ControlDraw Distillation SBC
This web was generated automatically from a sample ControlDraw model.
Move the mouse over the diagram area - you can click on the objects that have numbers by them to go to the detailed diagram for the object. It is a bit like using ControlDraw (but that is much more powerful!)

State Based Control is a plant automation control design based on the principle that
all process facilities operate in recognized, definable Process States that represent a
variety of normal and abnormal conditions of the process. State Based Control,
implemented with the latest developments in object-based technologies, delivers
direct benefits to its adopters in a variety of Operational Excellence categories. It
results in productivity increases, higher asset utilization of both people and process,
automated responses and recovery for abnormal conditions and provides an
environment for knowledge capture directly into the control design.
Process States are characterized by definable differences in processing condition
where changes in rates, product grades, or abnormal conditions dictate changes to
the automation and control parameters of the process. These include but are not
limited to:
operating conditions of equipment (in/out of service, setpoints, etc.)
enabled and disabled alarms,
varying alarm limit values,
loop tuning for optimum performance,
interlocking conditions
operator access to interact with key pieces of equipment
