  • 1. HART Multiplexer HART Multiplexer & & Application Application PEPPERL+FUCHS1 PROCESS AUTOMATION HART Multiplexer Topic
  • 2. PEPPERL+FUCHS2 PROCESS AUTOMATION
  • 3. HART Multiplexer What is HART Highway Addressable Remote Transducer HART is a fully open and de-facto communication protocol for process industries Almost 75%+ field transmitters are HART capable PEPPERL+FUCHS3 PROCESS AUTOMATION HART is the acronym for
  • 4. HART Multiplexer Communication Modes PROCESS AUTOMATION HART is a MASTER-SLAVE Communication Protocol SLAVE device communication is initiated by MASTER device SLAVE can be a Field Device and MASTER can be a DCS/PLC/PC/HHT 2 MASTERS is allow in the HART loop PEPPERL+FUCHS4
  • 5. HART Multiplexer Communication Modes PROCESS AUTOMATION HART also allow Burst Mode communication Burst Mode allow faster communication (3-4 data update per second) SLAVE continuously send reply message until MASTER instruct SLAVE to stop bursting PEPPERL+FUCHS5
  • 6. HART communication protocol use BELL 202 telephone communication standard BELL 202 is a FSK technology Super-impose sine wave on conventional 4/20 mA signal LOGIC 1 ≡1,200 Hz LOGIC 0 ≡ 2,200 Hz Communication speed (baud rate) = 1.2 kbps (1,200 baud) PEPPERL+FUCHS6 PROCESS AUTOMATION HART Multiplexer HART Physical Layer
  • 7. HART Multiplexer HART Physical Layer 1/1,200 sec 4/20 mA DC current -0,5 mA FSK LOGIC 1,200 Hz 2,200 Hz “1” Time “0” HART uses Frequency Shift Keying to encode digital information on top of the 4/20 mA analog signal PEPPERL+FUCHS7 PROCESS AUTOMATION +0,5 mA
  • 8. HART Multiplexer HART Physical Layer 1/1,200 sec A -0,5 mA B 4/20 mA DC current Time The current modulation for “A” is positive cycle and “B” is negative cycle. The resultant current or average current is zero. This meaning the FSK current modulation will not disturb the 4/20 mA DC current. PEPPERL+FUCHS8 PROCESS AUTOMATION +0,5 mA
  • 9. HART protocol has a min. sensitivity of 200 mV p-p. This also means that for 1 mA p-p (+0.5 mA to –0.5 mA) FSK current modulation, min. load is 200 Ω according to Ohm’s Law. HART specified load requirement for the loop 230 Ω … 1,100 Ω PEPPERL+FUCHS9 PROCESS AUTOMATION HART Multiplexer HART Load Requirement
