If the resistances of the devices connected to the power supply/signal line (voltage
source) are less than 250
Ω, a minimum resistance of 250 Ω must be installed in the
power supply line. The sum of the internal capacitances and inductances of the com-
ponents used must not exceed the highest permissible values of the ia IIC circuit.
10.2 Operation via PC and the software PACT ware 
The PACT ware  software with the necessary device driver (DTM) can be ordered
from WIKA. An integration in other HART ® management systems or FDT manage-
ment systems is possible.
Please note the different safety-related values according to the EC-type
examination certificate (see also chapter 6.7) and note the permissible
cable
length for devices with HART
®
communication.The termination resistor
in the loop must have a minimum value of 250 Ω.
The necessary operating software PACT ware  is described
in chapter 10.2.
