With the Maintenance Station, PCS 7 offers you the possibility to call up information
about the status of all the PCS 7 components in hierarchically structured diagnostics
screens. For this, the data of a component is analyzed with the existing online functions
of the associated tools. You can access the ES data from the diagnostics screens (can
be controlled via access protection mechanisms).
