    Diagnosis in the User Interface

    Device tree

    In online mode, the device tree allows for an exact pinpointing of a pending diagnosis.

    • The error flag (red symbol) indicates a hard error, such as an incorrect/missing module or connection termination.

    • The diagnosis flag (red exclamation mark) of the respective module indicates that a diagnosis entry is currently available for exactly this device.

    • The error-cleared flag indicates that a previously pending error has been corrected.

    Device Status

    The Status tab displays the diagnostic data of the device.

    Logger

    A filtered view of the PLC logger is displayed at the Device level. This shows only the entries that were created by the respective device.
