The detail of the characteristics with respect to the HART TM communication are available
in the corresponding “Field Device Specification” document.
To be able to use HART
TM communication, a resistance (R ext.), whose value must not
be lower than 200 Ohms, should be added to the current loop. The points at which a
terminal or a PC with a HART
TM modem can be connected are shown in the following
figure.
