9.3.7 Write output data of individual IO-Link ports
34452
Register area for separate access to output data of individual IO-Link ports: →Single Port Access
(→ S. 98)
The area contains the following data for each IO-Link port X01...X04:
 Digital output data at pin 4 (DO)
 IO-Link output data
► Observe the general rules for access to the Modbus registers (→Rules for accessing the
Modbus registers (→ S. 73))!
If the user tries to write more than 34 bytes of output data to a single port, the IO-Link master
cancels the execution of the command and returns the error code "2 ILLIGEAL ADDRESS".
► When writing outputs, ensure that the length of the transferred output data corresponds
with the configured process data length.
The output data is invalid in the following situations:
 No Ethernet cable connected
 PLC has terminated the connection
 Connection to the PLC has a timeout
