Evocon is the right choice for manufacturers whose primary need is visual, high-adoption OEE monitoring with PLC connectivity and excellent support. Not recommended where API integrations or predictive maintenance are requirements.
AVEVA is the right infrastructure choice for large process manufacturers and utilities operating at enterprise scale. The PI System ecosystem is deeply entrenched in oil and gas, power, and chemical processing — often the foundational layer on which other tools are built.
