Abstract: A system configuration information management device includes a storage device configured to store therein control system identification information, component identification information, and version information in association with one another. The control system identification information identifies a control system. The component identification information identifies each of a plurality of components composing the control system. The version information indicates a version of an element of each of the components having at least hardware.

Abstract: An engineering tool includes a hardware-allocation-data storage, an allocation-condition storage, and a tool processor. Hardware allocation data is to be downloaded to a controller that executes a host operating system (OS), and represents hardware allocation to each of the host OS and a guest OS that runs on a virtual machine implemented on the host OS. The allocation-condition storage stores therein hardware allocation conditions for the host OS and the guest OS. The tool processor causes a display to display a settings screen for inputting the hardware allocation data; after determining that the input hardware allocation data satisfies the allocation conditions stored in the allocation-condition storage, saves the input hardware allocation data in the hardware-allocation-data storage; and after determining that the input hardware allocation data fails to satisfy the allocation conditions, refrains from saving the input hardware allocation data therein.

Abstract: A control device according to an embodiment includes hardware. The hardware includes a memory and a processor. The memory stores a host operating system (OS), a virtual machine, a guest OS, a guest process, and a controller process. The virtual machine is implemented on the host OS. The guest OS operates on the virtual machine. The guest process unit is operated by the guest OS, and executes control processing for an external appliance to be controlled using the hardware that is allocated to the guest OS in accordance with hardware allocation data indicating hardware to be allocated to each of the host OS and the guest OS. The controller process unit is operated by the host OS, and executes control processing for the appliance to be controlled using the hardware that is allocated to the host OS in accordance with the hardware allocation data.

Abstract: A plant monitoring device includes storage and one or more processors. The storage includes an alarm database in which a plurality of items of determination information as to alarm information is registrable, the alarm information being identification information for identifying an alarm. The processors are configured to register, in response to input of an item of determination information as to the alarm information, the item of determination information and the alarm information in the alarm database in association with each other.

Abstract: According to one embodiment, a distributed control system comprises a communication network and a plurality of control devices configured to control devices to be controlled, respectively. The control devices each include a simulator to which a program organization unit is allocated in advance, configured to simulate the allocated program organization unit, and a shared memory that stores a simulation result of the program organization unit simulated by the simulator to be shared with another control device. At least one of the control devices includes a simulation table database that can store therein an execution time of each of the program organization units allocated in advance to the control devices, and a simulation commander that stores, in the simulation table database, the execution time of each of the program organization units corresponding to the simulation result.

Abstract: According to one embodiment, a control server includes a storage that stores an object program, a know-how database and a weight database, and a processor. The processor determines a processing result of a first processing executed by the object having received an execution instruction is effective when a sum is equal to or larger than a certain threshold, the sum being a sum of weights for an identified client apparatus out of weights associated with an object ID of the object having received the execution instruction in the weight database.
