摘要：
A numerical controller that collects data from an industrial machine and writes data into a storage medium includes: an interval setting unit that sets a time interval between cycles in which one cycle involves collection of operation information indicating an operating state of the industrial machine and writing of the collected operation information to the storage medium; a reduced service life calculation unit that calculates a service life of the number of writes of the storage medium reduced by the writing on the basis of the set time interval as a reduced service life; a determining unit that determines whether the calculated reduced service life exceeds a prescribed threshold; and a signal output unit that outputs a signal indicating that the reduced service life exceeds the prescribed threshold when it is determined that the reduced service life exceeds the prescribed threshold.
