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.

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.

Abstract: An instrument status display displaying on a screen, in a tree format, respective indicators corresponding to instruments controlled in a hierarchical structure, having an installation time mark acquiring portion acquiring, as an applicable installation time mark, a time mark that is nearest to a reference time mark without being later than the reference time mark, where the time mark is a time mark for the connection of an instrument, from an installation/removal event history database; an alert event acquiring portion acquiring alert event information notified from an instrument over the interval from the applicable installation time mark, acquired by the installation time mark acquiring portion, up until the reference time mark; a display formatter determining a display format of an indicator based on alert event information; and a displaying portion displaying, on a screen, an indicator in a display format determined by the display formatter.

Abstract: An instrument controlling device includes a storing portion that stores relationally parameter information, identification information that can identify, as a group, the selected plurality of instruments, and storage date and time information for when the parameter information was stored by the group unit. The instrument controlling device also includes a list displaying portion that displays a list of instruments, an information extracting portion that extracts, from the parameter information stored by the storing portion, the parameter information for the instruments belonging to the same group as an instrument that is indicated, when there has been an instruction to display history information of the parameter information corresponding to one of the instruments among the instruments displayed by the list displaying portion, and an information providing portion that provides, in a state that can be viewed by the user, the parameter information extracted by the parameter extracting portion.
