2.2. HART
PCON-Y17 can be used to read and set parameters in devices that have HART
Communication Protocol. The HART
master (in this case, PCON-Y17) and the slave (field instrument) superimposed on the 4-
20 mA analog signal. To access this function from the main menu, select the HART
option.

The HART
has three versions: NH (without HART
®
(Full-HART
configurator with DD library).
The CH option has basic and universal commands for HART
(zero, span, trim mA etc.) that allow you to adjust the range of the instrument, monitoring
the primary variable, current adjustment etc. The FH option, in addition to basic and
universal commands, is provided with the DD library (Device Description) from
FieldComm Group and allows the setting of specific parameters of each instrument.
The following description is valid for CH and FH options.

Connections
When selecting HART
HART (INCLUDING NETWORK) options are shown. An internal resistor (250 Ω) Can
also be enabled or disabled. The option must be chosen according to the type of
connection to be made.
