13.3.1.11 Notification of Input Data Invalidity
Input Invalid Flag is used to determine whether the process input data in the upper device is invalid for the IO-Link
communication or not.
Whether the input data is invalid or not can be monitored by Port1 – 4(IO-Link Process Data) Input Invalid Flag of the
Normal Exchange Area section. If the flag is 1, then the input data is invalid. If it is 0, the input data is valid.
See the example in the following figure.
The mapped register for Port1 – 4(IO-Link Process Data) Input Invalid Flag is D29028 and for the input invalid flag,
D29028.0~ D29028.3 correspond to Port 1~Port 4 respectively as shown in the following table.
