ApaApa ituitu HART?HART?
HART merupakan singkatan dari “HighwayAddressable Remote Transducer ” yang bisaditerjemahkan sebagai Transducer berada padaremote area (jauh) . HART adalah sebuah protokolyang dikembangkan oleh Rosemount yang dibuat
er asar an stan ar omun as e 20 .merupakan open protokol yang berarti dapatdigunakan dan dikembangkan oleh siapapun.HART memiliki dua modulasi sekaligus dalamkomunikasinya yaitu menggunakan analog (4-
20mA) dan Digital yaitu FSK (Frequency ShiftKeying).

HART protocolHART protocol Selain itu protokol HART juga menggunakan
modulasi digital untuk berkomunikasi dengan caramengirimkan data serial yang di modulasi dengan
FSK (Frequency Shift Keying). data Analog dikonversi kedalam digital kemudian dikirimkan
me a u ser a ne an mo u as . e e umnya,FSK adalah sebuah metode penyisipan datamelalui gelombang sinyal dengan cara
menyisipkan frekuensi. pada komunikasi HART,
Frekuensi yang digunakan adalah 2200 Hz dan1200Hz. frekuensi 2200Hz diterjemahkan
sebagai ’0′ dan 1200Hz diterjemahkan sebagai
’1′ .
