Smart Electronics Operation Using
PC
The Commubox FXA 191 connects
4…20 mA Smart transmitters that have a
HART protocol to the RS 232 C serial
interface of a personal computer. This
enables the transmitter to be remotely
operated with the Hauser
Commuwin II operating program.
You can connect the Commubox
FXA 191 at any point along the
4…20 mA line. It is also suited for
connection to intrinsically-safe signal
circuits.
Connecting to PROFIBUS-PA
PROFIBUS-PA is an open fieldbus
standard to enable serveral sensors and
actuators, including those in
explosion-hazardous areas, to be
connected to bus line. With
PROFIBUS-PA, two-wire looped
instruments can be supplied by the
sensor with power and digital process
information.
The number of instruments operated by
one bus segment is:
•
up to 10 for Ex ia applications
•
up to 32 for all further applications
(e.g. non-Ex, EEx nA)
