9.3.5 Read input data of individual IO-Link ports
34466
Register area for separate access to input data of the individual IO-Link ports: →Single Port Access
(→ S. 98)
The area contains the following data for each IO-Link port X01...X04:
 Digital input data at pin 2 / pin 4 (DI)
 Status information of IO-Link port
 Diagnostic and status information of the connected IO-Link devices
 Input data IO-Link
Observe the general rules for access to the Modbus registers (→Rules for accessing the
Modbus registers (→ S. 73))!
The parameter "Invalid Data" indicates whether the read IO-Link input data is valid.
► Also read and evaluate the corresponding diagnostic information!
