A free alternative to WinCC and Citect
If you know WinCC or Citect, Scadora will feel familiar: tag tables, animations, system functions and genies work the way you expect, and the software is free to use.
What feels familiar
- In Scadora
- Familiar from
- System functions such as ActivateScreen, SetBit, IncreaseValue
- WinCC
- Appearance, visibility, enable and movement animations
- WinCC
- JavaScript with Tags() and HMI.SysFct()
- WinCC Unified
- Genies with %Tag% substitution and control pop-ups
- Citect / Plant SCADA
- Tag import from a TIA Portal project
- TIA Portal workflow
What is simpler
- One installer with the .NET runtime included
- Own users and roles with no Windows domain
- The server starts with no certificates to configure
- A project is a folder of text files that works with git
- Project edits apply to the running server
What Scadora does not do yet
Scadora is not a drop-in replacement. Check these points against your project.
- It does not open WinCC or Citect projects; only tags can be imported, from TIA Portal
- No redundant server pair
- No encrypted traffic between server and clients
- Windows only
- A young product without industry certifications
