Automation Systems Programming (PLC and SCADA)

We specialize in Automation Systems Programming (PLC and SCADA) for water and wastewater treatment plants, offering a full range of services to ensure your systems run efficiently and effectively.

Our expert team develops customized PLC and RTU hardware configurations tailored to your specific needs. We handle complete SCADA/DCS programming, providing seamless control and monitoring of your operations.

We configure reliable communications and radio networks for PLC, RTU, SCADA, and other equipment, ensuring robust and secure data transmission. Our programming services extend to motor starters, including protection relays, soft starters, and variable speed drives, guaranteeing optimal performance and protection.

In collaboration with process and mechanical engineers, we configure instrumentation to achieve precise and accurate measurements. We also reverse engineer existing PLC, RTU, and SCADA programs to integrate new equipment and processes smoothly into your existing systems.

Our team develops and executes comprehensive Factory Acceptance Testing (FAT) and Site Acceptance Testing (SAT) plans to ensure all components meet rigorous quality and performance standards. We coordinate on-site SAT activities with the commissioning team to verify that systems are fully operational before deployment.

We follow all end-user control system change management procedures to ensure compliance and consistency. Additionally, we compile detailed operations and maintenance manuals for PLC, RTU, and SCADA systems, providing valuable resources for ongoing system management.

To ensure your team is fully equipped to operate the new systems, we offer on-site training for end users on control system operations.
