The detail of the characteristics with respect to the HART

communication are available

in the corresponding “Field Device Specification” document.

To be able to use HART

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

modem can be connected are shown in the following

figure.
