At PLC, we provide turnkey engineering services that keep facilities running safely, efficiently, and reliably. Our team specializes in Automation & Control Systems, supporting every stage of a project, in all PLC/DCS/HMI/SCADA platforms —from planning and design to configuration, commissioning, and long-term operations.
Our Control Systems Engineering services cover the full scope of facility automation. We handle everything from reviewing drawings and developing control philosophies to designing system architectures, panel layouts, and cause-and-effect diagrams. We also support vendor integration, factory acceptance testing, and deliver complete as-built documentation, ensuring your systems are designed and built for performance and compliance.
Unlock the power of precision and performance with Control System Engineering — the key to transforming complex processes into seamless, self-regulating systems. Whether you’re optimizing your systems or building from the ground up, PLCs control systems deliver unmatched efficiency, reliability, and intelligence. Our expertise turns data into decisions, motion into mastery, and systems into success. With PLCs Control System Engineering, you’re not just controlling processes — you’re engineering the future.
Ideal for smaller or remote applications, our RTU programming delivers reliable, cost-effective automation for standalone equipment and field sites. As a vendor-agnostic team, we program all major RTU platforms for seamless integration, real-time data, and dependable performance — perfectly scaled for smaller jobs.
For medium-scale automation, our PLC programming provides flexible, high-performance control for production lines, utilities, and facility systems. We’re vendor-agnostic, working across Allen-Bradley, Siemens, Schneider, GE, and more to deliver scalable, efficient solutions that keep your operation running smoothly.
Built for large, complex operations, our DCS programming ensures centralized, reliable control across entire facilities. We’re fluent in Emerson, Honeywell, ABB, Siemens, and other major platforms — delivering robust, scalable automation for enterprise-level performance and process stability.
Enhance your operations with our HMI development services — delivering intuitive, high-performance interfaces that turn complex data into clear, actionable insights. We’re vendor-agnostic, working across all major platforms like Ignition, Wonderware, FactoryTalk, and WinCC to ensure seamless integration with your PLC, DCS, or SCADA systems. From sleek visuals to responsive controls, our HMIs empower your operators to make smarter, faster decisions and keep your facility running at peak efficiency.
Featured Case Study
PLC Construction, Inc. was a contractor for I&E construction, programming, and commissioning services for a 200MMSCFD Cryogenic gas plant in South Texas. PLC’s original scope was the control system hardware specification, PLC programming, HMI development and commissioning. The plant used a redundant Allen Bradley CLX (PCS) and an Allen Bradley GuardLogix (SIS) with a Wonderware HMI. In addition, a smart MCC and switchgear monitoring was integrated into the control system.
Late in the construction phase, PLC was asked to perform ISA 84 Segregation on the control system. PLC mobilized a crew of engineers, programmers, instrument technicians and electricians 6 weeks early to ensure the segregation was properly implemented and there was no delay in schedule.
To achieve this goal, all wiring drawings were updated, our electrical construction crew performed the new I/O terminations and simultaneously our programmers were performing loop checks on the completed panels. The operations staff was embedded in the loop check process from the control room to the field to guarantee thorough training.
