SCADA Integration
Connect Your Industrial Systems for Greater Visibility and Control
Industrial facilities often contain equipment, PLCs and control systems from different manufacturers, installed at different times and using different communication technologies. Without effective integration, valuable operational data can remain isolated across individual machines and production areas.
SCADA integration brings these systems together, providing operators and engineering teams with centralised visibility of production, equipment status, alarms and process performance.
At Stratos, we provide SCADA integration services that connect PLCs, HMIs, industrial networks and automation equipment into a unified monitoring and control environment, helping manufacturers improve visibility, simplify operations and make better use of their production data.
What Is SCADA Integration?
SCADA integration is the process of connecting a Supervisory Control and Data Acquisition system with PLCs, machines, instrumentation and other industrial automation equipment.
A successful integration allows information to move reliably between systems so operators can monitor and, where appropriate, control processes from a central SCADA platform.
Integration may include:
• PLC connectivity.
• Machine integration.
• HMI integration.
• Industrial communication networks.
• Remote I/O.
• Variable Speed Drives.
• Motor Control Centres.
• Instrumentation.
• Existing automation systems.
• Third-party equipment.
The objective is to create a connected automation environment without unnecessarily replacing equipment that remains suitable for operation.
PLC and SCADA Integration
PLCs provide much of the real-time information required by a SCADA system.
Effective PLC integration allows SCADA to access information such as:
• Equipment status.
• Process values.
• Motor conditions.
• Production states.
• Alarms and faults.
• Setpoints.
• Instrument readings.
• Operating modes.
Our engineers work with multiple PLC platforms, including Siemens, Allen-Bradley, Mitsubishi Electric, Omron and Schneider Electric, allowing SCADA systems to be integrated across both single-vendor and mixed automation environments.
Integrating Existing Automation Systems
Many industrial sites have developed over decades rather than being built around a single automation architecture.
A facility may contain several generations of PLCs, standalone machines and different communication protocols.
SCADA integration can provide a common supervisory layer across these systems, reducing the need for operators to monitor individual machines separately.
Our engineers assess the existing infrastructure to determine how equipment can be connected while minimising unnecessary hardware replacement and production disruption.
Industrial Communication Networks
Reliable communication is fundamental to successful SCADA integration.
Depending on the existing equipment and system requirements, integration may involve industrial communication technologies such as:
• PROFINET.
• PROFIBUS.
• EtherNet/IP.
• Modbus TCP.
• Modbus RTU.
• OPC UA.
• CC-Link.
• Industrial Ethernet.
The appropriate communication architecture depends on equipment compatibility, performance requirements and the existing automation infrastructure.
Integrating Machines and Production Lines
SCADA can provide centralised visibility across individual machines or complete production lines.
Integration can allow operators to monitor:
• Machine availability.
• Running and stopped conditions.
• Production status.
• Fault conditions.
• Process values.
• Motor performance.
• Production counts.
• Operating modes.
Bringing this information together helps production and maintenance teams understand what is happening across the facility without relying on individual machine interfaces.
Alarm Integration
SCADA integration enables alarms from multiple PLCs and machines to be presented within a centralised system.
This can help operators identify:
• Equipment faults.
• Process deviations.
• Communication failures.
• Motor trips.
• Safety conditions.
• Production interruptions.
Structured alarm management makes it easier to identify where problems are occurring and prioritise the conditions requiring attention.
Data Integration and Historian Systems
Operational data generated by PLCs can provide valuable insight when collected and analysed over time.
SCADA integration can enable information to be recorded for:
• Historical trending.
• Production analysis.
• Fault investigation.
• Downtime analysis.
• Process optimisation.
• Energy monitoring.
• Maintenance planning.
Instead of valuable information remaining within individual controllers, data can become accessible to engineering and production teams.
Integrating Legacy Equipment
Older machinery does not necessarily need to be replaced simply because a new SCADA system is being introduced.
Where technically appropriate, legacy PLCs and equipment can often be incorporated into a modern supervisory system using suitable communication interfaces or gateways.
This can allow organisations to improve operational visibility while developing a longer-term modernisation strategy for ageing equipment.
SCADA Integration with HMI Systems
SCADA and HMI systems perform related but different roles within industrial automation.
Individual HMIs can continue providing local machine control while SCADA provides broader supervisory visibility across multiple machines or production areas.
A well-integrated system allows operators to retain effective local control while giving production and engineering teams a wider view of plant performance.
Testing SCADA Integration
Every communication point and data exchange should be thoroughly tested before the integrated system enters production.
Testing may include:
• PLC communication verification.
• Tag validation.
• Data accuracy.
• Alarm testing.
• Setpoint verification.
• Network communication.
• Historical data recording.
• HMI and SCADA interaction.
• Functional testing.
• Site commissioning.
This ensures the information displayed within SCADA accurately represents the condition of the equipment in the field.
