Chapter 1
Product Overview
Product Description The Allen-Bradley® 42AF RightSight™ sensor with IO-Link features a new user
interface boosting ultra-bright status indicators, in an 18-mm base and nose
mount. Connecting the 42AF RightSight sensor to IO-Link allows you to take
advantage of advanced sensing functionality including real-time diagnostics,
Automatic Device Configuration (ADC) and access to multiple parameters.
Operation Modes The sensor can operate in two modes:
Standard IO (SIO) Mode: The sensor default-operation mode. The sensor
outputs and user interface behave as described in the installation instructions
included with the product. This mode of operation is active when the sensor is
connected to digital input devices such as a PLC inputs modules, distribution
boxes, and input terminal connections.
IO-Link Mode: This mode is automatically activated when the sensor is
connected to an IO-Link enabled master device. Upon entering this mode, the
green light-emitting diode (LED) on the sensor starts blinking at a rate of one
hertz to indicate that IO-Link communication has been successfully
established with the master. The sensor transmits more parameter and
diagnostic information that can be accessed via the PLC process data. No user
intervention is required to enable this functionality within the sensor.
Features • Right-angle housing with universal 30 mm (1.18 in.) threaded nose and
18mm (0.71 in.) threaded base for maximum application flexibility
• 360° highly visible (status indicators help the operators verify proper
operation regardless of sensor installation location)
• Visible status indicator light source for ease of alignment
• Alignment aid helps deliver reliable operating margin
• Dual auto PNP or NPN outputs for added application flexibility
• IP69K rated enclosure
• IO-Link 1.1 Communication protocol that is offered in all standard
modes

10 Rockwell Automation Publication 42AF-UM001A-EN-P - February 2019
Chapter 1 Product Overview
•IO-LinkFeatures:
– Sensor Heartbeat™ feature helps achieve excellent reliability
operation by indicating to the PLC if a sensor has lost connectivity
due to sensor failure or faulty wiring.
– Margin Low Alarm minimizes downtime by indicating when the
sensor is about to fail due to insufficient light being reflected.
– Signal Strength provides the raw measurement value of the amount
of light that reflects from the target.
– Margin Levels displays the excess gain above the sensor threshold to
help reliably detect the target.
– Contrast Levels display the difference between the light signal levels
that the sensor read the last time that the output was ON versus the
last time the output was OFF. The IO-Link parameter contrast levels
help identify enough difference between the target and the
background.
– Margin Low and High Indication Multipliers allow for specific
minimum margin levels when the local indication LED indicates
marginal conditions and stable conditions.
– Location Indication helps locate the sensors in large machines where
there are several units close to each other.
– Alignment Mode facilitates the alignment of the sensors in
applications where a transmitted beam receiver or a polarized
retroreflective sensor must be optimally aligned.
– Timers and Counters add additional sensor functionality by allowing
the operator to count the number of times a target has been detected.
– Timers and Counters add additional sensor functionality by allowing
the operator to count the number of times a target has been detected.
– Pin 2 Enable parameter allows continuous monitoring of the sensor
while providing access to a discrete output. Pin 2 Enable is ideal for
applications where high-speed sensor detection is critical to the
application.
– Process Data Maps allow for selection of the type of information that
is continuously sent to the PLC as a process data parameter.
– Temperature allows operators to visualize the internal temperature
value and to increase or decrease depending on the influence of the
ambient temperature on the internal sensor temperature.

Chapter 2 Installation
Alignment Indication The green LED can also serve as a set-up alignment aid, which indicates that a
margin of 1.5, has been reached. The indication means that the sensor is
receiving at least 1.5 times the signal strength back from the target that is
required to trigger an output signal. In general, it is desirable to have a higher
margin to help overcome any deteriorating environmental conditions, for
example, dust build-up on the sensor lens. When aligning the sensor, the
preferred performance can be obtained if this margin indicator is illuminated
with the target in place. When aligning diffuse mode sensors, be sure that the
sensitivity is set at its maximum setting (use the single-turn adjustment knob
on the front panel). Pan the sensor left, right, up, and down to center the beam
on the target. It could then be necessary to decrease this setting to help prevent
the sensor from detecting a background object. If this problem persists, the
application requires the use of a background suppression, sharp cutoff diffuse,
or retroreflective sensing mode.

Light-emitting diode Disable -For normal operation, the white wire needs no connection.
To disable the light source, connect the white wire to +V.
Frequency Select - For normal operation, the white wire needs no connection.
To change the emitter operating frequency, connect the black wire to +V. This feature is supported in future
firmware revisions of the Transmitted Beam Receiver.
IMPORTANT For Transmitted Beam Emitter only: Do not connect pin 2 and pin 4 for
normal operation. Unless a change in frequency is required when working
with a receiver, these two pins remain unconnected when wiring the
Transmitted Beam Emitter sensor to an Allen-Bradley® ArmorBlock® I/O
module.

42AF RightSight Sensor with IO-Link Overview
What Is IO-Link? The IO-Link technology is an open point-to-point communication standard
and was launched as (IS) IEC 61131-9. IO-Link is now the first globally
standardized technology for sensor and actuator communication with a field
bus system. This technology provides benefits to both OEMs and End Users.
IO-Link provides communications-capable sensors to the control level by a
cost-effective point-to-point connection. IO-Link provides a point-to-point
link between the I/O module and sensor that is used for transferring detailed
diagnostics, device identity information, process data, and parameterization.
IO-Link communication is based on a master-slave structure in which the
master controls the interface access to the sensor. The option of using the
intelligence that is integrated into the sensor provides the user with new
commissioning methods. Benefits range from reduced installation time during
startup to increased diagnostics over the lifetime of the machine. Benefits of
IO-Link technology include:
• Reduced inventory and operating costs
• Increased uptime/productivity
• Simplified design, installation, set up, and maintenance
• Enhanced flexibility and scalability
• Detailed diagnostic information for preventative maintenance
Why IO-Link? IO-Link Offers a Full Range of Advanced Features and Functions
Seamless Integration
• Forward and backward compatible, sensor catalog numbers remain the
same
• No special cables required
• Connectivity options remain the same

Chapter 3 42AF RightSight Sensor with IO-Link Overview
• Access IO-Link functionality by simply connecting an IO-Link enabled
device to an IO-Link master
• Analog devices no longer require a dedicated input card
Real-time Diagnostics and Trending
• Real-time monitoring of the entire machine down to the sensor level
• Optimized preventative maintenance—identify and correct issues
before failures can occur
• Detect sensor malfunctions/failure
Sensor Health Status
• Real-time monitoring helps confirm that sensors are operating correctly
• Detect damaged sensors and pinpoint their exact location for quick
troubleshooting through Application Specific Name parameter
Device Profiles and Automatic Device Configuration
• “Golden” device configurations are stored in the IO-Link master
module
• Multiple configurations can be stored in controller to support changes
in machine production, for example tool changes
• Within minutes instead of hours, modify sensor parameters to produce
different finished goods
Descriptive Tags
• Faster programming during initial setup
• More efficient troubleshooting process-data tags are named based on the
information they provide
• Easily monitor sensor data though intuitive tag names
