EC: Allen-Bradley GuardLogix 5572S, 5573S PACs
Safety - Machine safety: Allen-Bradley GuardLogix programmable automation controllers are designed to provide OEMs and manufacturers with integrated safety, motion, discrete and drive control capabilities in one controller, while executing SIL2 and SIL3 safety functions. This is a Control Engineering 2013 Engineers' Choice Award winner.
The Allen-Bradley GuardLogix controller provides the same automation capabilities as the Allen-Bradley ControlLogix platform, plus safety-rated control for safety-related functions up to and including SIL3, PLe CAT IV. With one software program managing safety and standard functionality, engineers no longer need to manually manage the separation of standard and safety memory or worry about partitioning logic to isolate safety. This can also eliminate the need to write and coordinate multiple programs on different controllers, which in turn can reduce training and support costs.
In addition, one development environment helps eliminate expensive redevelopment. For example, if a control engineer needs to scale from one line to three, it’s as simple as porting the necessary application from one to the next. Fewer components also mean smaller panel enclosures, saving money on control cabinets and floor space. The integration of safety and standard control systems also provides operators and maintenance personnel with visibility to all machine events, including safety events, via the human-machine interface.
With the knowledge provided by the integrated system, personnel can respond quickly to return the machine to full production. The controller further benefits from the introduction of the Point Guard I/O SIL3 analog input module designed to provide automation and safety functionality in the Point I/O system. Users can apply the Point Guard I/O analog input module to measure temperature, pressure, and flow rate for analog safety functions.
