Automation technology in the industry takes an increasingly dominant position due to automation of processes, an area whose importance is constantly rising. This happens in everyday applications in production and in the instruction. Today, automation technology is almost always linked to the drive technology, control and information technology. Due to the rapid development of technology and micro computers, automation technology has become the most innovative and highest life of electrotechnology. This is to add the new industrial solutions, such as decentralization and visualization, require new systems of instruction. Moreover, through the standard IEC1131-3, valid worldwide, the discrepancy was eliminated in software products, which hitherto depended particular manufacturer. (more...)
