The short version

  • Each has a real cost: EcoStruxure Geo SCADA Expert the ClearSCADA name is retired, so the large body of documentation, forum answers and integrator experience under that name is increasingly stale and does not always match current behaviour.; Siemens WinCC Unified licensing counts PowerTags, and archived tags are licensed separately from displayed tags, so a project that adds historian logging late can breach a tier and trigger an unbudgeted step-up purchase.
  • They diverge on capability: EcoStruxure Geo SCADA Expert covers Point-banded server licence, Siemens WinCC Unified covers TIA Portal engineering.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

EcoStruxure Geo SCADA Expert

  • The ClearSCADA name is retired, so the large body of documentation, forum answers and integrator experience under that name is increasingly stale and does not always match current behaviour.
  • Licensing is point-banded and client-counted with nothing published, and discount depends on your existing entitlement, so a first-time buyer negotiates from a weaker position than an incumbent renewing.
  • The free development mode is capped at 1,000 points and two hours of runtime, which is enough to prototype a screen but not enough to load-test a realistic network before you commit.
  • It is a Windows Server product; there is no Linux server option, so the operating system licensing, patching cadence and hardening burden come with the platform whether you want them or not.
  • Schneider has repeatedly rebranded and repositioned this line, from Control Microsystems to ClearSCADA to EcoStruxure Geo SCADA Expert, which makes long-horizon roadmap commitments hard to trust for a system a utility expects to run for fifteen years.

Siemens WinCC Unified

  • Licensing counts PowerTags, and archived tags are licensed separately from displayed tags, so a project that adds historian logging late can breach a tier and trigger an unbudgeted step-up purchase.
  • There is no migration tool that converts a WinCC V7 project to Unified, so leaving the classic line before its 2027 support end means rebuilding screens, scripts and alarm configuration by hand.
  • Scripting moved from VBScript to JavaScript, which invalidates the script libraries in-house engineers accumulated over a decade on classic WinCC.
  • It is effectively bound to the Siemens controller stack; connecting Rockwell or Mitsubishi PLCs works through OPC UA but loses the shared tag database that is the main reason to buy it.
  • Three unrelated products share the WinCC name, and buyers who specify WinCC without saying Unified, V7 or OA regularly receive quotes for the wrong platform with different licensing and a different contractor pool.

Answered from the vendors’ own pages

EcoStruxure Geo SCADA Expert: Can I still buy ClearSCADA?

No. The product is sold as EcoStruxure Geo SCADA Expert. ClearSCADA is a retired name and current quotes will use the new one.

Siemens WinCC Unified: Should I buy WinCC Unified or WinCC V7?

Unified, for any new project. V7 and V8 receive no new features and support ends in 2027.

EcoStruxure Geo SCADA Expert: How is the server licensed?

By point count, in bands starting around 250 points and scaling to over a million on a single server. Clients are licensed on top, individually or in bundles.

Siemens WinCC Unified: Is WinCC OA the same product?

No. WinCC OA came from ETM, has its own engineering environment and licensing, and is aimed at very large distributed systems. It shares only the brand.

EcoStruxure Geo SCADA Expert: Is there a way to test it for free?

Yes, unlicensed development mode runs up to 1,000 points for two hours at a time. That is a prototyping tool, not a pilot.

Siemens WinCC Unified: What is a PowerTag?

An externally connected process variable in the runtime. Internal tags do not count, but archived tags are licensed separately from displayed ones.

EcoStruxure Geo SCADA Expert: Is Geo SCADA the same as AVEVA Plant SCADA?

No. Plant SCADA is the former Citect product for plant-floor supervisory control. Geo SCADA is the former ClearSCADA product for distributed telemetry. Different codebases, different problems.

Siemens WinCC Unified: Can operators use it from a browser without installing anything?

Yes, the runtime is HTML5, but concurrent browser clients need WebUX or Unified client licences.
