The short version

  • Each has a real cost: COPA-DATA zenon the I/O count that determines your licence band is a weighted calculation, not a variable tally, so projects sized from a tag list routinely land in a higher and more expensive band than budgeted.; 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.
  • They diverge on capability: COPA-DATA zenon covers I/O-banded licensing, Flow Software covers Calculation engine.
  • 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.

COPA-DATA zenon

  • The I/O count that determines your licence band is a weighted calculation, not a variable tally, so projects sized from a tag list routinely land in a higher and more expensive band than budgeted.
  • The integrator and engineering talent pool is concentrated in German-speaking Europe; a North American or Asian site can find itself dependent on a single partner with no competitive quote available.
  • English-language documentation and community material lag the German equivalents, which slows engineers who are learning the product without formal COPA-DATA training.
  • The annual software maintenance contract is a percentage of licence value, so a large I/O estate carries a recurring cost that does not fall even when the plant is stable and nothing is changing.
  • Third-party ecosystem extensions are far fewer than for Ignition or FactoryTalk, so requirements outside the box tend to become custom engineering billed at partner day rates.

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.

Answered from the vendors’ own pages

COPA-DATA zenon: How is a zenon licence sized?

By calculated I/O count. Numeric variables are weighted upward in that calculation and binary values counted singly, so ask your partner for the calculated figure, not the variable count, before signing.

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.

COPA-DATA zenon: Is zenon only for factories?

No. A significant part of its installed base is electrical substation automation, where IEC 61850 support is native rather than an add-on.

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.

COPA-DATA zenon: Is there a free version?

There is a demo mode for evaluation and a free educational licence, but production runtime always needs a paid, I/O-banded licence.

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.

COPA-DATA zenon: Can zenon replace a PLC?

zenon Logic is an IEC 61131-3 soft PLC and can control non-safety-critical processes, but most deployments keep a hardware PLC and use zenon for visualisation and supervision.

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.
