Applications 
IO-Link can be used in the following applications: 
●  Simple connection of complex sensors/actuators with a large number of parameters to 
the control. 
●  Optimum replacement of IO-Link modules for sensor/actuator boxes when connecting 
binary sensors. 
In both cases, all diagnostics data is transmitted to the higher-level control via IO-Link. 
Parameter settings can be changed during operation. A sensor/actuator can be replaced 
without a programming device/PC thanks to the central data storage feature. 
The IO-Link range comprises: 
●  IO-Link master 
●  IO-Link module K20 
●  IO-Link starting controls 
●  IO-Link switching controls 
●  IO-Link sensors
