Control Narratives

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. 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)

This is precisely where Cross Company can provide the most benefit. We tailor our deliverables to match the size and scope of the project thus saving you money. Our documented systems work well for very small projects on up to large multimillion dollar projects. We can assist you in the creation of your control narrative and even interrogate an existing control system to determine how it is currently programmed. With over 20 years of experience in working on all types of projects, we can do exactly what needs to be done. Start a conversation with a Cross expert!

Did you know... the precision measurement group at Cross was founded in 1939 by our current CEO's grandfather, Jim King. That's a whole lot of calibration!
Did you know... A fingerprint weighs about 50 micrograms. We know, we weighed it! The residue left from a finger can actually make a difference in weight results which is why we wear gloves when we calibrate weights. For reference, a sheet to paper is about 4.5 grams, that’s 4.5 million micrograms.
Did you know… Cross Company is an ESOP (Employee Stock Ownership Plan). Our ESOP started in 1979 and as of 2006, we are a 100% employee owned! Learn more about our ESOP and how that benefits both team members and our customers.
