USING LOGIC PROGRAMMING FOR IMPROVE AND INCREASE THE RELIABILITY OF TOOLS AND EMBEDDED MACHINE TO AVOID SOME 'MISSION CRITICAL? IN FLEXIBLE MANUFACTURING LINES

摘要

The management of automation systems, including control system for tools machines can be done in three ways: -logical wired -logic programming -and mixed, both of them, wired and logical programming Nowadays, we still use in manufacturing lines logical wired, automation made by using relays and contactors. In this way the reliability is very low and leads to a high rate of defects and therefore breaks the functionality of the entire manufacturing process, sometimes with significant losses in productions. This entire possible problem can lead to "mission critical" situations in the manufacturing lines. In this paper we try to design some solutions to grow the reliability of flexible manufacturing lines by using microcontroller, PLC - Programmable Logic Controller and other embedded tools.
