The short version

  • Each has a real cost: Flow Software the 11,390 dollar Starter licence caps at 250 measures and events, which a multi-line plant exhausts quickly once each line contributes a dozen calculations, forcing a jump to the 62,230 dollar tier.; Rockwell FactoryTalk factoryTalk is a brand, not a product, so a quote that says FactoryTalk may cover any of six separately licensed things; buyers repeatedly find that the demo they saw needed View plus Historian plus a Hub subscription.
  • They diverge on capability: Flow Software covers Calculation engine, Rockwell FactoryTalk covers FactoryTalk View SE and ME.
  • Prices and features above were last checked on 1 September 2026.

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

  • Adding a plant historian quickly where the site has Rockwell distribution support but no PI administrator on staffnot Flow Software

Where each one falls short

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

Flow Software

  • The 11,390 dollar Starter licence caps at 250 measures and events, which a multi-line plant exhausts quickly once each line contributes a dozen calculations, forcing a jump to the 62,230 dollar tier.
  • The Unlimited licence requires every engine on a single server or VM, so any multi-server or multi-site topology goes straight to Distributed at roughly double the price with no intermediate option.
  • Maintenance renews at about fifteen percent of the installed base annually, so a large perpetual estate carries a five-figure recurring cost that the headline perpetual price hides.
  • It is a Windows product with a Microsoft data stack, so Linux or container-native deployment strategies do not apply and the server has to be managed on the plant Windows estate.
  • It calculates and reports but does not collect from equipment itself, so an existing historian or OPC layer is a prerequisite and Flow adds cost on top of that rather than replacing it.

Rockwell FactoryTalk

  • FactoryTalk is a brand, not a product, so a quote that says FactoryTalk may cover any of six separately licensed things; buyers repeatedly find that the demo they saw needed View plus Historian plus a Hub subscription.
  • Licensing units differ per product, tags for Historian, display tags and clients for View, another scheme for Optix, which makes forecasting the cost of a plant expansion genuinely hard.
  • The migration of products onto FactoryTalk Hub subscriptions converts what used to be a perpetual licence into an annual payment where lapsing stops the software, changing a capital purchase into an operating one you cannot exit.
  • Value drops sharply outside an Allen-Bradley estate; against a Siemens or Mitsubishi PLC you are back to OPC UA and lose the main reason to buy FactoryTalk at all.
  • There is no public price list and buying is through distribution, so two plants of identical size in the same company can pay materially different amounts depending on when and how they negotiated.

Answered from the vendors’ own pages

Flow Software: Does Flow publish real prices?

Yes. Starter is 11,390 USD perpetual for 250 measures, Unlimited is 62,230 USD perpetual or 16,595 USD a year, and Distributed is 128,450 USD perpetual or 34,250 USD a year.

Rockwell FactoryTalk: Is FactoryTalk Historian the same as AVEVA PI?

It is built on the PI engine under an OEM arrangement, tuned for Rockwell integration. If you already run PI enterprise-wide, buying Historian too usually duplicates a system you have.

Flow Software: Is perpetual licensing still offered?

Yes, at every tier, with the first year of maintenance included and renewal at roughly fifteen percent per year. Subscription is available on Unlimited and Distributed only.

Rockwell FactoryTalk: Can I still buy FactoryTalk perpetually?

Some products yes, but the direction is toward FactoryTalk Hub subscriptions. Confirm per product before assuming a capital purchase is available.

Flow Software: Do I need a historian as well?

Effectively yes. Flow reads from historians, databases and OPC sources; it is a calculation layer, not a data collector.

Rockwell FactoryTalk: Does FactoryTalk work with non-Rockwell PLCs?

Yes, through OPC UA and drivers, but the native tag browse advantage disappears and the case for FactoryTalk over a cheaper independent SCADA weakens.

Flow Software: What counts as a measure?

Each configured KPI or event definition. A single line typically consumes ten to thirty, which is what makes the 250 Starter cap tighter than it looks.

Rockwell FactoryTalk: Where do I find pricing?

You cannot without a distributor. Rockwell publishes no list pricing for the FactoryTalk portfolio.
