Industrial Automation

Control System Integration

Connect PLCs, DCS platforms, SCADA, networks, remote I/O, field devices, and plant equipment through controls engineering focused on reliable operations, clear interfaces, and long-term maintainability.

Why Direct

Integration Built Around Your Process

A control system is only as reliable as the way its parts work together. As a control systems integrator, Direct coordinates architecture, programming, I/O, communications, equipment interfaces, testing, and startup around the process so problems are addressed at the system level instead of one device at a time.

Control Systems Integration Engineering

Our Capabilities

Control Systems Integration Services

Control systems engineering, PLC and DCS integration, communications, field integration, validation, and commissioning come together at Direct Automation so the control environment is coordinated through startup.

System Architecture and Interface Design

Direct plans how PLCs, DCS platforms, SCADA, remote I/O, field devices, and other equipment will work together. Our engineers define control-system boundaries, I/O architecture, network requirements, communications, and interfaces before programming begins, giving the integration a clear foundation.

PLC Engineering and System Integration

Our PLC programming translates functional requirements and control narratives into sequences, interlocks, permissives, alarms, and structured logic. We also coordinate drives, remote I/O, and equipment interfaces so the control system operates as intended across connected plant equipment.

DCS Engineering and Communications

Direct engineers DCS applications around process requirements, operator needs, and control strategies. We connect field devices and systems using EtherNet/IP, PROFINET, Modbus, and OPC UA, focusing on reliable communications and integration that's easier to maintain over time.

System Validation and Commissioning

We test programming, communications, sequences, alarms, interlocks, and equipment interfaces before and during startup. This may include factory acceptance testing (FAT), site acceptance testing (SAT), commissioning, and final system backups and updated documentation for the plant team.

Controls Engineering

Systems Engineered to Work Together

Integration isn’t complete when devices can communicate. The goal is a control environment that behaves consistently, is easier to troubleshoot, and gives plant teams a more reliable foundation for future equipment, production changes, and system expansion.

Reduce Integration Surprises

Clear signals, interfaces, communications, logic, and equipment responsibilities help reduce conflicts during field testing and startup.

Simplify System Troubleshooting

Coordinated alarms, data, networks, field devices, and controls help plant teams trace problems across system boundaries more easily.

Plan for Future Changes

Flexible architecture, network capacity, I/O, and interfaces support new equipment, production changes, and additional system connections later.
