  • HART modem and diagnostic system
    Patent number: 11509748
    Abstract: A HART modem includes: a HART/Host communication conversion unit, which relays communication between a HART device and a HART host device; a communication waveform detection unit configured to generate data sampled from HART communication signals transmitted and received to and from the HART device; and a communication interface unit configured to transmit the data generated by the communication waveform detection unit to the HART host device.
    Type: Grant
    Filed: November 10, 2020
    Date of Patent: November 22, 2022
    Assignee: AZBIL CORPORATION
    Inventors: Naoki Furusawa, Mamoru Kagoura, Naoyuki Fukao, Hiroyuki Tsugane
  • Hart modem and diagnostic system
    Patent number: 11415966
    Abstract: A HART modem includes: a HART/Host communication conversion unit, which relays communication between a HART device and a diagnostic device or a host device; a communication waveform detection unit configured to record data sampled from HART communication signals transmitted and received to and from the HART device in a communication waveform temporary storage unit; a communication content monitoring unit configured to monitor contents of HART communication and instruct the communication waveform detection unit to start recording and stop the recording of data according to a signal acquisition timing specified by a user; and a waveform acquisition management unit configured to transmit data accumulated in the communication waveform temporary storage unit to the diagnostic device when the recording of the data is stopped.
