For a well-known pumping solutions manufacturer, we developed a flexible water and wastewater pumping solution using state-of-the-art PLC hardware and software. As a key person, I designed, proposed, programmed, and commissioned the system for large-scale deployments across the entire continent.

The project required us to develop a highly adaptable pumping control solution using PLC and HMI technology. The system needed to efficiently control a set of pumps for water boosting while being flexible enough to support other applications, such as wastewater transfer and water distribution, without requiring extensive reconfiguration. To achieve this, it had to be fully configurable from the HMI, allowing operators to adjust settings based on the specific requirements of each project and site condition. Additionally, seamless communication with supervisory control systems was essential, necessitating support for BACnet and Modbus TCP protocols. Compatibility with various brands of VFDs was also a key requirement, which we addressed by implementing Modbus RTU communication. This comprehensive approach ensured the solution could be deployed across diverse environments while maintaining reliability, efficiency, and ease of integration.

In various commercial HVAC projects, I leveraged Beckhoff Automation's TwinCAT-based PLCs to develop the control and sequencing logic for chilled water plants. These plants comprised different mechanical components, including water-cooled and/or air-cooled chillers. My role was to create effective control logic to meet the facility's cooling demands. My key responsibilities included programming and testing the system in the field to ensure proper integration with a supervisory control system.
