•
PC with PACTware and suitable VEGA DTM
•
VEGACONNECT
•
Power supply unit or processing system

1 VEGASON 61
2 HART resistance 250 Ω (optional depending on evaluation)
3 Connection cable with 2 mm pins and terminals
4 Processing system/PLC/Voltage supply
Necessary components:
•
VEGASON 61
•
PC with PACTware and suitable VEGA DTM
•
VEGACONNECT 4
•
HART resistance approx. 250 Ω
•
Power supply unit or processing system
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, VEGADIS 371, VEGAMET 381. Common Ex separators are
also usually equipped with a sufficient current limitation resistance.
In such cases, VEGACONNECT 4 can be connected parallel to the
4 ... 20 mA cable.

Parameter adjustment with PACTware

For parameter adjustment of the instrument via a Windows PC, the
configuration software PACTware and a suitable instrument driver
(DTM) according to FDT standard are required. The latest 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
