Title: CONTROL DEVICE, CONTROL METHOD AND PROGRAM FOR CONTROLLING AN EQUIPMENT OR A MACHINE
Abstract: 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.

Claims: number: 1
text: A control device (100) for controlling an equipment or a machine, comprising:
number: 2
text: The control device (100) according to claim 1, wherein in a program operating on the real-time OS (114), a command enabling access to the shared area is available.
number: 3
text: The control device (100) according to claim 1 or 2, wherein in a program operating on the real-time OS (114), information showing whether or not the shared area is accessible is referenceable.
number: 4
text: The control device (100) according to any one of claims 1 to 3, comprising:
number: 5
text: The control device (100) according to claim 4, comprising:
number: 6
text: The control device (100) according to any one of claims 1 to 5, comprising:
number: 7
text: The control device (100) according to claim 6, comprising:
number: 8
text: The control device (100) according to any one of claims 1 to 7, wherein access to the storage area reserved by the real-time OS (114) from an application executed by the general purpose OS (116) is prohibited.
number: 9
text: The control device (100) according to any one of claims 1 to 8, wherein the file sharing server function (1162) is configured to enable the shared area to be shared with another device different from the control device (100).
number: 10
text: The control device (100) according to any one of claims 1 to 9, wherein the hypervisor (112) establishes a logical connection between the real-time OS (114) and the general purpose OS (116).
number: 11
text: The control device (100) according to any one of claims 1 to 10, wherein the storage device (110) comprises a plurality of types of memory devices; and
in a program operating on the real-time OS (114), a command enabling selective access to the shared area and the storage area of each of the plurality of types of memory devices is available.
number: 12
text: A control method in a control device (100) controlling an equipment or a machine, the control method comprising:
number: 13
text: A program containing a real-time OS (114) capable of constructing an environment for controlling an equipment or a machine, wherein
the real-time OS (114) uses a hardware resource comprising one or more processors (102) and storage devices (110) and is executed in parallel with a general purpose OS (116) operating independently of the real-time (114) OS under a hypervisor (112) managing the hardware resource, and
a file sharing server function (1162) operating on the real-time OS (114) reserves a part of the storage device (110) as a storage area, and shares at least one part of the reserved storage area set by a user with another device, wherein
the program comprises:
