What to do if Siemens SIMATIC ET 200S IM151-1 FO STANDARD Control Unit ET 200S does not start due to configuration error?

If your Siemens Control Unit (ET 200S) fails to start and indicates a configuration error, it might be due to multiple power module entries ending in ...O or ...SO. To resolve this, review and correct the configuration within HW Config. Alternatively, the error could arise from the absence of power module entries ending in ...O or ...SO. In this case, add a power module entry ending in ...O or ...SO using HW Config.
