System program optimization device, system program optimization system, and computer-readable storage medium

A system program optimization system, comprising:

• an information processing device, comprising
• a constant value setting unit that accepts setting of a constant value for an external input signal input from an external device which is connected to a numerical controller, and
• a constant value output unit that outputs the constant value to a system program optimization device;
• and
• a system program optimization device for managing a system program of a numerical controller, comprising
• a constant value acquisition unit that acquires a constant value set for an external input signal input from the external device connected to the numerical controller, and
• a compiler that translates source code of the system program into an object program that can be executed by the numerical controller,
• wherein the compiler comprising an optimization unit that optimizes the system program by using the constant value of the external input signal.

A storage medium which stores instructions readable by one or more processors,

• the one or more processors executing the instructions to:
• acquire a constant value set for an external input signal input from an external device which is connected to a numerical controller;
• compile source code of a system program of the numerical controller into an object program that can be executed by the numerical controller;
• and
• optimize the system program by using the constant value of the external input signal in the compiling process.
