An energy management system, provided with: a collector that collects information regarding energy efficiency of a production apparatus and a processor that performs at least one of monitoring, simulation, and optimization of energy efficiency in production activity performed by the production apparatus, on the basis of the information regarding energy efficiency collected by the collector, using a modeling unit in which information regarding energy efficiency of a constituent element of the production apparatus is modeled on the basis of a predefined rule.

Energy management system, energy management method, and program

An apparatus in a distributed control system having a network interface and wireless gateway coupled to the network interface. The network interface is configured to communicate with a network. The wireless gateway includes a wireless gateway function block application process configured to map process information between a wireless network having at least one wireless field device and the network. The wireless gateway further includes a wireless network management component configured to manage access to the wireless network and at least one wireless field device function block application process configured to define a resource and input and output process information of the wireless field device.

Block-orientated control system having wireless gateway for communication with wireless field devices

A communication control system is provided that performs communications satisfying a request for industrial applications and a request for open protocol communications at the same time. To this end, in the invention, a high-priority communication section performing critical communications to provide real time property and reliability, and a low-priority communication section performing communications based on an open standard protocol coexist in a same communication station.

Communication control system

A communication control system is provided that satisfies the needs of industrial applications in terms of real time properties, scalability and flexibility. For this purpose, the invention causes a communication station performing communications in accordance with a standard protocol to perform multiplex communications based on time division of a communication band. Communication is performed by dividing a communication cycle into time slots, and assigning a set of communication stations and a type of a communication section to each of the time slots.

A signal relay device, a communication network system and an operation system include: a standardized logic interface conversion unit for judging a control system type or a device type and converting a signal to a signal appropriate for a communication network; or a device side logic interface conversion unit for converting a signal from the communication network to a signal appropriate for the control system type or the device type. An operation monitoring station includes a an advanced control block for the control system or the device and transmits a control signal to the communication network.
