opcua

One open standard, connecting every machine, vendor, and platform on your floor.

INGSOL designs and implements OPC UA architecture for factories and manufacturing plants, giving PLCs, SCADA systems, MES platforms, and cloud applications a secure, vendor-neutral way to exchange data, without locking your plant into a single manufacturer’s ecosystem.

What OPC UA Is, and Why It Matters

OPC UA, short for Open Platform Communications Unified Architecture, is an open, platform-independent standard for industrial data exchange. Unlike its predecessor, OPC Classic, which depended on Windows-specific technology and offered limited security, OPC UA was built from the ground up to run on any operating system, carry rich, structured information rather than raw tag values, and secure that information with built-in encryption and authentication.

For manufacturers, this matters because equipment from different vendors, PLCs, drives, sensors, historians, rarely speaks the same proprietary language natively. OPC UA gives all of it a common, secure way to communicate, which is why it has become the default choice for structured, system-to-system communication in modern industrial environments.

What Our OPC UA Implementation Covers

OPC UA Server & Client Deployment

Configuring OPC UA servers on your machines and control systems, and OPC UA clients on the platforms that consume that data, MES, SCADA, historians, or cloud applications, so information flows in both directions reliably.

Legacy System Integration

Connecting older PLCs and control systems that do not natively support OPC UA through gateway devices and protocol converters, bringing legacy equipment into a modern data architecture without requiring replacement

Information Modeling

Structuring your plant’s data into OPC UA’s semantic information model, so a temperature reading, a batch ID, or a machine state carries meaning and context, not just a raw number.

Secure Architecture Design

Implementing OPC UA’s built-in security model, encryption, authentication, and certificate management, aligned with your broader OT cybersecurity requirements.

SCADA, MES & Cloud Connectivity

Using OPC UA as the connective layer between your control systems and your MES, historian, and cloud platforms, feeding the Data & Intelligence layer with structured, trustworthy information.

OPCUA vs. OPC Classic vs. MQTT

Manufacturers often ask which protocol they actually need. The honest answer is usually more than one, each suited to a different part of the architecture:

Factor	OPC UA	OPC Classic	MQTT
Platform	Platform-independent	Windows-dependent (DCOM)	Platform-independent
Security	Built-in encryption & authentication	Limited, relies on network-level security	Depends on broker configuration
Data Modeling	Rich semantic information modelingRich semantic information modeling	Basic tag-based data	Lightweight, minimal structure
Best Suited For	Structured, information-rich system-to-system communication	Legacy Windows-based industrial systems	High-volume sensor data, remote/bandwidth-constrained links

Vendor Neutrality Protects Future Choices

OPC UA works the same way regardless of vendor, which means your plant is never locked into a single manufacturer's proprietary ecosystem.

Structured Data Reduces Integration Work Later.

Because OPC UA carries structured, meaningful data rather than raw tag values, downstream systems like MES and analytics platforms can use it with far less manual mapping.

Security Is Built In, Not Bolted On

Encryption and authentication are part of the standard itself, not an add-on that has to be configured separately or is easy to overlook.

One Standard Scales From a Sensor to the Cloud

The same OPC UA architecture that connects two machines today can scale to connect an entire plant, or multiple sites, tomorrow

How INGSOL Delivers SCADA Systems

1. Assess Current Systems

We review your current PLCs, SCADA, and systems to determine OPC UA readiness and identify equipment that will need a gateway or converter.

2. Design Architecture

We design the server/client architecture, information model, and security configuration suited to your plant and planned expansion.

3. Deploy.

OPC UA servers, clients, and gateways are deployed and configured across your production environment.

4. Validate Data Flow

We validate that data is flowing accurately and securely between machines, SCADA, MES, and any cloud platforms in scope.

5. Document & Handover

Configuration is documented and your team is trained to manage and extend the OPC UA architecture going forward.

Why Manufacturers Choose INGSOL for OPCUA

Engineering-Led Implementation

Our engineers understand both the OPC UA specification and the industrial equipment it connects to, not just the protocol in isolation.

Built to Fit the Bigger Picture

We design OPC UA architecture as part of your broader Communication & Integration and Data & Intelligence strategy, not as an isolated technical exercise.

No Equipment Left Behind.

Legacy PLCs and control systems are brought into your OPC UA architecture through gateways, not treated as a reason to replace them

Purpose-Built Not Overbuilt

Part of a Larger Communication & Integration Strategy

OPC UA implementation is one component of INGSOL’s broader Communication & Integration pillar, which also covers industrial network design and SCADA/IIoT platform modernisation. OPC UA typically works alongside other protocols, MQTT for lightweight, high-volume sensor data, for example, rather than replacing them outright. Our team designs the right combination for your specific architecture.

Built for Factories Across Industries

OPC UA implementation is not specific to one type of equipment or sector. The same architecture and security model applies whether you are connecting extrusion lines, compressors, curing presses, CNC machines, or continuous process equipment. What changes is the specific information model and the systems on either end; the underlying standard and INGSOL’s implementation approach stay consistent.
