Preface
Thoroughly read and understand this manual before installing and operating a
system using POINT Guard I/O™ modules.
Always observe the following guidelines when using a module, noting that in this
manual we use safety administrator to mean a person qualified, authorized, and
responsible to secure safety in the design, installation, operation, maintenance,
and disposal of the ‘machine’.
•Keep this manual in a safe place where personnel can refer to it when
necessary.
•Use the module properly according to the installation environment,
performance ratings, and functions of the machine.
See Understand Suitability for Use on page 15 and Safety Precautions on
page 17.
Product specifications and accessories can change at any time. Consult with your
Rockwell Automation representative to confirm specifications of purchased

Studio 5000 Environment The Studio 5000® Automation Engineering & Design Environment combines
engineering and design elements into a common environment. The first element
is the Studio 5000 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. The Studio 5000
environment is the one place for design engineers to develop all of the elements of
their control system.

Chapter 1
POINT Guard I/O Overview
Use the POINT Guard I/O safety modules in the POINT I/O platform to
distribute safety I/O on a safety-control network that meets the requirements up
to and including SIL CL3, and PLe, Cat. 4 as defined in IEC 61508, IEC 61511,
IEC 62061, and ISO 13849-1. POINT Guard I/O modules may be used with
1756 GuardLogix, 1768 Compact GuardLogix, or SmartGuard 600 controllers.
You can configure the modules for use on DeviceNet networks by using the
network configuration tool, RSNetWorx™ for DeviceNet software. For EtherNet
networks, use the GuardLogix programming tool, the Logix Designer
application.

POINT Guard I/O Overview Chapter 1
Safety Precautions Observe these precautions for proper use of POINT Guard I/O modules.
Installing and Replacing Modules
When cleaning modules, do not use the following:
•Thinner
•Benzene
•Acetone
POINT Guard I/O Modules in
CIP Safety Systems
POINT Guard I/O modules are used in the POINT I/O platform and
implement CIP Safety protocol extensions over EtherNet/IP and DeviceNet
networks to communicate safety messages. POINT Guard I/O modules connect
to EtherNet/IP or DeviceNet networks via these network adapters.
ATTENTION: As serious injury may occur due to loss of required safety function,
follow these safety precautions.
•Never use test outputs as safety outputs. Test outputs are not safety outputs.
•Do not use Ethernet, DeviceNet, or ControlNet standard I/O data or explicit
message data as safety data.
•Do not use LED status indicators on the I/O modules for safety operations.
•Do not connect loads beyond the rated value to the safety outputs.
•Apply properly specified voltages to the module. Applying inappropriate
voltages may cause the module to fail to perform it’s specified function, which
could lead to loss of safety functions or damage to the module.
•Wire the POINT Guard I/O modules properly following the wiring requirements
and guidelines in Wire Modules on page 58.
•Set unique network node addresses before connecting devices to the network.
•Perform testing to confirm that device wiring, configuration, and operation is
correct before starting system operation.
•Do not disassemble, repair, or modify the module. This may result in loss of
safety functions.
ATTENTION:
•Clear previous configuration data before connecting devices to the network or
connecting input or output power to the device.
•Configure the replacement device properly and confirm that it operates
correctly.
•After installation of the module, a safety administrator must confirm the
installation and conduct trial operation and maintenance.

Chapter 1 POINT Guard I/O Overview
Distributed I/O communication for safety I/O data is performed through safety
connections supporting CIP Safety over an EtherNet/IP or DeviceNet network.
Data processing is performed in the safety controller. The status and fault
diagnostics of POINT Guard I/O modules are monitored by a controller.
In addition to I/O state data, the modules include status data for monitoring I/O
faults within each circuit.
The configuration information of the modules can be protected by a password.
1734-IB8S Digital Input Module Features
•Safety digital inputs
–Safety devices, such as emergency stop push buttons, gate switches, and
safety light curtains, can be connected.
–Dual-channel mode evaluates consistency between two input signals
(channels), which allows use of the module for safety Category 3 and 4
and in applications rated up to and including Performance Level e/
SIL CL3.
–Single-channel mode evaluates one input signal (channel), which allows
use of the module for safety Category 2 and in applications rated up to
and including Performance Level d/SIL CL 2.
–You can configure a discrepancy time to control how long two channels
are allowed to be discrepant before a fault is declared.
–An external wiring short-circuit check is possible when inputs are wired
in combination with test outputs. The module must be wired in
combination with test outputs when this function is used.
–Independently adjustable on and off delays are available per channel.
•Test outputs (digital input modules only)
–Separate test outputs are provided for short-circuit detection of a safety
input (or inputs).
–Power (24V) can be supplied to devices, such as safety sensors.
–Test outputs can be configured as standard outputs.
–Specific test outputs can be used for broken-wire detection of a muting
lamp.
1734-OB8S Safety Digital Output Module Features
•Solid-state outputs
•Dual-channel mode provides redundant control by using two output
signals (channels), which allows use of the module for safety Category 3
and 4, and applications rated up to and including Performance Level e/
SIL CL3.
•Safety outputs can be pulse-tested to detect field wiring short circuits to
24V DC.
