The short version

  • Each has a real cost: 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.; Johnson Controls Metasys a Metasys server supports 1,300 devices and 65,000 objects, so larger estates require additional servers
  • They diverge on capability: Emerson Ovation covers Power application libraries, Johnson Controls Metasys covers HVAC control.
  • 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.

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.

Johnson Controls Metasys

  • A Metasys server supports 1,300 devices and 65,000 objects, so larger estates require additional servers
  • No hardware requirement, licensing model, subscription term or price is published on the product page; the routes offered are a demo booking and a contact form

Emerson Ovation runs on Windows, On-premise. Johnson Controls Metasys runs on Web, Mobile.
What is Emerson Ovation best used for?
Emerson Ovation is most often used for 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 control, a municipal water authority standardising treatment plant control across several sites under one nerc-adjacent security regime, an ipp wanting the dcs and the safety instrumented system engineered in the same tool rather than integrated across two vendors, hydro operators needing iec 61850 and dnp3 into a control system that also runs the balance of plant. Of those, 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 control and a municipal water authority standardising treatment plant control across several sites under one nerc-adjacent security regime are not what Johnson Controls Metasys is typically brought in for.
What can Emerson Ovation do that Johnson Controls Metasys cannot?
Emerson Ovation covers Power application libraries, Ovation SIS, Embedded historian, NERC CIP tooling. Johnson Controls Metasys covers HVAC control, Building automation, Energy management, Security integration.

Answered from the vendors’ own pages

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.

Johnson Controls Metasys: How much does Johnson Controls Metasys cost?

Johnson Controls Metasys pricing is not published online. Contact Johnson Controls directly for enterprise building automation system pricing and licensing.

Source
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.

Johnson Controls Metasys: What licensing models does Metasys offer?

Specific Metasys licensing models and pricing are available through Johnson Controls sales team. Contact Johnson Controls for custom quotes based on building management requirements.

Source
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.

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.
