The invention relates to a diagnostic system which involves the use of a piece of observed information () coming from a process () monitored by a programmable automaton (). The diagnostic system includes: an observation module () which collects, at input, the information observed () and delivers, at output, a piece of processed information () to a learning module (); and a detection module () which collects, at input, the observed information () in order to apply a detection process () thereto including a diagnostic function (), which comes from the learning module (), in order to deliver a diagnostic result () at output. The observation module () and the detection module () are executed by the processing unit () of the programmable automaton () in the form of function units in accordance with standard IEC1131-3. The learning module () elaborates the diagnostic function () using an algorithm based on neural networks or on fuzzy logic.

Predictive diagnostic system in a programmable automaton

A communication system for automation equipment on a TCP/IP network. The automation equipment controls an automation application by executing an application program written according to standard IEC1131-3. The communication system includes at least a reception WEB function block integrated into the application program to implement a WEB server function, and/or at least one send WEB function block integrated into the application program to implement a WEB client function, and an HTTP interface capable of routing messages between the TCP/IP network and WEB function blocks identified by a URL address. The contents of HTTP requests may be an XML frame or a UEL encoded frame.
