Safety Programs
A safety program has the attributes of a standard program, except that it can be scheduled
only in the safety task.
- A safety program can also define program-scoped safety tags.
- A safety program can be scheduled or unscheduled.
- A safety program can contain only safety components.
- All routines in a safety program are safety routines. One safety routine must be designated as the main routine, and another safety routine can be designated as the fault routine.
- A safety program cannot contain standard routines or standard tags.
- Parameter connections between standard and safety tags are typically not allowed, except for a few limited exceptional cases.
