Numerical controller including reduced memory service life calculation unit, numerical control system, and non-transitory computer readable recording medium

A non-transitory computer readable recording medium having a program recorded thereon, the program causing a computer to function as a numerical controller that collects data from an industrial machine and writes data into a storage medium, the computer functioning as:

• 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 service life information acquisition unit that acquires service life information indicating a remaining service life;
• a determining unit that determines whether a calculated remaining service life after reduction exceeds a prescribed threshold wherein the remaining service life after reduction is determined by the calculated reduced service life in relation to a difference between the acquired remaining service life and the calculated reduced service life exceeds the prescribed threshold by determining whether an expression is satisfied as follows
• (Threshold %)<((Reduced service life)/[(Remaining service life)−(Reduced service life)]=(Remaining service life after reduction))×100;
• and
• a signal output unit that outputs a signal indicating that the remaining service life after reduction exceeds the prescribed threshold when it is determined that the remaining service life after reduction exceeds the prescribed threshold.
