摘要
The object is to provide a data processing apparatus, a program managing apparatus, a program managing system, etc., capable of securely and efficiently updating and managing a control program in the data processing apparatus. The data processing apparatus analyzes received data and when program updating data sent from a superior rank apparatus is acquired, temporarily stores program data for updating out of such data in a storage device. Upon occurrence of an event of a program updating request, the data processing apparatus executes updating processing based on the updating program data stored in the storage device and, after completion of the program updating, gives a notice of updating completion to the superior rank apparatus and again waits for the event. Timing of the program updating request is set later than that of the program updating data being sent from the superior rank apparatus.
