What HYWOS can do
A chat assistant for plants running Siemens WinCC Unified – in German and English.
Live status
Current values, states and alarms from WinCC – with limits; signals with bad quality are flagged.Diagnosis and what-if
Explains why a unit won’t start and what the control system does in a given situation.Plant facts
Equipment, parameters, operating modes and interlocks – always with the source.Signal meaning
Turns raw values like “state 5” into plain language like “Standby”.Verified answers
Numbers, names and quotes are checked against WinCC and the source before they are shown.Read-only by design
HYWOS never writes to the plant and refuses control commands.
What HYWOS brings to operations
Less searching, fewer callbacks, safer decisions.
Faster answers
A plain-language question instead of searching folders, datasheets and screens.Fewer calls to the expert
Plant knowledge is available to every shift – also at night.Fewer wrong decisions
Verified numbers and named sources make every answer checkable.German and English
HYWOS answers in the language of the question – ideal for mixed teams.
Who it’s for
For the people at the plant
Operators
Live status, alarms and what a signal means – without the manual and without a callback.
Shift leads
Quickly understand why a unit is down and what to do next.
Service technicians
Look up interlocks, limits and the right document passage on site.
Commissioning engineers
Check signals, value texts and control logic quickly – always with the source.
