CONTROL DEVICE, CONTROL METHOD AND PROGRAM FOR CONTROLLING AN EQUIPMENT OR A MACHINE

摘要

A control device adopting a virtualization technique is provided. The control device includes: a real-time operating system (OS), executed using a hardware resource; a general purpose operating system (OS), executed using the hardware resource and operating independently of the real-time OS; and a hypervisor for managing the hardware resource allocated to the real-time OS and the general purpose OS. The control device includes a file sharing server function operating on the general purpose OS to reserve a part of a storage device as a storage area and share at least one part of the reserved storage area set by a user with another device; a function operating on the real-time OS to participate in the file sharing server function as a client through the hypervisor; and a function operating on the real-time OS to periodically monitor whether a shared area provided by the file sharing server function is accessible.
