Diagnosis in the User Interface
Device tree
In online mode, the device tree allows for an exact pinpointing of a pending diagnosis.
Error flag (red triangle): Hard error, such as an incorrect/missing device or connection interruption.
Diagnosis flag (red exclamation mark): Indicates that a diagnosis entry is currently available for exactly this device.
Error-cleared flag (gray exclamation mark): Indicates that a previously pending error has been corrected.
Status Page
The status page of CAN bus displays the bus state, diagnostic messages, and the state of various parameters. On this page, you can check whether messages have been sent and received or lost. Moreover, you see whether the driver could be opened (Driver Instances > 0, Last Driver Open Error).
Logger Page
A filtered view of the PLC logger is displayed at both Controller level and Device level. This view shows only the entries that were created by the respective device.
