2.1 Advantages of IO-Link
The IO-Link system offers significant advantages as digital interface when connecting
sensors/actuators:
● Open standard in accordance with IEC 61131-9
–
Devices can be integrated in the same way in all conventional fieldbus systems and
automation systems
● Tool supported parameter setting and central data management
–
Fast configuration and commissioning
– Simple creation of current plant documentation even for sensors/actuators
● Single, uniform wiring and far fewer different interfaces at the sensors/actors
–
Standardized, uniform interface for sensors and actuators independent of their
complexity (switching, measuring, multi-channel, binary, mixed signals, etc.)
– Reduction in the variety of types and inventory
– Fast commissioning
– Any combination of IO-Link devices and sensors/actuators without IO-Link at IO-Link
master
● Continuous communication between sensors/actuators and the CPU
–
Access to all process data, diagnostic data and device information
– Access to device-specific data, such as energy data
– Remote diagnostics can be performed
● Continuous diagnostic information down to sensor/actuator level
–
Reduction in troubleshooting effort
– Minimizing risk of failure
– Preventive maintenance and optimization of service and maintenance planning
● Dynamic change of sensor/actuators parameters by the controller or the operator at the
HMI
–
Reduction in downtimes during product change
– Increased variability of the machine
● Automatic reassignment of parameters when devices are replaced during operation
–
Minimization of downtimes
– Device replacement by untrained personnel without additional aids
– Avoidance of incorrect settings
● Integrated device identification
–
Identification of the installed devices
– Ensure quality of result in production and manufacturing when replacing the device
