When updating the control program by a device capable of selecting one among two control programs and executing the program, the time required for updating the program is shortened by reducing the amount of data to be transferred. The present invention includes: a first rewritable storage unit in which two programs are stored; a CPU that selects and executes one among the two programs; and a second rewritable storage unit in which shared data associated with the two programs is stored.

    在由能够选择2个控制程序中的一个来执行的装置更新控制程序时,减少转送的数据量而缩短程序的更新所需要的时间。具有:第1可改写存储部,其存储2个程序;CPU,其选择所述2个程序中的某一个并执行;以及第2可改写存储部,其存储所述2个程序中附带的共通的数据。
