The short version

  • Each has a real cost: AVEVA System Platform wonderware is no longer a name you can buy; if you have inherited documentation, purchase orders or job specifications that say Wonderware, everything has to be re-mapped to AVEVA product names before you can quote it.; Emerson Ovation nothing about the cost is published, and the licence is a minority of the total; engineering, I/O hardware and commissioning commonly exceed it, so a budget built from a software quote will be wrong by a large multiple.
  • They diverge on capability: AVEVA System Platform covers ArchestrA object model, Emerson Ovation covers Power application libraries.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

AVEVA System Platform

  • A water utility with a decade of ArchestrA templates where rewriting to another platform cannot be justifiednot Emerson Ovation
  • A pharmaceutical line needing ISA-88 batch recipe handling above existing Rockwell and Siemens controllersnot Emerson Ovation
  • A plant modernising legacy InTouch applications without discarding the existing screens and scriptsnot Emerson Ovation

Emerson Ovation

  • Replacing an end-of-life control system on a coal or gas unit during a planned outage, where the vendor must supply turbine control as well as plant controlnot AVEVA System Platform
  • A municipal water authority standardising treatment plant control across several sites under one NERC-adjacent security regimenot AVEVA System Platform
  • An IPP wanting the DCS and the safety instrumented system engineered in the same tool rather than integrated across two vendorsnot AVEVA System Platform
  • Hydro operators needing IEC 61850 and DNP3 into a control system that also runs the balance of plantnot AVEVA System Platform

Where each one falls short

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

AVEVA System Platform

  • Wonderware is no longer a name you can buy; if you have inherited documentation, purchase orders or job specifications that say Wonderware, everything has to be re-mapped to AVEVA product names before you can quote it.
  • AVEVA Flex converts licensing to a recurring subscription draw-down, so organisations that budgeted for a perpetual licence with a support percentage face a materially different cost model at renewal.
  • It is Windows only, and version compatibility between System Platform, Historian and InTouch is tight, so upgrades are coordinated projects rather than incremental patches.
  • The ArchestrA object model has a steep learning curve and small systems end up paying for structure they do not need, which is why integrators often deploy standalone InTouch instead.
  • Licence enforcement counts I/O aggressively and unexpected tag growth during commissioning can trigger a mid-project licence purchase at list price.

Emerson Ovation

  • Nothing about the cost is published, and the licence is a minority of the total; engineering, I/O hardware and commissioning commonly exceed it, so a budget built from a software quote will be wrong by a large multiple.
  • Ovation is power and water specific, so a group operating both power stations and chemical plants will end up running Ovation alongside DeltaV or a third-party DCS and paying for two engineering skill sets.
  • The annual support and subscription contract is effectively mandatory: without it you lose access to security patches, which for a NERC CIP regulated asset is not a decision you can defer.
  • Replacement is bounded by outage windows rather than by budget, so a decision to leave Ovation typically takes multiple years and cannot be reversed cheaply once started.
  • Third-party engineering capability is much thinner than for Rockwell or Siemens platforms, so you are largely dependent on Emerson or a small partner pool for changes, and their day rates set the cost of every future modification.

Answered from the vendors’ own pages

AVEVA System Platform: Is Wonderware still sold?

No. The brand was retired; buy AVEVA System Platform, AVEVA InTouch HMI, AVEVA Historian or AVEVA Plant SCADA instead.

Emerson Ovation: Is Ovation the same as DeltaV?

No. Ovation targets power generation and water; DeltaV targets chemicals, life sciences and refining. They are separate products with separate engineering tools and separate support organisations.

AVEVA System Platform: Can I still buy a perpetual licence?

AVEVA steers new business to Flex subscriptions. Perpetual is increasingly restricted to existing agreements and renewals.

Emerson Ovation: Can I get a price without talking to Emerson?

No. There is no published price list, no trial and no self-service configurator. Every Ovation number comes through Emerson or a certified partner.

AVEVA System Platform: Do my old InTouch applications still run?

Yes, legacy InTouch applications are supported in System Platform, though the older graphics do not gain the newer situational-awareness features without rework.

Emerson Ovation: Does Ovation 4.0 mean I can stop buying Emerson hardware?

No. The software-defined architecture virtualises controllers, but the I/O and field interfaces are still Emerson hardware and are still the bulk of the equipment cost.

AVEVA System Platform: What is AVEVA Flex?

A subscription credit pool you draw against for any AVEVA product, which trades a fixed licence for a recurring balance you must keep topped up.

Emerson Ovation: What decides the price?

Controller count, I/O point count and the number of operator workstations, plus the engineering hours to configure the control logic for your plant.
