Description of HART interface
8.1 General description
The open HART
®
protocol, which can be used for free, is integrated into the sensor for
communication.
Devices which support the HART
®
protocol are classified as either operating devices or field
devices. When it comes to operating devices (Master), both manual control units (Secondary
Master) and PC-supported workstations (Primary Master) are used in, for example, a control
center.
HART
®
field devices include sensors, signal converters and actuators. The field devices range
from 2-wire to intrinsically safe versions for use in hazardous areas.
The HART
®
data are superimposed over the analogue 4...20 mA signal via FSK modem. This way,
all of the connected devices can communicate digitally with one another via the HART
®
protocol
while simultaneously transmitting the analogue signals.
When it comes to the field devices and secondary masters, the FSK or HART
®
modem is
integrated. If a PC is used, an external modem must be connected to the serial interface
(USB interface). There are, however, other connection variants which can be seen in the
following connection figures.
