State of the IO-Link Ports
There is a status byte for each IO-Link port. You can find the status bytes at the following locations:
- In the process data object “DeviceState Inputs”
- In the CoE object 0xF100
The meaning of the status byte is displayed in the TwinCAT System Manager in the “Comment” field of the “Variable” tab (see following figure).
Please also note the information on the addition of the values in case of simultaneously occurring diagnosis messages in the PDO assignment chapter.
