IO-Link device diagnostics
The device diagnostics map the IO-Link Event Codes (according to the IO-Link specification)
sent from the IO-Link devices to the diagnostic telegram of the master.
Event Codes can be read from the connected devices by using appropriate device tools (e.g.
IODD-Interpreter).
Further information concerning the IO-Link Event Codes and their meaning can be found in
the IO-Link specification or in the documentation of the connected devices.
