This eBook examines the attributes of state based control and the value delivered to manufacturing from the initial design through the operating life of the facility by improving the effectiveness of operators.
Processes operate in a number of different states which range from down-time for maintenance to running in steady state and any normal or abnormal state in between. State based control uses the state or mode that the process is in to optimize the control of the process.
The result of this is a plant that performs better over the entire range of states for safety and asset utilization. The use of standardized established architecture can reduce the time and effort to implement the control system with improved performance.
Operational process knowledge is captured and leveraged in the design process. This keeps the knowledge of the best operator on the board at all times and reduces training demands. This knowledge, once captured, can also be leveraged through the corporation, improving the return on the initial investment. All of the operators on the board can manage the process at a higher level based on the experience and collective knowledge of everyone running the plant. This causes the plant to become smarter over time.
