We design and implement the control logic that governs how systems operate — including equipment sequencing, interlocks, process control loops, and alarm handling.   Our process includes:

• P&ID Drawing Creation

• Process control strategies and system architecture 

• Equipment sequencing and operational logic 

• Interlock development for safe system operation 

• Fail-safe and abnormal condition handling 

• Control narratives and functional descriptions 

• Detailed electrical drawing package per NFPA-79 standards

PLC programming follows a structured methodology focused on well-defined interfaces between program elements, resulting in scalable and reusable code. FDS Engineering primarily utilizes Rockwell Automation platforms with Ladder Logic and Function Block programming, while also applying Structured Text where appropriate. Experience includes multiple PLC platforms and programming in accordance with IEC 61131-3 standards, with an emphasis on clarity, consistency, and ease of troubleshooting. 

The Interface—whether referred to as "HMI" or "Operator Interface Terminal" — is the operator’s primary view into the process, and is designed accordingly. FDS Engineering develops interfaces based on High Performance HMI principles, emphasizing clarity, situational awareness, and effective decision-making. Graphics are intentionally simplified, with restrained use of color and consistent status indication to highlight abnormal conditions rather than distract from them. Alarm systems are developed in accordance with ISA standards, ensuring meaningful prioritization and actionable information. Integrated trends and reporting tools provide operators and management with immediate insight into system performance, enabling informed operation rather than reliance on cluttered, color-saturated displays. 

Control panel designs are developed in accordance with UL 508A requirements and established industry standards, ensuring safe, compliant, and maintainable systems. FDS Engineering provides complete design packages including detailed bills of material, panel layout drawings, and wiring diagrams. Documentation is structured for clarity and usability in both fabrication and field installation, with clear terminal designations, device labeling, and field connection details. The result is a control panel design that supports efficient manufacturing, straightforward installation, and long-term serviceability.
