Programmable Automation Controllers offer versatile applicability with highly flexible sensing signals , multiplexing and conditioning through high power processors and global memory that can aggregate raw data . It assists the business units and management systems to make the correct decisions with high level precision and much reduced chances of making errors (Prismark , 39 , Edwin , 54 . 5 . Conclusion The need for higher efficiency in automation of the industrial systems has drastically increased with time owing to the demands for higher and efficient...

It scales the special engineering requirements against the SILs . This part is largely aimed at developers of operating systems for safety-certified controllers . The third part is abut systematic failures and no quantitative prediction is involved . The tables in the part 3 indicate the applicability and need for various techniques at each of the SILs . Some of the material is in the form of annexes which are informative . Part 4 : Definitions and Abbreviations The fourth part of the IEC 61508 standard...
