Hi, I can develop the PLC and HMI program for your building booster pump and lighting control systems based on the provided FDS, including Modbus RTU communication, PID pressure control, pump staging, rotation, alarms, schedules, and commissioning support. The best solution is to first confirm the final PLC/HMI models, VFD register maps, pressure transmitter Modbus map, I/O list, and site wiring details. I’ll then structure the ladder logic with clear sections for auto/manual modes, PID control, pump sequencing, anti-short-cycle timers, runtime rotation, fault handling, lighting schedules, and HMI monitoring screens. I’m comfortable with PLC ladder logic, IEC 61131-3 style programming, Modbus RTU, RS485 communication, VFD control, PID pressure systems, pump staging, HMI screens, alarm history, lighting schedules, and BMS-ready control logic. Deliverables will include: * PLC source program * HMI source program * Pump auto/manual logic * PID pressure control * Pump staging and rotation * Modbus register mapping * Alarm and fault handling * Lighting schedule control * I/O and tag list * Commissioning test support * Backup files and documentation I’ll focus on stable pump operation, clear HMI control, reliable alarms, and well-commented logic that can be maintained easily during future building operation.

Hi, We are available to take this on and get your Building Management System (BMS) working perfectly. The main issue with BMS projects is usually ensuring the energy management and pump control logic integrates seamlessly for real-time monitoring. Are you planning to use a specific IoT protocol for the pump control hardware, and do you want the energy data visualized as a real-time dashboard or exported as periodic reports? We recently developed a similar management system for a commercial facility that needed integrated energy monitoring and automated hardware controls. We used an efficient automation stack to hook into the sensor data and built a responsive interface that validated inputs before updating the system status. We corrected their communication protocols to ensure the data was synced reliably across both local and remote interfaces. Our fix ensured the system operated without downtime and made the management process way faster for their operations team. We are eager to discuss the project further. Reach out to initiate a conversation! Best regards, Quantum Code Solutions

Hi, Your BMS needs to do two things well: track energy use clearly and give reliable pump control with scheduling, remote access, and performance monitoring. That means the system has to be practical on the plant floor and easy to operate day to day. I’ve worked on automation and control systems where monitoring, alarms, and equipment scheduling had to stay stable and simple for operators. I’m comfortable working with energy management logic, control integrations, and HVAC-related systems where reliability matters. My approach would be to define the control points first, then design the monitoring and scheduling flow, and finally build in remote control with clear status feedback and performance logs. I focus on making the system dependable, maintainable, and straightforward to expand later. If you’d like, I can help map the core functions into a clean BMS structure. Best regards, Gabriel
