Control narratives can be subset of a design specification. For smaller systems sometimes supplying just a control narrative will provide all the information required to configure the control system.
Define Control Loops
Typically Control Narratives contain definitions of all control loops with important details like range, description, alarms, graphic depiction, interlocks, automated logic etc. In addition to having a control narrative other documents are recommended:
- Up to date P&ID’s
- Process Flow Diagrams (PFD)
- Operating Manuals or Standard Operating Procedures (SOP)
