maintenance personnel to handle profile-based devices without a special tool configuration This International Standard gives manufacturers and other organizations the common set of functionality to represent their network capable devices Manufacturers or other organizations may use the root device profiles specified to add their manufacturer-specific extensions BS EN 61915-2:2012 61915-2 ©
