11.2.3 EXT_DIAG_OVERFLOW

This bit is set if more diagnostics data is present than will fit in the available diagnostics data area. For example, more channel diagnostics could be present than the send buffer or the receive buffer makes possible.

11.3 Diagnostics Processing from the System View

Inasmuch as it is bus-specific, the diagnostics information of the slaves is managed solely by the master interface (for example, IM308B).

All diagnostics from the application are made available to the S6 program via corresponding data bytes. If the External Diagnostics bit is set, the slaves to be diagnosed can already be evaluated in the diagnostics overview. Then, a special error routine can be called up, whereby the standard diagnostics information and the user-specific information can be evaluated.

After eliminating the current diagnostics situation, this can be signalled as a status message from the slave without setting the external diagnostics bit.

With the COM ET200, a comfortable diagnostics tool is available on-line. At the present time, identification- related diagnostics information can be displayed with it in plain text. In later phases, channel-related diagnostics will also be supported. User-specific diagnostics are only displayed if the EXT_DIAG bit is set.

In the type file for the COM ET200 and in the GSD [device master data] file, fields are already provided for referencing device-specific bits and pertinent plain text messages (for example, Bit 7: „I have had t;i good night!“).
