Animation and process trends linked to script logic

State Management

Tags maintain current process values

Scripts update HMI objects and alarms

Runtime maintains execution state for event triggers

Database scripts maintain persistent logs

Global script variables accessible across procedures

Data Management

Tags represent real-time process data

Scripts read/write data to HMI, PLC, or database

Historian stores process events and measurements

Data accessed via runtime, HMI screens, or reports
