7 Setup with PACTware
POINTRAC 31 • 8/16 mA/HART - four-wire
39411-EN-131119
•
POINTRAC 31
•
PC with PACTware and suitable VEGA DTM
•
VEGACONNECT 4
•
HART resistance approx. 250 Ω
•
Voltage supply
Note:
With power supply units with integrated HART resistance (internal
resistance approx. 250 Ω), an additional external resistance is not
necessary. This applies, e.g. to the VEGA instruments VEGATRENN
149A, VEGAMET 381 and VEGAMET 391). Commercially available
Ex separators are also usually equipped with sufficient current limita-
tion resistance. In such cases, VEGACONNECT 4 can be connected
parallel to the 4 … 20 mA cable.
7.2 Parameter adjustment with PACTware
For parameter adjustment of the sensor via a Windows PC, the con-
figuration software PACTware and a suitable instrument driver (DTM)
according to FDT standard are required. The up-to-date PACTware
version as well as all available DTMs are compiled in a DTM Collec-
tion. The DTMs can also be integrated into other frame applications
according to FDT standard.
Note:
To ensure that all instrument functions are supported, you should
always use the latest DTM Collection. Furthermore, not all described
functions are included in older firmware versions. You can download
the latest instrument software from our homepage. A description of
the update procedure is also available in the Internet.
Further setup steps are described in the operating instructions manu-
al "DTM Collection/PACTware" attached to each DTM Collection and
which can also be downloaded from the Internet. Detailed descrip-
tions are available in the online help of PACTware and the DTMs.
