In today’s manufacturing environments, data flows between an ever-growing number of systems. Distributed control systems (DCS), PLCs, packaged equipment, historians, HMIs, MES platforms, and analytics tools must all communicate reliably to support operations, quality, and decision-making. When those systems cannot exchange information efficiently, integration projects become more complex and more expensive.
Fortunately, the DeltaV OPC UA Client provides a simpler way to connect DeltaV with third-party systems, helping manufacturers reduce integration complexity while improving scalability and maintainability.
The Challenge of Industrial Connectivity
Most modern facilities rely on equipment and software from multiple vendors. A single production environment may include:
- Process control systems
- PLC-based skids and OEM equipment
- Utility systems
- Manufacturing execution systems (MES)
- Plant historians
- Data analytics platforms
Each system generates valuable information, but that information only creates value when it can be shared across the organization. OPC has long served as the industry standard for secure and reliable data exchange between these systems.
Historically, integrating DeltaV with external OPC servers often required additional middleware applications to manage communication between systems. While effective, this approach added software, configuration requirements, maintenance responsibilities, and potential points of failure.
A Simpler Approach
Beginning with DeltaV v14.3.1, Emerson introduced the OPC UA Client, enabling direct communication between DeltaV and OPC UA servers. This eliminates the need for separate OPC client software in many applications and streamlines overall system architecture.
The result is a cleaner integration path between DeltaV and third-party systems.
Organizations can often benefit from:
- Reduced software dependencies
- Simplified system architecture
- Lower maintenance requirements
- Improved scalability
- Faster integration of new equipment and systems
- Enhanced cybersecurity options through OPC UA security features
Reducing Complexity Across the Plant
Manufacturers are continually looking for ways to standardize operations and simplify support. Every additional software application introduces another component that must be maintained, updated, secured, and documented.
By enabling direct communications, the DeltaV OPC UA Client helps reduce architectural complexity and allows engineering teams to manage integrations within the DeltaV environment they already know.
This can be particularly beneficial when integrating:
- OEM skids
- Package equipment
- Utility systems
- PLC-based production assets
- Historian solutions
- Manufacturing information systems
Supporting Scalable Growth
As facilities expand and digital transformation initiatives mature, the number of connected assets continues to grow.
The DeltaV OPC UA Client is designed to support large-scale connectivity requirements and can communicate with multiple OPC UA servers while managing significant volumes of real-time data. This allows organizations to build connectivity strategies that can grow alongside operational needs.
Rather than creating separate integration architectures for each project, manufacturers can establish a consistent framework for bringing data into DeltaV and making it available where it is needed most.
Enhancing Cybersecurity
Cybersecurity remains a critical consideration for industrial environments. Modern connectivity solutions must balance accessibility with protection.
The OPC UA standard supports security features such as authentication, encryption, and certificate-based communications. These capabilities help organizations build secure connections between systems while supporting broader cybersecurity objectives.
Real-World Applications
The DeltaV OPC UA Client can be used in a variety of scenarios, including:
Package Equipment Integration
Connect OEM skids and packaged systems directly to DeltaV for monitoring, alarming, and operational visibility.
PLC Connectivity
Exchange operational data between DeltaV and PLC-controlled equipment to support coordinated production activities.
Manufacturing Intelligence
Provide access to operational data for historians, MES platforms, reporting solutions, and analytics applications.
Utility and Infrastructure Systems
Centralize information from utility systems and supporting infrastructure within the broader plant control environment.
Looking Beyond Connectivity
Successful digital transformation is not simply about connecting systems. It’s about creating an environment where information moves freely, securely, and reliably across the business.
The DeltaV OPC UA Client helps organizations achieve that goal by reducing integration complexity, minimizing software dependencies, and providing a scalable foundation for industrial connectivity. Whether integrating a single skid or building a plant-wide data strategy, the ability to communicate directly with OPC UA-enabled systems can simplify project execution and support long-term operational success.
Key Takeaway
The DeltaV OPC UA Client enables direct communication between DeltaV and third-party OPC UA servers, reducing the need for middleware applications while supporting secure, scalable, and maintainable system integration. For manufacturers looking to simplify connectivity and accelerate digital transformation initiatives, it provides a powerful native capability within the DeltaV ecosystem.
