This paper presents an automatic outputs generation based on XML description of intelligent instruments. This description uses the service based approach called INOMs. The XML representation of intelligent instruments enables three different outputs: user informations output in html format, supervisor information output, and source code output for selected field bus network target. The intelligent instrument model is briefly described and the area of interest consists in the automatic code generation. A basic example is presented in order to illustrate the different steps and to show the simplicity of the operational implementation.
