Preface
This manual describes how to use FLEX 5000™ standard and safety I/O
modules in Logix 5000™ control systems.
Make sure that you are familiar with the following:
• Use of a controller in a Logix 5000 control system
• Use of an EtherNet/IP™ network, if the digital I/O modules are installed
in a remote location from the controller that is accessible via the
EtherNet/IP network
• Use of safety systems
• Studio 5000 Logix Designer® environment
Summary of Changes This manual was revised to add information about FLEX 5000 I/O safety
modules. This table indicates where new content exists in the manual.
Manual Conventions Within this manual, we simplified product names and added product icons for
your ease of use.
We us e standard module to indicate a module that does not have functional
safety capability. We use safety module to indicate a module with functional
safety capability (catalog numbers ending in “S” or “SXT”). Further, we use
FLEX 5000 I/O module to indicate when a concept or task applies to both the
standard and safety digital I/O modules.

Feature Support
Throughout this manual, graphics appear with section titles to indicate the
digital I/O modules that support the feature that is described in that section.
If both standard and safety modules support a feature, you see icons for both
types.
If only one type of module, standard or safety, supports a feature, you see only
one type of icon.

IMPORTANT You cannot use FLEX 5000™ I/O modules with all Logix 5000™ controllers.
For example, you can use FLEX 5000 I/O modules with CompactLogix™ 5380
and ControlLogix® 5580 controllers but not with CompactLogix 5370 and
ControlLogix 5570 controllers.
You can use FLEX 5000 I/O modules with Logix 5000 controllers as
remote I/O modules only.
Throughout this publication, the term Logix 5000 controller refers to the
controllers with which you can use FLEX 5000 I/O modules in a given
capacity. The term does not refer to all Logix 5000 controllers.
For the most current information on the Logix 5000 controllers with which
you can use FLEX 5000 I/O modules, see the product description
at http://www.ab.com.

Chapter 1 Digital I/O Module Operation in a Logix 5000 Control System
Logix 5000 controllers use FLEX 5000 standard and safety I/O modules to
control devices in a control system. The controllers access the modules over an
EtherNet/IP™ network. FLEX 5000 I/O modules use terminal base (TB)
assemblies to connect field-side wiring.
FLEX 5000 I/O modules use the Producer/Consumer network communication
model. This communication is an intelligent data exchange between modules and
other system devices in which each module produces data without first being
polled.
You use FLEX 5000 I/O modules as remote I/O modules that are accessible via
an EtherNet/IP network. The modules are installed to the right of a FLEX 5000
EtherNet/IP adapter.
Logix 5000 controllers can exchange data with the modules over the network.
Figure 1 shows a standard controller with standard I/O modules. Standard
controllers do not support safety I/O modules.

Digital I/O Module Operation in a Logix 5000 Control System Chapter 1
Figure 2 shows a safety controller with standard and safety I/O modules. Safety
controllers support both standard and safety I/O modules.
Figure 2 - FLEX 5000 Safety I/O Modules in a Logix 5000 Control System
Controller and Software
Compatibility
Controller and programming software compatibility requirements apply when
you use FLEX 5000 standard and safety I/O modules. A module type and how it
is used affect which requirements apply.
You must also consider Logix Designer application version requirements when
you design your system. For example, you can use FLEX 5000 safety I/O
modules with only version 32 or greater of the Logix Designer application.
Controller Compatibility
Compatibility between Logix 5000 controllers and FLEX 5000 I/O modules
varies based on module type, that is, whether the module is standard or safety.
While you must pair safety I/O with a safety controller, you can also pair
standard I/O with a safety controller. For example, ControlLogix 5580
controllers are compatible with FLEX 5000 standard I/O modules.
GuardLogix® 5580 controllers are compatible with FLEX 5000 standard and
safety I/O modules.

Secure Access to the System To secure access to the [device] by authorized users only, consider these options:
• Password helps protect the source and execution of the control program
• Remove the key from the controller
• Deploy EtherNet/IP devices in accordance with recommended
architectures and concepts. See the Converged Plantwide Ethernet
(CPwE) Design and Implementation Guide, publication ENET-TD001.
• Implement physical barriers, such as locked cabinets
To secure access to the system, consider these options:
• Follow industry best practices to harden your personal computers and
servers, including anti-virus/anti-malware and application whitelisting
solutions.
The recommendations are published at the Rockwell Automation
technical support center in Knowledgebase article Rockwell Automation
Customer Hardening Guidelines, #546987. The technical support center is
available at: https://rockwellautomation.custhelp.com/
• Develop and deploy backup and disaster recovery policies and procedures.
Test backups on a regular schedule.
• Minimize network exposure for all control system devices and systems, and
confirm that they are not accessible from the Internet.
• Locate control system networks and devices behind firewalls and isolate
them from the business network.
• Subscribe to the Rockwell Automation Security Advisory Index,
Knowledgebase article KB54102, so you have access to information about
security matters that affect Rockwell Automation products.
