Diagnosis history on the controller protocol

Logged diagnosis messages from the controller protocol can be read out on the “Diag History” tab. The diagnosis buffer operates as a ring buffer with a current maximum size of 1000 entries.

The possible errors are grouped into three types:

• Info: e.g. information on the connection establishment
• Warning: e.g. PROFINET diagnostic alarms
• Error: e.g. Loss of connection

“AddInfo” indicates whether additional information about the event is available. If this is marked by “Yes”, the additional information can be fetched and displayed by clicking on the respective message. In the case of a diagnosis alarm (“Diagnosis” appears), the precise diagnosis information can be fetched at the corresponding level (device, API or module).

The complete diagnosis buffer is cleared by pressing the “Clear Diag History” button.

The displayed messages can be saved in a .TXT file by pressing the “Export Diag History” button.
