The method may involve accessing a memory card, the card having stored thereon a password, a parameter set, and a flag indicative of whether the parameter set is unique to the sensor. The method may involve determining, based on the flag, that the parameter set is not unique to the sensor. The method may involve determining whether the password stored on the card matches a sensor password of the sensor. The method may involve, in response to the password stored on the card matching the sensor password, writing a sensor serial number of the sensor onto the card. ## Claims ### Claim 1 A system configured to facilitate safety sensor configuration, the system comprising: an automated device comprising a safety sensor configured to perform a safety feature based on one or more sensor parameters, wherein a sensor serial number and a sensor password are linked with the safety sensor;
