Control Narratives
Process Control Narratives for Manufacturers
For process design specifications, control narratives can be an important component. A clear control narrative is critical during Factory Acceptance Testing (FAT), first-fire testing, and in troubleshooting upset conditions throughout your facility’s lifecycle. Typically, control narratives contain definitions for all of the control loops with additional important information like range, description, alarms, graphic depiction, interlocks, automated logic, and more. In addition to control narratives, other recommended documents include
- Up to date P&ID’s
- Process Flow Diagrams (PFD)
- Operating Manuals or Standard Operating Procedures (SOP)
If you need documentation like this, Cross Company’s Process Solutions group can help. Our well-documented systems are able to work just as well for smaller projects or large, multimillion dollar applications. We accomplish this by specifically tailoring deliverables to match the size and scope of your application, saving you money and providing exactly what you need to succeed.

Why Leverage Cross Company’s Expertise for Your Control Narratives?
An accurate and reliable control narrative is critical for ensuring your systems operate as intended. They should provide a clear roadmap for system behavior and performance. However, a control narrative is only as good as the expertise of the integrator writing it. While these documents are necessary in configuring control systems, translating complex physical processes like complex interlocks or automated logic into clear programming guidance requires extensive industrial expertise.
That expertise is exactly why manufacturers choose to partner with Cross Company. With over 20 years of experience navigating complex process applications, we understand how to design precise control narratives that perfectly align with your operational goals. By partnering with an experienced integrator like Cross, you ensure that your control logic is robust, your operators are thoroughly prepared, and your bottom line is protected.

The Importance of Thorough 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 Cross Can Provide In Your Control Narrative
A well-structured and designed process narrative typically includes the following components. The deliverables can be tailored based on the scope of the application or scale of the project, which is why it’s so important to partner with an experienced integrator who understands your application. Steps include:
- 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.
- Equipment List – This is a comprehensive list of all physical equipment used in the process, including motors, valves, transmitters, and more.
- Software Components – Descriptions of non-physical devices involved in the process, such as control loops, totalizers, calculations, and parameters.
- Alarms – Detailed documentation of non-default alarms associated with the process. These alarms are critical for alerting operators to abnormal conditions.
- 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.
- Concurrent Tasks – Definitions of all normal process control functions that operate independently of sequences
