Configuring the Distributed I/O (DP)
Example of Visual Presentation in the Dialog "Module Status"
If the functions of all segments to which the Diagnostic Repeater is connected are
free of error, the corresponding tabs in the dialog "Module Status" are displayed as
follows:
If a segment is switched off (that is, it is not possible to diagnose it), the following
symbol will appear at the side of the register title:
Symbol for a switched off segment
An error in segment "DP2" results in an error symbol at the side of the "DP2" tab
identifier. The remaining segments are free of error:
The "DP2" tab could show the disturbance in the following view: The Diagnostic
Repeater is assigned to PROFIBUS address 4, the error is located between the
partners assigned to the PROFIBUS addresses 16 and 21. In addition, the view
shows the distance to the neighboring DP Slaves.
In the figure below you can find an example of a simplified detailed presentation of
the arrangement illustrated above.
