Develop Safety Applications
This chapter explains the components that make up a safety project and provides
information on using features that help protect safety application integrity, such
as the safety task signature and safety-locking.
For guidelines and requirements for developing and commissioning SIL 3 and
PLe safety applications, refer to the GuardLogix 5570 Controller Systems Safety
Reference Manual, publication
1756-RM099 .
The Safety Reference Manual addresses the following:
• Creating a detailed project specification
• Writing, documenting, and testing the application
• Generating the safety task signature to identify and protect the project
• Confirming the project by printing or displaying the uploaded project and
manually comparing the configurations, safety data, and safety program
logic
• Verifying the project through test cases, simulations, functional
verification tests, and an independent safety review, if required
• Locking the safety application
• Calculating system reaction time
