Andrew Parr's Programmable Controllers provides a thoroughly practical introduction to the use of PLCs in industry, covering programming techniques alongside systems-level design issues. In the third edition a masterclass series of real-world case studies have been added to illustrate typical engineering challenges - and model solutions.New material also includes the new IEC-61508 functional safety standard, use of Windows-based software on programming terminals, an expanded section on Scada, and extended coverage of networks and fieldbus.Andrew Parr works at ASW Sheerne
