Chapter 9 Kinetix 5700 Safe Torque-off Function
Safety Application Requirements
Safety application requirements include evaluating probability of failure rates
(PFH), system reaction time settings, and functional verification tests that
fulfill SIL 3 criteria. Refer to Average Frequency of a Dangerous Failure
on
page 285
for more PFH information.
Creating, recording, and verifying the safety signature is also a required part
of the safety application development process. Safety signatures are created by
the safety controller. The safety signature consists of an identification
number, date, and time that uniquely identifies the safety portion of a project.
This includes all safety logic, data, and safety I/O configuration.
For safety system requirements, including information on the safety network
number (SNN), verifying the safety signature, and functional verification tests
refer to the appropriate GuardLogix controller publication as defined in
Additional Resources
on page 13.
