IO-Link Interface
7.1
Cyclic Process Data
The IO-Link interface can be used to receive or transfer process data. The
individual input and output data are listed below in tabular form.
7.1.1
Output Data
Direction of communication:
Electronic circuit breaker
→
IO-Link Master
The output data is 5 bytes. Some of these bytes are configurable and can be
customized:
•
1st byte
: This byte contains collective messages that are transmitted for all
channels.
•
2nd byte:
This byte is used as a confirmation byte to identify what data is
transmitted to the master in this cycle via configurable bytes 3 ... 5.
•
3rd byte … 5th byte:
Configurable data. This data can be selected
separately via acyclic commands or cyclically as a contiguous dataset.
