Abstract
A numerical controller includes a programmable controller that performs input and output of a signal based on a ladder program and performs control of a machine based on an NC program. The numerical controller includes a first table associating the function used for control of the machine, an input signal, and an output signal and a second table associating the input signal, the output signal, and a signal in a dependent relation with the input signal and the output signal. Based on a function code of a function commanded by a block of the NC program that is preread, the numerical controller refers to the first and the second tables, identifies a signal to be subjected to automatic trace, and performs trace.
