Numerical controller and data editing method

A numerical controller that uses a simulation screen displayed on a display unit so as to edit operation data of an industrial machine, the numerical controller comprising:

• an editing data storage unit that stores editing data in which an operation target and an operation type and setting screen data including an editing item are associated with each other;
• a touch operation reception unit that receives a touch operation by a user on the simulation screen;
• an operation identifying unit that identifies the operation target and the operation type on the simulation screen by the touch operation received in the touch operation reception unit;
• a setting screen data extraction unit that references the editing data storage unit so as to extract the setting screen data corresponding to the operation target and the operation type identified by the operation identifying unit;
• an editing processing unit that edits the setting screen data extracted by the setting screen data extraction unit;
• and
• a setting screen output unit that outputs, to the display unit, the setting screen data after being edited by the editing processing unit.
