● What are the right steps to develop a safety program?
You have to refer to ISO 13849-1 and IEC 62061 guidelines for machine safety application
development and to IEC 61511 for process safety application development.
● Is it allowed to use FOR loops as an alternative for IF and CASE for boundary checks
in arrays?
No, it is not allowed to use it as an alternative.
If arrays are used in FOR loops, the programmer must still implement boundary checks.
