>
9.3.4 Read input data of several IO-Link ports
34465
Register area for compact access to the input data of the IO-Link ports X01…X04: →Input Data
(→ S. 93)
The area contains the following data:
 Combined digital inputs - pin 2 / pin 4 (DI)
 Status information of the IO-Link ports
 Status information of the IO-Link devices
 Combined IO-Link input data
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 status information in addition to the input data
of the ports!
