10.4 Software diagnostic messages
The device provides the following software diagnostic messages:
n DSP diagnostics
Diagnostic messages of the universal digital channels of the module (DXP 1, 3, 5, 7).
n IO-Link master diagnostics
The IO-Link master reports problems within the IO-Link communication.
n 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.

FCE The DTM Force Mode is activated, which means, the actual output values may no
match the ones defined and sent by the field bus.

The status word is mapped into the module's process data.
In EtherNet/IP™ the mapping can be deactivated via the Gateway Class (VSC 100).
NOTE
Activating or deactivating the status and control word modifies the process data
mapping.
Control word
