1. A software version control method comprising:

  • installing a software configurable component on an aircraft;

    automatically setting a listen switch of the software configurable component to an on state upon installation of the software configurable component in a new installation location, wherein the software configurable component does not command power outputs to a configuration manager on a power path while the listen switch is in the on state and wherein automatically setting the listen switch of the software configurable component to an on state comprises;

    reading a radio frequency identification (RFID) tag associated with the installation location to obtain a location tag value;

    comparing a previously read tag value with the location tag value; and

    setting the listen switch to the on state if the previously read tag value does not match the location tag value;

    manually setting the listen switch to an on state if no previous tag value has been read by the software configurable component;

    listening for a software version from the configuration manager on a communication bus;

    turning off the listen switch if a software version of the software configurable component matches the software version of the configuration manager; and

    downloading an updated software version to the software configurable component if the software version of the software configurable component does not match the software version of the configuration manager.
