@AwaisChaudhry

Hello, I understand you need a complete PLC and HMI solution for a small water pumping station with 2 pumps, VFDs, and a 4-20 mA pressure transmitter. The goal is to maintain target pressure using a PID loop, switch between pumps with proper interlocks, and present clear graphics, alarms, and set points on the Siemens Unified Basic HMI. My approach is to design a robust control sequence in Siemens S7-1200 with PID on the pump speed, implement safe interlocks and automatic alternation, and build intuitive HMI screens for pump status, pressures, alarms, and override functions. I will ensure proper wiring, a clean PLC program structure, scalable HMI layouts, and thorough testing with simulated and live signals to validate performance. What are the required alarm tiers and any specific safety interlocks beyond basic pump alternation and pressure control that I should implement? Best regards,

@romanpotapcz

Hello! I can develop the complete PLC and HMI program for your small water pumping station using Siemens S7-1200 1212C PLC and Siemens Unified Basic HMI, implementing PID control on the PLC to maintain the desired water pressure using the 4-20 mA signal from the pressure transmitter, alternating between the two pumps to balance wear, configuring all interlocks to ensure safety and prevent faults, integrating graphics, set points, alarms, and visualization on the HMI for real-time monitoring, ensuring that the VFDs respond correctly to the PID output, programming the HMI screens to clearly display pump status, pressure readings, set point adjustments, and alarm conditions, thoroughly testing all logic to confirm accurate pressure control, proper pump alternation, interlock operation, and VFD coordination, and delivering well-documented, maintainable code so your team can operate, adjust, and expand the system confidently, ultimately providing a robust, safe, and fully operational water pumping station automation solution ready for deployment and commissioning. Hello!

@tanithk

Hey — saw your post about developing the PLC and HMI for a small water pumping station with 2x pumps and VFDs. A common pain point on these setups is getting clean, reliable switchover and lead/lag logic so both pumps share runtime and don’t fight each other. Quick question before I suggest an approach: Do you already have a preferred PLC/HMI platform (Siemens, Allen-Bradley, Schneider, etc.), or is that still open? I’ve built similar pump station controls with VFDs, including hard-wired interlocks, auto/hand modes, and clear HMI status/alarms for operators. If you can share the I/O list, P&ID, or any panel drawings you have, I’ll review them and outline how I’d structure the PLC logic and HMI screens.

@AbPLCMan

Hello I can develop the PLC and HMI program for your water pumping station based on my 11 years of experience in Siemens automation systems (PLC, HMI, drives, and industrial process control). Relevant Experience 11+ years working with Siemens PLC platforms (S7-300/400, S7-1200/1500) and HMI/WinCC environments. Extensive experience with pump control, PID loops, VFD integration, and industrial process automation. Commissioned and optimized control systems in water, beverage, and industrial process applications. Proposed Solution PLC program to control 2 pumps with VFDs (hardwired control). PID pressure control using the 4–20 mA pressure transmitter to maintain the desired setpoint. Pump alternation logic (lead/lag rotation for balanced runtime). Complete interlocks and protection logic (faults, pump feedback, pressure limits, etc.). HMI development including: System overview graphics Pressure monitoring Setpoint adjustment Alarm and fault display Pump status and runtime information The system will be designed for stable pressure control, reliable pump operation, and easy operator interaction through the HMI. I can also assist with testing, tuning the PID loop, and remote commissioning support if required.

@sadam61

Hi, I’ve carefully reviewed your project on developing a PLC and HMI program for the water pumping station, and I’m excited about the opportunity to contribute. With over 9 years of experience in automation and control systems, I have successfully completed similar projects involving Siemens PLCs and HMIs. I can efficiently design the PLC code to control the pump speeds with a PID regulator, ensuring optimal water pressure. My familiarity with VFDs, pressure transmitters, and HMI graphics will allow me to implement all the necessary functionalities like interlocks, alarms, and set points effectively. I am ready to start the project immediately and can guarantee a smooth and professional execution.

@zeldac1

Hi there, I see you’re building a PLC/HMI solution for a small water pumping station with 2 pumps and VFDs, plus a 4-20mA pressure transmitter. A common pitfall is tuning PID for variable-speed pumps without accounting for head curve and VFD dynamics, which can cause oscillations or slow response. Action plan: - Map I/O, setpoints, and interlocks for auto/alternate pump control - Implement PID on pressure with safe anti-windup and alarm logic - Build clear HMI: trends, alarms, setpoints, and robust start/stop sequences I’ve done a similar water-well/transfer project with Siemens S7-1200 and Unified Basic HMI; achieved stable pressure within ±0.2 bar and reliable fault handling.

@Lazarone1

Hi, that’s great to hear! Your project closely aligns with one I recently completed. In that project, I built a fully automated water distribution control system using Siemens S7-1200 PLCs, Unified HMI panels, and VFD‑driven pump control with integrated PID loops, interlocks, and alarm handling. Your setup with dual VFD pumps, a 4-20mA pressure transmitter, alternating sequences, and full HMI visualization fits perfectly with my expertise. I can implement stable PID pressure control, pump protection logic, and clean, intuitive Unified HMI screens with alarms, trends, and setpoints. I’d be glad to connect and share my experience in more detail over chat. Thank you. Best regards, Lazar

⭐⭐⭐⭐⭐ ✅Hi there, hope you are doing well! I have successfully developed PLC and HMI programs for similar small water pumping stations where pump speed was controlled via VFDs using PID loops to maintain pressure efficiently and alternate pumps seamlessly. The most important part of this project is precise PID tuning and interlock configuration to ensure smooth pump operation and reliable pressure control. Approach: ⭕ I will configure the Siemens 1212C PLC to implement PID control for pressure regulation ⭕ Program alternating pump operation and interlocks for safe and efficient control ⭕ Develop HMI graphics, alarms, and setpoint interfaces on Siemens Unified Basic ⭕ Test the integrated system with pressure transmitter feedback for performance ❓ Could you please share the complete functional description and any specific alarm or graphic requirements? I am confident in delivering a robust, user-friendly PLC and HMI solution tailored exactly to your water pumping station needs. Thanks, Nam
