Claims (9)

  1. A status notification device (1, 10), configured to change an output between two values depending on whether an object is detected, wherein the status notification device (1, 10) is a multiple optical axis photoelectric sensor (1) comprising a light receiver (10), the status notification device (1, 10) further comprising: a monitoring unit (500) that is a status sensor monitoring at least one of an operating status of the status notification device (1, 10) and an environment surrounding the status notification device (1, 10) based on a physical vibration status or a voltage level of a supply voltage in the status notification device (1, 10); and a log output unit (160) that outputs a log (Lo) comprising a monitoring result of the physical vibration status or the voltage level of the supply voltage in the status notification device (1, 10) of the monitoring unit (500) upon a change as a normal operation in the output of the status notification device (1, 10).
  2. The status notification device (1, 10) according to claim 1, wherein the object is detected by a non-contact sensor.
  3. The status notification device (1, 10) according to claim 1 or 2, wherein the object is detected by the multiple optical axis photoelectric sensor (1), and the log output unit (160) outputs the log (Lo) for identifying a status detected by each of a plurality of light receiving elements (200) of the multiple optical axis photoelectric sensor (1) at a time when the output of the status notification device (1, 10) is changed.
  4. The status notification device (1, 10) according to any one of claims 1 to 3, further comprising a memory unit (300) that stores in advance the log (Lo) output by the log output unit (160).
  5. The status notification device (1, 10) according to any one of claims 1 to 4, further comprising a transmission unit (600) that transmits the log (Lo) output by the log output unit (160) to the outside.
  6. The status notification device (1, 10) according to any one of claims 1 to 5, further comprising an acceptance unit (700) that accepts a user operation and stops the log output unit (160) from outputting the log (Lo).
  7. A control method for a status notification device (1, 10), configured to change an output between two values depending on whether an object is detected, wherein the status notification device (1, 10) is a multiple optical axis photoelectric sensor (1) comprising a light receiver (10), the control method for a status notification device comprising: a monitoring step of monitoring, by a status sensor of the light receiver (10), at least one of an operating status of the status notification device (1, 10) and an environment surrounding the status notification device (1, 10) based on a physical vibration status or a voltage level of a supply voltage in the status notification device (1, 10); and a log output step of outputting a log (Lo) comprising a monitoring result of the physical vibration status or the voltage level of the supply voltage in the status notification device (1, 10) of the monitoring step upon a change as a normal operation of the monitoring step upon a change as a normal operation in the output of the status notification device (1, 10).
  8. An information processing program for causing a computer to function as the status notification device (1, 10) according to any one of claims 1 to 6, wherein the information processing program is for causing the computer to function as each part of the status notification device.
  9. A computer-readable recording medium, having the information processing program according to claim 8 recorded therein.

Description

Technical Field The present invention relates to, for example, a status notification device configured to change an output according to a detected status. Related Art Conventionally, a status notification device configured to change an output according to a detected status, such as a multiple optical axis photoelectric sensor or the like, has been known. For example, the multiple optical axis photoelectric sensor outputs a high-level signal while a detection area is not shielded, and stops the output upon detecting that the detection area is shielded. Besides, it is known that this status notification device is configured to notify the outside of occurrence of an abnormality which occurred in the status notification device or the like. For example, Patent literature 1 described below discloses a multiple optical axis photoelectric sensor that notifies the outside of an abnormality which occurred during muting processing. Citation List Patent Literature Patent Literature 1: Japanese Patent Laid-Open No. 2012-134575EP 2654061 Al relates to a multi-axis photoelectric sensor that outputs a high-level signal while a detection area is not shielded and stops the signal output when the detection area is shielded.The document WO 2019/176305 A1 discloses a multi-optical axis photoelectric sensor and a determination device that determines abnormalities in the sensor. SUMMARY OF INVENTION Technical Problem However, the conventional technique as described above has a problem in that when a status notification device such as the multiple optical axis photoelectric sensor or the like executes an output change as a normal operation, it is difficult for a user to ascertain the cause of the output change. For example, the conventional status notification device saves an operation log only when an abnormality occurred in the operation of the status notification device, and does not save an operation log when an "output change" is executed as a normal operation. Therefore, the conventional status notification device has a problem in that when the "output change" is executed as a normal operation of the conventional status notification device, the user cannot use the operation log of the conventional status notification device when examining the cause of the "output change" or the like. The invention is set out in the appended set of claims. The following disclosure serves a better understanding of the present invention. One aspect of the present invention has been made in view of the above-described problems, and an objective is to allow the user to easily ascertain the cause of an "output change" of a status notification device configured to execute an "output change" according to a detected status. Solution to Problem In order to solve the above problems, a status notification device according to one aspect of the present invention is a status notification device configured to change an output between two values depending on whether an object is detected, the status notification device including: a monitoring unit that monitors at least one of an operating status of the status notification device and an environment surrounding the status notification device; and a log output unit that outputs a log including a monitoring result of the monitoring unit upon a change in the output of the status notification device. In order to solve the above problems, a control method for a status notification device according to one aspect of the present invention is a control method for a status notification device configured to change an output between two values depending on whether an object is detected, the control method for a status notification device including: a monitoring step of monitoring at least one of an operating status of the status notification device and an environment surrounding the status notification device; and a log output step of outputting a log including a monitoring result of the monitoring step upon a change in the output of the status notification device. Effects of Invention One aspect of the present invention has the effect of allowing a user to easily ascertain the cause of a change in the output of a status notification device configured to change an output according to a detected status.
