®
Connection
The DPI 610E supports 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.
The HART function is only available on
CH2
. The function uses 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 DPI 610E can be used to communicate with HART devices as a:
Primary Master
- the DPI 610E starts and controls all communications. The field device (slave)
uses each command from the master device to make a change and/or send data back.
Secondary Master
- the DPI 610E connects to an existing HART communications network. The
Secondary Master communicates with the field device between Primary Master messages.
