Technical details and manufacturing context for Sequence Controller

Definition
The Sequence Controller is a critical component of the Recovery Sequencer that orchestrates the precise sequence of recovery operations. It ensures that each step in the recovery process is initiated at the correct time and in the proper order, coordinating with other system components to achieve controlled restoration of equipment or processes after shutdowns, faults, or maintenance events.
Working Principle
The Sequence Controller receives input signals from sensors and system commands, processes them through programmed logic or algorithms, and outputs control signals to actuators, valves, motors, or other devices according to a predefined sequence. It typically uses timers, counters, and state machines to manage transitions between different stages of the recovery process.
