PLC Programming Services for Manufacturing Automation

Optimize Your Production with Custom PLC Programming

Excel Engineering provides expert PLC programming services to support manufacturing automation across a wide range of industries—including food and beverage, automotive, pharmaceutical, and more.

Whether you’re commissioning new equipment or upgrading an existing system, our experienced PLC programmers deliver reliable, custom-tailored control logic that aligns with your specific production goals.

We work with all major industrial platforms, including Rockwell Automation (Allen-Bradley), Siemens, and Modicon, to create seamless, scalable automation solutions that improve efficiency and simplify operations.

What Is PLC Programming?

PLC programming is the backbone of modern industrial automation. Programmable Logic Controllers (PLCs) are digital computers used to control electromechanical systems in manufacturing environments. PLC programming involves writing the code—often in ladder logic, function block diagrams, or structured text—that tells machines when and how to operate.

From assembly lines to process plants, PLCs enable precise, real-time control of everything from motors and valves to conveyors and sensors. Effective programming ensures machines work together safely, efficiently, and in sync with your production needs.
