Processes of creation For creation of the project had been effected research in the automation areas and software so that the hardware item were identified to which and software would be necessary. The chosen CLP was of the Beckhoff mark. Pioneering company in the supply of technology for automation using a PC or one notebook to twirl its programs. This is allowed on account of the software of programming of language of the called CLP of Twincat PLC.
Twincat PLC allows to work in up to 6 (six) programming languages, amongst them the language of text structuralized used in this project. For supervisory software, a system in the Visual platform Studio was projected that is developed by Microsoft. The Studio Appearance is a tool that allows the elaboration of graphical elements in a screen and that toward ours in case that, it can be come back toward a supervision line, since that adequately programmed. The Studio Appearance allows programming in languages as visual beginner’s all-purpose symbolic instruction code, C#, Java Script, htm and Ajax. Moreover, the Studio Appearance allows the use of the SQL Server. This tool is capable to store information in a data base. The SQL Server supports until 4GB of information. Until 4GB its use is gratis.
Then, to effect the screens of the supervisory one were used language HTML. To allow that the screens were remained brought up to date, the Ajax was used. Link for command buttons (addressing) was gotten by means of C#. The data base is addressed to the SQL Server. 5. Costs and benefits Below are cited values of market of the preventive maintenance and the necessity of purchase of an equipment. These data of table 1 are referring to an electric generator of 12KW supplied by the Thales, a French manufacturer. Stop process
