8.3.6 Write output data of individual IO-Link ports
23016
Register area for separate access to output data of individual IO-Link ports: → Single Port Access
(→ p. 82)
The area contains the following data for each IO-Link port X01...X08:
 Digital output data at clamp 2
 Digital output data at clamp 4 (DO)
 IO-Link output data
► Observe the general rules for access to the Modbus registers (→ Rules for accessing the
Modbus register (→ p. 58))!
With one write command, several connected register areas of a IO-Link port can be written
(e. g. registers 1100 and 1101).
► 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
