out on
the PC with the adjustment program
PACTware
TM under Windows ® . The program
leads quickly through adjustment and pa-
rameter setting by means of pictures, graph-
ics and process visualisations.
The adjustment software PACT ware TM acc. to
the FDT concept (Field Device Tool) operates
as an independent adjustment program on
any PC, engineering station or process con-
trol computer.
The adjustment program requires for com-
munication with Profibus sensors either a
Profibus-Master-Class2 interface card or the
interface adapter VEGACONNECT 3. The PC
with the Profibus interface card can be con-
nected directly to any point on the DP bus
with the standard RS 485 Profibus cable. In
conjunction with the adapter
VEGACONNECT, the PC can be connected
directly to the sensor. VEGACONNECT com-
municates via a small plug directly with the
individual sensor.
The adjustment and parameter data can be
saved at any time on the PC with the adjust-
ment software and can be protected by
passwords. If necessary, the adjustments
can be transferred quickly to other sensors.
In practice, the adjustment software
PACT
ware TM is often installed as a tool on an
engineering station or an operating station.
As a Master-Class 2 operating via the
Profibus interface card (e.g. from Softing), it
accesses VEGA sensors directly over the
bus, from the DP level to the PA level via the
segment coupler.
Beside the instrument master file (GSD), with
which a sensor is logged into the Profibus
system, most Profibus sensors require, in
addition to specific adjustment software, a
so-called EDD (Electronic Device Descrip-
tion) for each individual sensor, to enable
access and adjustment from the bus level.
