Description:
This entry provides you with information on possible diagnostics messages you might get when commissioning an ET 200S as PROFINET IO device.

Proceed as follows to determine the diagnostics message.

  • In the SIMATIC Manager, you open the menu "PLC > Show Accessible Nodes" to diagnose the separate nodes of the PROFINET IO system.
  • Right-click the PROFINET IO device you wish to diagnose and select the menu "PLC -> Module status".
  • The "Module Status" dialog opens.
  • In the "IO Device Diagnostics" tab you see the standard diagnostics message of the PROFINET IO device which you might get during commissioning.

The following standard diagnostics message indicates that there is not termination module slotted in the ET 200S. You also get this standard diagnostics message when more than one module of the ET 200S station has been removed.

The standard diagnostics message "Module missing..." indicates that a module in the ET 200S has been removed. Check whether a module is slotted in the specified slot in the ET 200S station.

The standard diagnostics message "Incorrect module..." indicates that a different module to the one slotted in the ET 200S has been configured. Check in the STEP 7 hardware configuration whether the module you have configured for the slot specified is the one that is slotted in that slot in the ET 200S station.
