Preface
IMPORTANT
The extreme environment GuardLogix controller, catalog numbers
1756-L73SXT and 1756-L7SPXT, provides the same functionality as the
1756-L73S controller, but is designed to withstand temperatures of
-25...70 °C (-13...158 °F).
Logix-XT system components are rated for extreme environmental conditions
only when used properly with other Logix-XT system components. The use of
Logix-XT components with traditional Logix system components nullifies
extreme-environment ratings.
Studio 5000 Environment
The Studio 5000™ Engineering and Design Environment combines engineering
and design elements into a common environment. The first element in the Studio
5000 environment is the Logix Designer application. The Logix Designer
application is the rebranding of RSLogix™ 5000 software and will continue to be
the product to program Logix5000™ controllers for discrete, process, batch,
motion, safety, and drive-based solutions.
The Studio 5000 environment is the foundation for the future of Rockwell
Automation® engineering design tools and capabilities. It is the one place for
design engineers to develop all the elements of their control system.

Safety Application Requirements
The GuardLogix 5570 controller system is certified for use in safety applications
up to and including Safety Integrity Level (SIL) 3 and Performance Level (e) in
which the de-energized state is the safe state. Safety application requirements
include evaluating probability of failure rates (PFD and PFH), system
reaction-time settings, and functional-verification tests that fulfill SIL 3/PLe
criteria.
GuardLogix-based SIL 3/PLe safety applications require the use of at least one
safety network number (SNN) and a safety task signature. 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 Controller Systems Safety Reference Manual, publication
1756-RM099
operating a GuardLogix SIL 3, PLe safety system.
. You must read, understand, and fulfill these requirements prior to
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 CIP Safety device must also be
configured with the safety subnet’s SNN. The SNN can be assigned
automatically or manually.
For information on assigning the SNN, see Managing the Safety Network
Number (SNN) on page 43.
Rockwell Automation Publication 1756-UM022A-EN-P - November 2012 11
Chapter 1 System Overview
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 includes safety logic, data, and
configuration. The GuardLogix system uses the safety task signature to
determine the project’s integrity and to let you verify that the correct project is
downloaded to the target controller. Creating, recording, and verifying the safety
task signature is a mandatory part of the safety-application development process.
Distinguishing between Standard and Safety Components
See Generate a Safety Task Signature
Slots of a GuardLogix system chassis not used by the safety function may be
populated with other ControlLogix modules that are certified to the Low
Voltage and EMC Directives. Refer to http://
find the CE certificate for the Programmable Control–ControlLogix Product
Family and determine which modules are certified.
You must create and document a clear, logical, and visible distinction between the
safety and standard portions of the controller project. To aid in creating 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 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.
on page 96 for more information.

The ControlLogix Controllers User Manual, publication 1756-UM001
provides information on using ControlLogix devices in standard (non safety)
applications.
HMI Devices
HMI devices can be used with GuardLogix controllers. HMI devices can access
standard tags just as with a standard controller. However, HMI devices cannot
write to safety tags; safety tags are read-only for HMI devices.

3 GuardLogix controllers are integrated controllers with the ability to move (map) standard tag data into safety
tags for use within the safety task.
ATT EN TI ON : This data must not be used to directly control a SIL 3/PLe
output.
4 Controller-scoped safety tags can be read directly by standa rd logic.
5 Safety tags can be read or written by safety logic.
6 Safety tags can be exchanged between safety controllers over Ethernet or ControlNet networks, including 1756
and 1768 GuardLogix controllers.
7 Safety tag data, program- or controller-scoped, can be read by external devices, such as HMI devices, personal
computers, or other standard controllers.
Once this data is read, it is considered standard data, not SIL 3/PLe data.

Chapter 1 System Overview
Selecting System Hardware
The GuardLogix system supports SIL 3 and PLe safety applications. The
GuardLogix controller is made up of a primary controller and a safety partner
that function together in a 1oo2 architecture. Ta b l e 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 required for safety applications.

Instructions
1756-IN005
Extreme environment (XT) controllers require an XT power supply.
You can install or remove a controller while chassis power is on and the system is
operating.
WARNING: When you insert or remove the module while backplane
power is on, an electrical arc can occur. This could cause an explosion in
hazardous location installations.
Be sure that power is removed or the area is nonhazardous before
proceeding. Repeated electrical arcing causes excessive wear to contacts on
both the module and its mating connector. Worn contact may create
electrical resistance that can affect module operation.
The ESM begins charging when one of these actions occurs:
• The controller and ESM are installed into a powered chassis.
• Power is applied to the chassis that contains a controller with the ESM
installed.
• An ESM is installed into a powered controller.
After power is applied, the ESM charges for up to two minutes as indicated by
CHRG or ESM Charging on the status display.
1. Insert the key into the primary controller.
2. Turn the key to the PROG position.
The safety partner does not have a keyswitch.

Insert or Remove a Memory Card
After you have inserted the controller into the chassis, see Chapter 9
information on interpreting the status indicators on the primary controller
and safety partner.
WARNING: When you insert or remove the memory card when power is
on, an electrical arc can occur. This could cause an explosion in hazardous
location installations. Be sure that power is removed or the area is
nonhazardous before proceeding.
AT TE NT IO N: If you are not sure of the contents of the memory card,
before you install the card, turn the keyswitch of the controller to the
PROG position. Depending on the contents of the card, a power cycle or
fault could cause the card to load a different project or operating system
into the controller.
The controller ships with an SD card installed. We recommend that you leave an
SD card installed.

Make Communication Connections
The controller has a USB port that uses a Type B receptacle. The port is USB 2.0compatible and runs at 12 M.
To use the USB port of the controller, you must have RSLinx software, version
2.59 or later, installed on your workstation. Use a USB cable to connect your
workstation to the USB port. With this connection, you can upgrade firmware
and download programs to the controller directly from your workstation.
ATTENTION: The USB port is intended for temporary local programming
purposes only and not intended for permanent connection.
The USB cable must not exceed 3.0 m (9.84 ft) and must not contain hubs.
WARNING: Do not use the USB port in hazardous locations.
