The short version

  • Each has a real cost: 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.; Yokogawa CENTUM VP there is no published price list and no way to size a budget without engaging Yokogawa or an EPC, so early-stage comparison against DeltaV or Experion is guesswork until quotations arrive.
  • They diverge on capability: Siemens WinCC Unified covers TIA Portal engineering, Yokogawa CENTUM VP covers Field Control Station.
  • 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.

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.

Yokogawa CENTUM VP

  • There is no published price list and no way to size a budget without engaging Yokogawa or an EPC, so early-stage comparison against DeltaV or Experion is guesswork until quotations arrive.
  • Engineering and commissioning routinely cost several times the hardware and software, and owners who budget from the equipment quote alone are consistently short.
  • The ecosystem is closed: controllers, I/O and diagnostics are Yokogawa, and third-party alternatives at the controller layer do not exist, so the vendor holds pricing power for the twenty years or more the plant runs.
  • Operator stations run on Windows and are tied to specific validated Windows releases, so operating system end-of-life forces console refresh cycles that are governed by Yokogawa validation rather than by your IT policy.
  • Engineering staff who know CENTUM are scarce outside Japan, the Middle East and South East Asia, and in North America and Europe you will pay a premium or depend on Yokogawa’s own services organisation for changes.

Answered from the vendors’ own pages

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.

Yokogawa CENTUM VP: Can I upgrade from CENTUM CS 3000 without rewiring the plant?

Yes. Yokogawa sells migration packages that replace the controller and keep existing field wiring and marshalling, which is the main reason CENTUM installations stay CENTUM.

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.

Yokogawa CENTUM VP: Is CENTUM VP sold as a subscription?

No. It is a capital purchase of hardware and licences with an annual service agreement for updates and support.

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.

Yokogawa CENTUM VP: How does it compare with Emerson DeltaV on cost?

Neither publishes prices. CENTUM tends to win on brownfield migration cost because the field wiring stays; DeltaV tends to be cheaper on small greenfield systems.

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.

Yokogawa CENTUM VP: Do I need a separate safety system?

Yes, for SIL-rated functions. ProSafe-RS is the Yokogawa SIS and shares the CENTUM engineering database and operator console.
