POINT Guard I/O Overview
Chapter 1
Safety Application
Requirements
POINT Guard I/O modules are certified for use in safety applications up to and
including Performance Level e (PLe/Cat. 4) and Safety Integrity Level 3
(SIL CL3) in which the de-energized state is the safe state. Safety application
requirements include evaluating probability of failure rates (PFD and PFH),
system reaction time settings, and functional verification tests that fulfill SIL 3
criteria.
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, functional verification test
intervals, system reaction time, and PFD/PFH calculations, refer to the following
publications.
You must read, understand, and fulfill the requirements detailed in these
publications prior to operating a safety system that uses POINT Guard I/O
modules.
