1 Sensor
2 HART resistance 250 Ω (optional depending on evaluation)
3 Adapter cable for HART modem
4 Processing system/PLC/Voltage supply
5 HART modem
Note:
For power supply units with integrated HART resistance (inner resist-
ance approx. 250 Ω), there is no additional external resistance neces
-
sary. Standard Ex separators are often provided with a sufficiently
high current limitation resistance. In such cases, the modem can be
connected in parallel to the 4 … 20 mA cable.
7.2 Parameter adjustment
The further setup steps with detailed descriptions can be found in the
online help of PACTware and the DTMs.
Note:
Keep in mind that for the setup of device, the current version of the
DTM Collection must be used.
The latest DTM Collection and PACTware version can be downloaded
free of charge via the Internet.
7.3 Saving the parameterisation data
We recommend documenting or saving the parameterisation data via
PACTware. That way the data are available for multiple use or service
purposes.
