SCADA architecture: a design guide from field to control room
Design SCADA systems that scale — field layer, communications, servers, redundancy, and alarming — without painting the project into a corner.
SCADA
Live supervision, alarming, and operator control.
Supervisory control and data acquisition: live visualization, alarming, operator control, and short-term trending over controllers and field devices. Time horizon is now — seconds to shifts — with history handed to historians and production context to MES.
