Testing & Commissioning: Performing \\"Point-to-Point\\" checks to ensure every wire is connected correctly and the hardware powers up without faults. PLC Programming Logic Development: Writing code (usually in Ladder Logic or Function Block Diagram) to maintain set points, manage compressor cycles, and handle PID loops for precise temperature control. Safety Interlocks: Programming \\"trip\\" conditions (e.g., high pressure or motor overheat) to shut down the unit and prevent damage. Visualization: High-resolution graphics showing real-time status of fans, compressors, and airflow. Control: Allows operators to change set points or manually override a unit from a central computer Alarm Management: Logging every fault with a timestamp for troubleshooting. Online Monitoring with Offline Reporting Online Monitoring: Continuous, live data streaming from the AC units Offline Reporting with PLC to programme control over the contactors of each load group. Hardware Interface: The (Direct Digital Controller) or a secondary PLC uses Digital Output (DO) modules to trigger interposing relays. These relays, in turn, control the coil circuit of the main contactors for the AC units or motors. |
| 18 | Feedback Loop: A Digital Input (DI) from the DG’s control panel (e.g., a \\"Potential Free Contact\\" for 'DG on Load') tells the BMS to initiate the sequence. The logic is typically based on either a fixed time delay or a \\"Smart Sensing\\" approach. This is the most common approach. Each group of loads is assigned a specific delay after the DG signal is received. Group 1 (Priority): Starts at T + 0 seconds (Emergency lighting, critical fans). Group 2: Starts at T + 15 seconds (First block of ACs). Group 3: Starts at T + 30 seconds (Second block of ACs). Logic: T_{delay} > the time required for the DG's AVR (Automatic Voltage Regulator) to stabilize after the previous group's inrush. With monitors the total current (I) and frequency (f). It only triggers Group 2 once the current has dropped from its peak (Inrush) back to a steady state and the frequency has returned to 50 Hz. The system automatically archives data into a database (like SQL). You can generate PDF or Excel reports daily, weekly, or monthly to analyze energy consumption and performance trends without needing a live connection. Series Cyber Secure Main PL with era of industrial hacking, \\"Level 2\\" (L2) security is critical. Hardware: A specialized PLC designed with built-in encryption and secure boot features. Cyber Security: Includes features like Role-Based Access Control (RBAC), disabled unused ports, and encrypted communication protocols to ensure that unauthorized users cannot \\"hijack\\" the AC system. Web Application (Web Enabled) taking the data beyond the local control room. Accessibility: Using a web server (often hosted on the PC or a cloud gateway), authorized users can view the AC status via a standard browser (Chrome/Edge) on their phones or laptops. Responsive Design: The interface scales to fit mobile screens, providing a \\"glass cockpit\\" view of the facility from anywhere in the world. Testing and Commissioning (T&C) FAT (Factory Acceptance Test): Testing the panel and code at the workshop before shipping. SAT (Site Acceptance Test): Testing the full system on-site with actual AC loads. Loop Checking: Verifying that a 5°C change at the sensor shows up as exactly 5°C on the Web App. |
