Here, FIG. 3 is a block diagram showing an example of a schematic configuration of a manufacturing system including the recorder 1 described above. A management device 22 (external device) is connected to the recorder 1 of the manufacturing system 21 in FIG. The recorder 1 is communicably connected to the lower end via the recorder 1. Further, a controller 23B is connected below the controller 23A, and a controller 23C is connected below the controller 23B. That is, in the manufacturing system 21 of FIG. 3, three sets of controllers 23A, 23B, and 23C are connected in a daisy chain to one recorder 1 as external devices. A heater 26A in the manufacturing apparatus 25 is connected to the controller 23A via a power controller 24A, and a temperature sensor 27A in the manufacturing apparatus 25 is also connected to the controller 23A.

The identification code is received and the identification code of the portable external communication medium is authenticated.

When the identification code of the portable external communication medium 19 is successfully authenticated, the communication program startup process (ST2) includes processing details written in the identification code (for example, acquisition of updated data from the last 12 hours or the last acquisition up to the present time). A program is started on the recorder 1 to execute (such as outputting daily report data in a predetermined format).

When the program is started in the recorder 1, data communication is performed between the recorder 1 and the portable external communication medium 19 via the short-range wireless module 13 (ST3).

When the data communication is completed, as communication program termination processing (ST4), the program of the recorder 1 is terminated, the authentication state of the portable external communication medium 19 is canceled, and data processing processing is executed as necessary ( ST5). As the data processing process, for example, a work history such as a daily report is created based on the data received by the portable external communication medium 19. Note that when the recorder 1 outputs a report by specifying the output format using the identification code, data processing is not necessary.

Incidentally, in the above-described embodiment, the digital recorder 1 that displays on the display screen a waveform based on measurement data indicating changes in physical quantities such as temperature, current, and voltage of the object to be measured has been illustrated and explained. It may be an analog recorder that prints a waveform or the like indicating a change in a physical quantity on a long recording paper, or a hybrid recorder that uses both digital and analog methods.

As described above, according to the present embodiment, the short-range wireless module 13 and the communication means 14 perform various controls on the recorder 1 based on information acquired from the external communication medium 18, the portable external communication medium 19, and the external device.
