6.2.12 HART
The DPI 610E can use the
HART
(Highway Addressable Remote Transducer) communication
protocol and allows basic HART operation and configuration on HART supported devices. The
HART bi-directional communications technology works as a master/slave protocol and when
connecting the DPI 610E to the HART device, the DPI 610E acts as the master and the HART
device, the slave. The DPI 610E supports commonly used functions from the Universal and
Common Practice commands specified in HART revision 5, 6 and 7. (See more on HART in
Chapter 12 on page 206).
The HART function is only available on
CH2
. As it utilizes the current loop signal for its
communication, the DPI 610E can provide 10 V/24 V loop power supply to the HART device if
required.
The DPI 610E also offers an optional 250-ohm resistor that provides the voltage drop required
for the HART communication when an external HART resistor is not available.
The HART resistor can be enabled (and disabled) from the
CH2
Setup
window.
To select the
HART
function:
Step 1
From the Calibrator screen, select the
channel 2
Setup (either tap the
screen icon or press the softkey.)
Step 2
Select
FUNCTION
from the
CH2
Setup
screen.
