Displaying Maintenance Information
As of STEP 7 V5.4 Service Pack 1, certain PROFINET components can display information
indicating whether or not preventive maintenance is necessary and, if it is, how urgent it is.
The following maintenance information is available:
• Maintenance required (indicated by a green wrench):
The relevant component must be replaced within a foreseeable period.
• Maintenance demanded (indicated by an yellow wrench):
The relevant component must be replaced soon.
One example of maintenance might be the replacement of a fiber-optic cable due to increasing
attenuation on a port of the PROFINET interface.
How to Locate Faults
1. Open the online window for the project with the menu command View > Online.
2. Open all the stations so that the programmable modules configured in them are visible.
3. Check to see which CPU is displaying a diagnostics symbol indicating an error or fault. You
can open the help page with an explanation of the diagnostics symbols using the F1 key.
4. Select the station that you want to examine.
5. Select the menu command PLC > Diagnostics/Settings > Module Information… to display
the module information for the CPU in this station.
6. Select the menu command PLC > Diagnostics/Settings > Hardware Diagnostics to display
the "quick view" with the CPU and the failed
modules in this station. The display of the quick
view is set as default (menu command Option > Customize, "View" tab).
7. Select a faulty module in the quick view.
8. Click the "Module Information" button to obtain the information on this module.
9. Click the "Open Station Online" button in the quick view to display the diagnostic view. The
diagnostic view contains all
the modules in the station in their slot order.
10. Double-click a module in the diagnostic view in order to display its module information. In this
way, you can also obtain information for those modules that are not faulty and therefore not
displayed in the quick view.
You do not necessarily have to carry out all of the steps; you can stop as soon as you have
obtained the diagnostic information you require.
