Abstract: A fault tolerant system includes a primary virtual machine that is formed on a primary machine in which a primary hypervisor runs, and is configured to input virtual interrupt based on an external interrupt from the primary hypervisor to a primary guest OS, and a secondary virtual machine that is formed on a secondary machine in which a secondary hypervisor runs, and is configured to input the virtual interrupt to a secondary guest OS on the basis of timing information on the virtual interrupt transmitted from the primary virtual machine. The primary virtual machine is configured to transmit the timing information on the virtual interrupt including the number of branch instructions executed by the primary guest OS before inputting the virtual interrupt, and including an execution suspension position when inputting the virtual interrupt to the secondary virtual machine.

Abstract: A control system includes at least one field device, a first control apparatus, a second control apparatus, a cache server, and a network. The first control apparatus has a first field device directly connected thereto and includes a first access route controller and a first control application capable of controlling the first field device. The second control apparatus includes a second access route controller and a second control application capable of controlling the first field device. The cache server includes a memory and a third access route controller. The first through third access route controllers are configured to work together to be capable of transferring, to the cache server, an input/output instruction for the first field device from the second control application.

Abstract: When a worker executes an operation on an actual plant, an information processing device generates a first calculation result obtained by calculating a behavior of the actual plant after execution of the operation using a virtual plant following an operational status of the actual plant and generates each second calculation result obtained by calculating a behavior of the actual plant with respect to each of operation pattern plans corresponding to a state of the actual plant. The information processing device evaluates the operation that is executed by the worker based on the first calculation result and the second calculation result.
