1. A method of updating the program of a gas compressor system
which has a plurality of gas compressors,
a controller that controls the plurality of gas compressors, wherein each of the plurality of gas compressors store a program and the plurality of gas compressors comprises a first gas compressor, a second gas compressor, and a third gas compressor,
and
a control terminal that controls the controller of the plurality of gas compressors, wherein gas is controlled by the controller by at least one of a predetermined pressure value and a predetermined flow rate of the gas value, the method comprising:
obtaining a program update,
updating a first program of the first gas compressor that is a target of the program update among the plurality of gas compressors, and
operating at least one of the second or the third gas compressor based on the predetermined pressure value and the predetermined flow rate of the gas value.
