CI-ControlWave EFM Product Features & Overview / 1A-3
Briefly, this library includes function blocks for:
• Average, Compare, Totalize
• Scheduling & Sequencing
• PID & Lead/Lag
• AGA gas flow and liquids calculations
• File handling
In addition, ControlWave ensures data integrity, in the event of a communication
interruption, by storing critical time-stamped alarm and historical data in the controller
memory. This data is then securely retrieved when communication is restored.
