NCR-80 Four-wire 4-20 mA/HART
925-0332 Rev B
7 Setting up sensor and Modbus interface with PACTware

Necessary components:
●
NCR-80
●
PC with PACTware and suitable VEGA DTM
●
Interface adapter
●
HART resistance approx. 250 Ω
●
Processing system/PLC
Note:
With power supply units with integrated HART resistance (internal resistance approx. 250 Ω), an
additional external resistance is not necessary. Commercially available Ex separators are also
usually equipped with sufficient current limitation resistance. In such cases, inteface adapter can
be connected parallel to the 4 … 20 mA cable.
7.2 Parameter adjustment
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 Collection. 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 manual "
DTM Collection/
PACTware
" attached to each DTM Collection and which can also be downloaded from the Inter-
net. Detailed descriptions are available in the online help of PACTware and the DTMs.
