Next, the operation of the communicator 1 having the above-described configuration will be described with reference to FIGS. 6 and 7. It is assumed that the user carries the communicator 1 and is working at the place where the field device 5 is installed at the site.

First, the biometric information acquisition unit 11 acquires the biometric information of the user detected by the sensor 111 (step S1). Specifically, as shown in FIG. 7, the user's fingerprint is acquired by the user touching the sensor 111 provided with the fingerprint sensor with a finger. Next, the transmission / reception unit 10 transmits the acquired biometric information of the user to the server 3 via the communication network NW (step S2).

After that, the authentication result receiving unit 12 receives the result of the biometric authentication executed on the server 3 (step S3). More specifically, the authentication result receiving unit 12 receives information indicating that the authentication of the user's biometric information has been successful. In addition, the authentication result receiving unit 12 receives information including the user ID and the language used by the user in addition to the authentication result. If the user authentication fails, the process ends.

After that, the language acquisition unit 13 identifies the language used by the extraction unit 15 from the information received in step S3 (step S4). Next, when the voice receiving unit 14 receives the voice data by the voice uttered by the user (step S5: YES), the extraction unit 15 manages the preset field device 5 using the specified language information.

After that, the device information acquisition unit 18 acquires the response to the instruction information, that is, the device information (processing result) from the field device 5 (step S9). For example, when the instruction information is a command for confirming the PV value of the field device 5, the PV value is acquired from the field device 5 as the device information.

Next, the conversion unit 17 converts the device information acquired from the field device 5 into voice data based on the language used by the user (step S10). For example, when the language used by the user specified in step S4 is Japanese, the device information is converted into Japanese voice data. After that, the voice output unit 19 outputs the voice data of the device information by voice (step S11). For example, as shown in FIG. 7, a voice such as "The PV value of P00 is ##" is output from the speaker 110.

Next, the display unit 20 displays the device information acquired in step S9 on the display screen (step S12). For example, as shown in FIG. 7, on the display device 108, the same information as the voice output from the speaker 110, such as "PV value of P00 is ##", is displayed by the text information.

As a result, it is possible to perform device management such as setting the field device 5 and confirming the setting by reducing the situation where the user in the field is obstructed.

If a certain period of time elapses after receiving the authentication result in step S3 (step S13: YES), the user's voice is not received in step S5, and the process ends.
