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.

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.

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.

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.

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.
