This alarm indicates that an invalid teach-in operation was attempted for a KRL program object, specifically related to type mismatch or incompatible data structure (error code 2340). The robot controller rejected the teach-in command because the object being modified does not support the operation or the data type is incompatible with the requested teach-in procedure.
