Abstract
A light receiver outputs a log indicating at least one of an operating status of a multiple optical axis photoelectric sensor and an environment surrounding the multiple optical axis photoelectric sensor, at the time of an output being turned off.
Claims8
A status notification device, configured to change an output between two values depending on whether an object is detected, comprising:
- 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 based on at least one of a physical vibration status, a generation status of noise in signal output, a generation status of optical noise, and a voltage level of a supply voltage in the status notification device;
- and
- a log output unit that outputs a log comprising a monitoring result of at least one of the physical vibration status, the generation status of noise in signal output, the generation status of optical noise, and the voltage level of the supply voltage in the status notification device of the monitoring unit upon a change in the output of the status notification device at least during a normal operation.
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 comprising:
- 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 based on at least one of a physical vibration status, a generation status of noise in signal output, a generation status of optical noise, and a voltage level of a supply voltage in the status notification device;
- and
- a log output step of outputting a log comprising a monitoring result of at least one of the physical vibration status, the generation status of noise in signal output, the generation status of optical noise, and the voltage level of the supply voltage in the status notification device of the monitoring step upon a change in the output of the status notification device at least during a normal operation.
