New safety PLC
14 October 2013
ABB has launched a new safety PLC which offers flexible and powerful programming facilities that speed and simplify the development of safe control solutions for complex control applications.
The safety PLC – the AC500-S – is a new addition to ABB's established AC500 PLC range and features a dual processor architecture that complies with SIL3/PL e functional safety levels. Prior to commercial release, the new controller has been extensively field tested over three years in some 10 pilot applications including cranes, mining hoists, automatic guided vehicles, and robotics.
The AC500-S includes support for Structured Text (ST) programming - in addition to conventional graphical function block diagram (FBD) and ladder diagram (LD) software. This provides users with a high level programming approach that can greatly simplify the development of solutions for sophisticated applications requiring complex algorithms and mathematics.
