Abstract: The present invention relates to a system for accessing a programmable automatism unit (10) based on a WAP architecture, from at least a standalone communicating mobile device (40), such as a portable telephone, which integrates a navigator (41) complying with WAP architecture. This system includes a Web server (20), embedded in a piece of automatism equipment of the automatism unit (10), capable of generating static or dynamic informative data according to the WML language, and a network interface (30), connected to the Web server (20) through a network (25) of the Internet type, which authorizes access to said informative data from a WAP navigator (41) of a mobile device (40) communicating through a wireless network (35), in such a way that a user of such a WAP navigator (41) may access functions for monitoring, viewing and controlling the automatism unit (10).

Abstract: The invention concerns a method for reserving isochronous resources on a wireless network of the Hiperlan 2 type for connection set-up, said network comprising an isochronous resource manager, said method comprising the steps of: identification of a talker de vice and a listener device by a connection controller, acquisition by the isochronous resource manager of the list of the devices to be part of the connection; determination of the bandwidth required for connecting the talker and the listener by the isochronous resource manager, as a function of the list of devices to be part of the connection; set-up of a multicast group including the talker device and the listener device if said bandwidth is available.

Abstract: This invention relates to a communication system for automation equipment (10) on a TCP/IP network (50). The automation equipment (10) controls an automation application by executing an application program (20) written according to standard IEC1131-3. The communication system comprises at least a reception WEB function block (21) integrated into the application program (20) to implement a WEB server function and/or at least one send WEB function block (22) integrated into the application program (20) to implement a WEB client function and an HTTP interface (15) capable of routing messages between the TCP/IP network (50) and WEB function blocks identified by a URL address. The contents of HTTP requests may be an XML frame or a URL encoded frame.

Abstract: The present invention relates to an access system between an item of server automatic control equipment (20), which integrates transmission/reception means (25) to transmit and receive messages on a wireless proximity network (30) using a radio wave technology in compliance with the Bluetooth protocol, and at least one mobile device (10) or at least one item of client automatic control equipment (20′). An item of server automatic control equipment (20) comprises server communication means (27) to implement a link mechanism in order to supply control, display and monitoring functions of the server automatic control equipment from a mobile device or an item of client automatic control equipment.
