Process data
The "Base" transmits 4 bytes of input via the IO-Link. The first ten represent the data of
the IO-Link device connected to the "Remote", while the 4th byte contains status
information. If an IO-Link device that outputs less than 4 bytes of input data is connected
to the "Remote", the remaining, unused bytes are transmitted with "0".
