Rockwell Automation Publication IASIMP-QS005H-EN-P - April 2016 13
Chapter 1
Risk Assessment and System Design
Introduction
The GuardLogix® controller offers you the capability to integrate safety and standard control in the same system. Safety
functions supported by the system include:
• Determine specifically which gate has been opened or E-stop device has been pressed
• Perimeter and point-of-operation guarding
•Zone control
In this chapter, you learn the fundamentals of safety strategy development, see examples of risk assessment and estimation
worksheets and safety system design, and learn how Rockwell Automation can help.
In subsequent chapters of this toolkit, you’ll create a bill of materials based on the functional requirements identified by a
risk assessment. Once you’ve determined which safety components you’ll need, you’ll learn how to use the Safety
Accelerator Toolkit to layout your system wiring, integrate logic routines in your safety application program, and use
faceplates designed to facilitate HMI.
Before You Begin
Become familiar with the local, national, and international standards, including consensus standards that govern machine
safety.
The safety standards that would be applied for safeguarding a work cell, like the example shown in this quick start, are
extensive.
• National Standards • Risk Assessment Standards • Robotic Standards
• Safeguarding Application Standards • Controller Application Standards • Electrical System Design Standards
• Personal Protective Equipment Standards • Standards pertaining to Awareness Means • Energy Isolation Standards for Maintenance Tasks
• Energy Isolation Standards for Routine, Repetitive
And Routine Tasks
• Standards relating to validation and maintenance
associated with the verification of the system performance
on a regular basis
