A Structured Approach to process of Control System Integration

Control Narrative (Concept Note)

The detailed instrumentation consulting engineering team invests time to understand:

• P&I Diagrams
• Cause-Effect Charts
• Scenario Documents

The team communicates unit operation requirements to logic and graphic programmers, ensuring they have visibility into:

• Functional logic
• Interlocks
• Alarms

Control System Architecture

Design focused on:

• Centralized Control Room Operations
• Remote Field Operator IS PC HMI
• Zone 1 Remote I/O / Control Room I/O
• Server-Client vs. Stand-Alone Architectures
• Redundancy
• Network Protocols
• Data Historian & Reporting
• Scalability
• Intelligent MCCs

Programming & Graphics Development

The programming and graphics team, after understanding unit operations, selects appropriate programming languages, including:

• FBD (Function Block Diagram)
• SFC (Sequential Function Chart)
• Structured Text
• Ladder Logic

They prepare the logic and graphics to demonstrate plant operations during Software Factory Acceptance Testing (SWFAT) using simulation software.

Marshalling Panel Testing

The marshalling panel team conducts Hardware Factory Acceptance Testing (HWFAT) and utilizes these results during commissioning to:

• Save time
• Ensure “Right First Time” automation solution delivery

Validation

The validation team writes test scripts and prepares for system staging to execute Software FAT tests on simulation software, documenting tests according to: GAMP-5 Methodology
