Safety Routines
Safety routines have the same attributes of standard routines, except for the following:
- Safety routines can exist only in safety programs.
- Safety routines cannot read or write standard tags.
- Safety routines can only be done in Ladder Logic.
One safety routine must be designated as the main routine in each safety program. Another safety routine can be designated as the fault routine for that safety program.
Only safety-certified instructions or Add-on Instructions composed from them are used in safety routines. For a list of instructions, see Safety Instructions.
A watermark visually distinguishes a safety routine from a standard routine.
