Safety Add-On Instructions
With RSLogix 5000® software, version 18 and later, you can create safety Add-
On Instructions. Safety Add-On Instructions let you encapsulate commonly-
used safety logic into a single instruction, making it modular and easier to reuse.
Safety Add-On Instructions use the instruction signature of high-integrity Add-
On Instructions and also a SIL 3 safety instruction signature for use in safety-
related functions up to and including SIL 3.
Creating and Using a Safety
Add-On Instruction
The flowchart on page 76 shows the steps required for creating a safety Add-On
Instruction and then using that instruction in a SIL 3 safety application program.
The shaded items are steps unique to Add-On Instructions. The items in bold
text are explained in the pages following the flowchart.
