Configuring the Distributed I/O (DP)
How to find nodes in the topology view
In larger configurations you can locate a required node via the menu command
Options > Go To. The next dialog box "Go To" displays all nodes of the
PROFIBUS network:
1. Select the required node (e.g. a DP slave)
2. Click on the "Node" button to display the node in the center of the window.
Click on the "Diagnostic repeater" button to display the assigned in the center
of the window.
Display of the topology in tables
If you prefer to display the topology in a table rather than graphically, call menu
command View > Table > Topology.
Preparing line diagnostics
Use the same procedure as in HW Config or under NetPro. In the topology display,
call menu command PLC > Prepare Line Diagnostics.
Calling the module status
Use the same procedure as in HW Config or under NetPro. In the topology display,
call menu command PLC > Module Status.
How to save and open topology data
Select the menu command File > Save or File > Save As to save the current
display. This function allows to easily save the data you have acquired online for
the purpose of later diagnostics and error evaluation.
How to export topology data
You can use the following view to export topology data:
• The "Table" view (after calling menu command View > Table)
• The "Statistics" dialog box (after calling menu command PLC > Statistics)
• The "Diagnostics buffer" dialog box (after calling menu command PLC >
Diagnostics Buffer)
The CSV (ASCII) export format can be read and edited with other applications.
The topology display can no longer read exported data.
