Control Narratives

Cross Company 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!

Understanding Control Narratives

Control narratives are indispensable for ensuring that a control system operates as intended, providing operators and engineers with a clear roadmap for system behavior and performance.

Control narratives are a subset of design specifications, and they serve as a critical tool in configuring control systems. While larger projects may require extensive documentation, smaller systems can often be effectively managed with just a control narrative. These narratives contain a wealth of information, including:

Control loop definitions

Graphic depictions


Automated logic

Purposes of Control Narratives

There are several essential purposes served by control narratives. Some of those include

Operational procedures – control narratives allow process engineers to set out and record operational procedures on the plant floor, ensuring that operators understand how the system should be operated

Operator training – control narratives also provide documentation for operator training, enabling operators to fully understand the equipment, variables, and processes they’ll be managing

Programming guidance – control narratives are also a starting point for control system programmers, even for those who may have limited experience with a specific process. The control narrative provides insights into how the control system should be configured.

This knowledge serves as a foundation for developing control logics for Distributed Control Systems (DCS) or Programmable Logic Controllers (PLC), allowing for effective system automation.

Components of a Control Narrative

Well-structured control narratives include the following components:

  1. Process Overview. This includes a basic description of the overall system processes, purposes, and functions. Also included are descriptions of major functional units, subsystems, and their interactions as well as an overview of the process timeline by functional unit.
  2. Equipment List. This is a comprehensive list of all physical equipment used in the process, including motors, valves, transmitters, and more.
  3. Software Components. Descriptions of non-physical devices involved in the process, such as control loops, totalizers, calculations, and parameters.
  4. Alarms. Detailed documentation of non-default alarms associated with the process. These alarms are critical for alerting operators to abnormal conditions.
  5. Process Functionality Description (Interlock and Sequence). This is step-by-step descriptions of how the processes or units work. This includes sequences, set points and steps. It also includes documentation of interlocks.
  6. Concurrent Tasks. Definitions of all normal process control functions that operate independently of sequences.

Did you know… Cross Company is an ESOP (Employee Stock Ownership Plan). Our ESOP started in 1979 and as of 2006, we are 100% employee-owned! Learn more about our ESOP and how that benefits both team members and our customers.
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 of paper is about 4.5 grams, that’s 4.5 million micrograms.
Did you know… Cross Company has grown significantly since our start in 1954. Over the years we've acquired 26 companies! Today, our five groups have expertise in everything from industrial automation to precision measurement, and industry knowledge going all the way back to 1939.
