A rotary machine has stationary upper and lower housings with circumferential grooves and a rotatable component, as well as annular sealing segments movable toward and away from the rotating components between large and small clearance positions. Each of these groups can be connected via an assigned local two-conductor data line to a two-conductor master data line whose conductors are connected to the input terminals of a secondary read amplifier. includes disassembling a binary file and determining functions in the disassembled binary file. The laser beam generator generates a laser beam, which is used to isolate one of the defects.
