42EF RightSight Sensor with
IO-Link Overview
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
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
• 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
