Control device for industrial machine

A control device for an industrial machine, the control device being adapted for data access via an API, and comprising:

• a data storage unit configured to store data for use for operation;
• a save-and-storage unit configured to store data not for use for operation;
• and
• a control unit,
• the control unit comprising
• an operation start detection unit configured to detect a start of operation for machining for the industrial machine,
• a data saving unit configured to cause data stored in the data storage unit to be saved in the save-and-storage unit, and
• an operation status acquisition unit configured to acquire an operation status of the control device, wherein
• the control device saves data in the save-and-storage unit before the start of the operation for machining to thereby increase a number of access destinations to two including the data storage unit and the save-and-storage unit, and makes it less likely for the operation and the API or at least two APIs to simultaneously access same data while the machining is in operation.
