PROBLEM TO BE SOLVED: To enable an operator on a job site to recognize that unitary management is performed by a device for equipment management.SOLUTION: Disclosed is HART(Highway Addressable Remote Transducer) communication correspondence equipment 1 having an HART communication function for transmitting and receiving an HART communication signal to be generated by superimposing an AC signal in which frequency signals of 1200 Hz and 2200 Hz are combined with DC signals of 4 to 20 mA. The HART communication correspondence equipment 1 includes: a reception part 11 for receiving the HART communication signal; a signal detection part 12 for detecting the AC signal of the HART communication signal by using the HART communication signal received by the reception part 11; and an indicator part 17 for displaying that the AC signal is detected while the AC signal is detected by the signal detection part 12. |
