Configuring the Distributed I/O (DP)
If STEP 7 does not localize the error in segment "DP2" or if, for example, this
segment contains more than 32 partners and the Diagnostic Repeater cannot
operate correctly anymore, you are shown the following image:
Summary of all Symbols
The symbols o the registers can be of the following forms:
No segment error
Segment error
Segment is switched off
Information cannot be retrieved from the segment
3.11.2 Displaying the Topology With the Help of Diagnostic Repeaters
As of STEP 7 V5.2, in combination with a PROFIBUS configuration with Class 2
diagnostic repeaters 972-0AB01 it is not only possible to perform line diagnostics,
but also to display the PROFIBUS DP network topology.
In contrast to the network view under NetPro, this function does not display the
"Logic" view of a PROFIBUS subnet, but rather the physical arrangement of the
PROFIBUS nodes in their actual order as well as the distances to the nodes -
provide the diagnostic repeater was able to determine these data. The actual
nodes are displayed same as under NetPro.
