System Overview
Safety Application
Requirements
The GuardLogix® 5570 controller system is certified for use in safety
applications up to and including Safety Integrity Level Claim Limit (SIL CL)
3 and Performance Level (e) where the de-energized state is the safe state.
Safety application requirements include probability of failure rates evaluation,
such as:
• Probability of failure on demand (PFD)
• Probability of failure per hour (PFH)
• System reaction-time settings
• Functional-verification tests that fulfill SIL 3/PLe criteria
GuardLogix-based SIL 3/PLe safety applications require at least one safety
network number (SNN) and a safety task signature be used. Both affect
controller and I/O configuration and network communication.
For SIL 3 and PLe safety system requirements, including functional validation
test intervals, system reaction time, and PFD/PFH calculations, refer to the
GuardLogix 5570 and Compact GuardLogix 5370 Controller Systems Safety
Reference Manual, publication 1756-RM099. You must read, understand, and
fulfill these requirements before you operate a GuardLogix SIL 3, PLe safety
system.

Chapter 1 System Overview
Safety Network Number
The safety network number (SNN) must be a unique number that identifies
safety subnets. Each safety subnet that the controller uses for safety
communication must have a unique SNN. Each safety I/O device must also be
configured with the SNN of the safety subnet. The SNN can be assigned
automatically or manually.
For information on how to assign the SNN, see Manage the Safety Network
Number (SNN) on page 57.
Safety Task Signature
The safety task signature consists of an ID number, date, and time that
uniquely identifies the safety portion of a project. This signature includes
safety logic, data, and configuration. The GuardLogix system uses the safety
task signature to determine project integrity and to let you verify that the
correct project is downloaded to the target controller. The ability to create,
record, and verify the safety task signature is a mandatory part of the safety-
application development process.
See Generate a Safety Task Signature on page 120 for more information.
Distinguish between
Standard and Safety
Components
Slots of a GuardLogix system chassis that are not used by the safety function
can be populated with other ControlLogix® modules that are certified to the
Low Voltage and EMC Directives. See
http://www.rockwellautomation.com/
rockwellautomation/certification/ce.page to find the CE certificate for the
Programmable Control>ControlLogix Product Family and determine the
modules that are certified.
You must create and document a clear, logical, and visible distinction between
the safety and standard portions of the controller project. As part of this
distinction, the Logix Designer application features safety identification icons
to identify the safety task, safety programs, safety routines, and safety
components. In addition, the Logix Designer application uses a safety class
attribute that is visible whenever safety task, safety programs, safety routine,
safety tag, or safety Add-On Instruction properties are displayed.
The controller does not allow writes to safety tag data from external human
machine interface (HMI) devices or via message instructions from peer
controllers. The Logix Designer application can write safety tags when the
GuardLogix controller is safety-unlocked, does not have a safety task signature,
and is operating without safety faults.
The ControlLogix Controllers User Manual, publication 1756-UM001,
provides information on using ControlLogix devices in standard (nonsafety)
applications.

HMI Devices
HMI devices can be used with GuardLogix controllers. HMI devices can
access standard tags as with a standard controller. However, HMI devices
cannot write to safety tags; safety tags are read-only for HMI devices.
Controller Data-flow
Capabilities
This illustration explains the standard and safety data-flow capabilities of the
GuardLogix controller.
Figure 1 - Data-flow Capabilities
No. Description
1Standard tags and logic behave the same way that they do in the standard Logix platform.
2Standard tag data, program- or controller-scoped, can be exchanged with external HMI devices, personal
computers, and other controllers.
3GuardLogix controllers are integrated controllers with the ability to move (map) standard tag data into
safety tags for use within the safety task.
ATTENTION: These data must not be used to control a SIL 3/PLe output
directly.
4Controller-scoped safety tags can be read directly by standard logic.
5Safety tags can be read or written by safety logic.
6Safety tags can be exchanged between safety controllers over Ethernet or ControlNet™ networks, including
1756 and 1768 GuardLogix controllers.
7Safety tag data, program- or controller-scoped, can be read by external devices, such as HMI devices,
personal computers, or other standard controllers.
IMPORTANT Once this data is read, it is considered standard data, not SIL 3/PLe data.

Chapter 1 System Overview
Select System Hardware The GuardLogix system supports SIL 3 and PLe safety applications. The
GuardLogix controller is composed of a primary controller and a safety partner
that function together in a 1oo2 architecture. Table 4 lists catalog numbers for
primary controllers and safety partners.
The safety partner must be installed in the slot immediately to the right of the
primary controller. The firmware major and minor revisions of the primary
controller and safety partner must match exactly to establish the control
partnership that is required for safety applications.
Primary Controller
The primary controller is the processor that performs standard and safety
functions and communicates with the safety partner for safety-related
functions in the GuardLogix control system. Standard functions include the
following:
• I/O control
•Logic
•Timing
• Counting
• Report generation
• Communication
• Arithmetic computations
• Data file manipulation
The primary controller consists of a central processor, I/O interface, and
memory.

System Overview Chapter 1
A three-position key switch on the front of the primary controller governs the
controller operational modes. The following modes are available:
•RUN
•PROGram
• REMote–this software-enabled mode can be Program, Run, or Test
Figure 2 - Key Switch Positions
Safety Partner
The safety partner is a coprocessor that provides an isolated second channel
(redundancy) for safety-related functions in the system.
The safety partner does not have a key switch or communication port. Its
configuration and operation are controlled by the primary controller.
Chassis
The ControlLogix chassis provides physical connections between modules and
the GuardLogix controller.
Power Supply
The ControlLogix power supplies listed on page 26 are suitable for use in SIL 3
applications. No extra configuration or wiring is required for SIL 3 operation
of the power supplies.
Select Safety I/O Device Safety input and output devices, like sensors and actuators, can be connected to
safety I/O on DeviceNet™ or EtherNet/IP™ networks. This connection
controls output devices by a GuardLogix controller system via DeviceNet or
EtherNet/IP communication.
