8.3.4 Read input data of individual IO-Link ports
23072
Register area for separate access to input data of the individual IO-Link ports: → Single Port Access
(→ p. 82)
The area contains the following data for each IO-Link port X01...X08:
 Digital input data at clamp 2 / clamp 4 (DI)
 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
register (→ p. 58))!
The parameter "Invalid Data" indicates whether the read IO-Link input data is valid.
► Also read and evaluate the corresponding diagnostic information!
