Where each one falls short

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

EcoStruxure Geo SCADA Expert

  • The ClearSCADA name is retired, so the large body of documentation, forum answers and integrator experience under that name is increasingly stale and does not always match current behaviour.
  • Licensing is point-banded and client-counted with nothing published, and discount depends on your existing entitlement, so a first-time buyer negotiates from a weaker position than an incumbent renewing.
  • The free development mode is capped at 1,000 points and two hours of runtime, which is enough to prototype a screen but not enough to load-test a realistic network before you commit.
  • It is a Windows Server product; there is no Linux server option, so the operating system licensing, patching cadence and hardening burden come with the platform whether you want them or not.
  • Schneider has repeatedly rebranded and repositioned this line, from Control Microsystems to ClearSCADA to EcoStruxure Geo SCADA Expert, which makes long-horizon roadmap commitments hard to trust for a system a utility expects to run for fifteen years.

OSIsoft PI System

  • OSIsoft is now AVEVA and osisoft.com redirects to the AVEVA PI System pages
  • No pricing is published; osisoft.com/pricing resolves to AVEVA product pages with no rate, minimum or cost driver
  • Licensing runs through the AVEVA Flex Subscription Program rather than a published per-seat or per-tag price
  • The PI System is split across separately listed products including PI Server, PI Vision, PI Data Infrastructure and Edge Data Store
