Designing Add-On Instructions
An Add-On-Instruction can be used across multiple projects. You can define the
instructions, the instructions can be provided to you by someone else, or they can
be copied from another project.
Once defined in a project, they behave similarly to the built-in instructions already
available in the Logix Designer application. They appear on the instruction
toolbar and in the instruction browser for easy access, just like built-in Logix
Designer application instructions.
Like standard 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. In addition to the instruction signature used for
high-integrity Add-On Instructions, safety Add-On Instructions feature a SIL 3
safety instruction signature for use in safety-related functions up to and including
SIL 3.
Refer to th
publication
for details on certifying safety Add-On Instructions and using them
in SIL 3 safety applications.
Add-On Instructions are made up of the following parts.
General information
The General tab contains the information you enter when you first create the
instruction. You can use this tab to update that information. The description,
revision, revision note, and vendor information is copied into the custom help for
the instruction. The revision is not automatically managed by the software. You
are responsible for defining how it is used and when it is updated.
