Verification Method
The previous 0–100 scores mixed editorial inputs with unverified market estimates. They are no longer presented as objective rankings. Use these six checks instead:
Licence scope
Record edition, seat model, term, runtimes, add-ons, support and the date of the vendor quote.
Proof workflow
Create, compile, simulate, diagnose, archive and restore the same bounded project in every candidate.
Exact compatibility
Verify controller catalogue number, firmware, OS, languages, safety, motion and HMI support.
Installed-base fit
Use customer standards, local support and stocked spares instead of a generic market-share estimate.
Evidence trail
Keep links to manuals, release notes, lifecycle notices and dated test results.
Exit and limitations
Document export, migration, runtime, commissioning and hardware-test boundaries.
Treat every platform field on this page as a shortlist clue until the exact version is checked against a current primary source. See the testing methodology and submit discrepancies through the correction policy.
