Safety Application Development
Safety Concept Assumptions
The safety concept assumes the following requirements:
• If you are responsible to create, operate, and maintain the application,
you are fully qualified, specially trained, and experienced in safety
systems.
• You apply the logic correctly, meaning that programming errors can be
detected by strict adherence to specifications, programming, and
naming rules can detect programming errors.
• You perform a critical analysis of the application and use all possible
measures to detect a failure.
• You confirm all application downloads via a manual check of the safety
signature.
• You perform a complete functional test of the entire system before the
operational startup of a safety-related system. This test includes, but is
not limited to, the following:
– Validating the overall functionality of the implemented safety
functions, including I/O configuration performed by Add-On
Profiles (AOP), beyond the limits of the individual devices
(boundary testing).
– Verifying the correct versions of software are used.
