Abstract: A file obtained by converting event information into information in RSS or Atom format is held in a web server. The file is periodically read and displayed by using an RSS reader. A general web server and a general RSS reader can be used, and since HTTP is used, an existing security technique such as SSL can be used.

Abstract: Disclosed a control system 1 performing, through an HTTP communication, a communication between a client terminal 10 that remotely performs an operation instruction and a controller 20 related to a control/monitoring for an equipment, passing the instruction, which goes from the client terminal 10 to the controller 20, through a CGI message interpretation section 23, and outputting data such as monitoring information of the equipment, which goes from the controller 20 to the client terminal 10, as an XML message.

Abstract: An automatic layout method for performing an automatic layout of components on a diagram, the automatic layout method includes: generating a layout engine control object based on an operation of an application program; selecting at least one layout engine object from a plurality of layout engine objects for calculating coordinates of the components by different algorithms, at least one layout engine object being selected based on an instruction of the application program by the layout engine control object; and creating the diagram by the application program based on the coordinates calculated by the selected layout engine object.

Abstract: A node detection method and a node detector that enable selection of a node detection method in accordance with the structure and operation of a network are realized. A node detection method for detecting a node connected to a network comprises: a first step of interpreting a first script related to cycle to decide a detection cycle; a second step of interpreting a second script used for selecting information to select next information to be acquired, when node detection timing has come; a third step of gathering the selected information via the network by using a matching protocol; a fourth step of interpreting the acquired information and storing node information when it is judged that a new node has been detected; and a fifth step of causing all the nodes that have been detected by the last node detection, to perform the second to fourth steps.

Abstract: An electronic apparatus system has an electronic apparatus which transmits data through a communication network, a data control apparatus which is connected to the electronic apparatus through the communication network and stores data transmitted from the electronic apparatus, and a computer which enables to communicate with the data control apparatus, wherein the data control apparatus transmits the stored data to the computer.

Abstract: A production system wherein productagents are provided for products on a one-to-one basis and machine agent are provided for manufacturing equipment on a one-to-one basis, with the product agents and machine agents coordinating with each other to select a manufacturing equipment and cause manufacturing work to be done thereby; wherein the order of product manufacturing is changed depending on the priority of the product in the production system, with manufacturing work by a failed manufacturing equipment by suppressed, and another manufacturing equipment being substituted for the failed manufacturing equipment; wherein a precedence agent is provided that selects a manufacturing equipment ahead of a current manufacturing work and a backward agent is provided that remains backward and double manages working history along with the product agent; and wherein the machine agent manages depreciation information regarding the manufacturing equipment that the machine agent manages and measures the time the manufacturi
