In addition to the functions of Unity Pro Extra Large, Unity Pro XLS provides
a set of specic verication and protection function blocks to facilitate the creation
and debugging of SIL 3 Quantum
™
projects.
For a description of these specications and their setup, as well as the functional
limitations provided for within the framework of SIL 3 certiable safety projects
according to IEC 61508 – refer to the document entitled “Quantum Safety PLC,
Safety Reference Manual” 01/2010, No. 3303879.03 – approved by TÜV Rheinland
and available at www.schneider-electric.com.
The Unity Pro XLS programming tool is certied compliant with the requirements of
IEC 61508 for managing SIL 3 applications with SIL 3 Quantum 140CPU65160S/
67160S PLCs.
It offers the complete range of functions required to program an SIL 3 project:
In-depth diagnostics b
Project protection b
During project creation, it is the selection of the Quantum processor that determines
whether or not the project created will be a safety project.
Unity Pro XLS is capable of processing the Unity Pro application types. No other
programming tool is needed on the computer.
To program a safety project, Unity Pro XLS provides two IEC 61131-3
programming languages:
Function Block Diagram (FBD) b
Ladder language (LD) b
Safety program structure
A safety project is programmed entirely in a master task (MAST).
It is not possible to:
Program FAST, TIMER, INTERRUPT or AUX tasks b
Use subroutines (SR sections) b
