12. HART® Communication
HART® is a registered trademark of HART Communi-
cation Foundation. HART® communication is a digital
method for data communication between a field instru-
ment and the HART® host device (terminal or control
system). HART® communication is implemented by
applying FSK-modulation compatible with the Bell202
modem standard; in this method, a high-frequency
communication signal is incorporated in a DC-level
measurement signal. The average level of the FSK-
signal is zero, and thus it does not distort the 4–20 mA
measurement signal.
The HART communicator is connected parallel to
the current signal line, for example to the HART
connectors on the kajaaniMCAi Display Unit. From
version V1.4 upwards, the kajaaniMCAi software is
provided with device-specific HART programming. In
addition, the HART communicator must contain the
kajaaniMCAi command set. Without the command set,
only the standard HART communications are avail-
able, and these are not sufficient for start-up and calibra-
tion. The MCAi’s HART software tree is illustrated in
Fig. 12.2.
To access a function with the HART communicator,
select the function with the cursor and then press the
RIGHT arrow (functions provided with an arrow sym-
bol) or function key [F4] E
NTER
(functions with no
arrow symbol). The data configured on the display can
be sent to the MCA
i
by pressing [F2] S
END
or [F4] OK.
