What does a systems integrator do in regulated manufacturing?

That is where an experienced systems integrator adds value.

What is a systems integrator in manufacturing?

A manufacturing systems integrator brings different technologies, platforms and operational systems together into a connected manufacturing environment.

Rather than approaching automation, data and digitalisation as separate projects, a systems integrator looks at how the complete technology architecture supports the manufacturing process.

This can include:

The objective is to create systems that are reliable today while also providing a scalable foundation for future manufacturing requirements.

What does a systems integrator actually do?

The exact scope will depend on the facility and project, but there are several areas where systems integrators play a particularly important role in regulated manufacturing.

Successful integration starts with understanding what is already in place.

Many established manufacturing sites contain technologies introduced over several decades. New platforms may operate alongside legacy PLCs, ageing control systems, different historian technologies and equipment supplied by multiple OEMs.

For example, a new production line may need to communicate with existing plant infrastructure while continuing to support older equipment elsewhere on the site.

The systems integrator provides the engineering expertise required to make these technologies operate as one coordinated environment.

Replacing every legacy system is rarely realistic.

Manufacturing facilities frequently contain equipment that continues to perform its operational role effectively but was never designed to integrate with today’s digital infrastructure.

The challenge is finding a reliable way to connect those systems without unnecessarily disrupting production.

A systems integrator can develop an architecture that allows manufacturers to modernise gradually by connecting legacy technology to newer control, data and analytics platforms.

This can help extend the useful life of existing assets while reducing the risks associated with large-scale replacement programmes.

For multi-site manufacturers, this can become particularly important when attempting to create common technology or data standards across facilities with very different installed bases.

Manufacturing organisations are generating more operational data than ever before.

The value of that information depends on whether it can be collected, structured, contextualised and made accessible.

These questions increasingly form part of wider digital manufacturing strategies.

Process historians often become some of the most important systems within a manufacturing facility.

They may support production reporting, investigations, process optimisation, batch analysis and regulatory activities.

As these platforms age, manufacturers may encounter unsupported operating systems, ageing hardware, outdated software versions or increasingly complex interfaces.

Historian upgrades can therefore involve considerably more than installing a new version of software.

A systems integrator may need to manage:

For regulated manufacturers, maintaining data integrity throughout this process is critical.

Réalta Technologies has delivered PI System upgrade programmes involving more than 50 interfaces, achieving zero data loss while completing validation within the required shutdown period.

That type of project demonstrates why historian modernisation requires expertise across engineering, infrastructure, data and compliance rather than treating the historian as an isolated software platform.

Historian strategy should also be considered as part of the wider manufacturing data architecture. Depending on the organisation’s requirements, this can mean integrating the historian with MQTT brokers, Unified Namespace environments, industrial data platforms and analytics tools rather than treating it as an isolated system.

The goal should not be connectivity for its own sake.

Every integration should have a defined operational or business purpose.

Regulated manufacturing introduces additional responsibilities that do not exist in many conventional industrial environments.

Technology changes may affect validated processes, electronic records, data integrity and regulatory compliance.

An experienced systems integrator must therefore understand requirements such as:

Compliance should be considered during design rather than added at the end of a project.

This is particularly important when upgrading critical manufacturing infrastructure.

Architecture decisions, testing strategies, documentation and project execution should all support the organisation’s validation requirements.

In regulated manufacturing, technical success and compliance cannot be separated. A system that performs technically but cannot meet validation or data-integrity requirements is not a successful implementation.

Connecting systems is only part of the challenge.

Which equipment conditions indicate an increased risk of failure?

How can engineers investigate deviations more quickly?

Once the required outcome is understood, the appropriate data architecture can be designed around it.

Artificial intelligence is becoming increasingly relevant across industrial operations, but AI effectiveness depends heavily on the quality and structure of the underlying operational data.

Manufacturers considering AI should first assess whether they have:

A systems integrator can help build these foundations before organisations move into more advanced AI use cases.

For many manufacturers, AI readiness is therefore not simply a question of selecting an AI platform. It requires a strong underlying architecture connecting automation systems, historians, Unified Namespace environments, MQTT brokers, data platforms and analytics technologies.

Without them, AI programmes can struggle to move beyond proof-of-concept projects.

Large manufacturing programmes frequently involve several disciplines simultaneously.

An automation upgrade could affect networking, servers, historian interfaces, validation, reporting systems and existing production equipment.

A systems integrator can therefore remain involved throughout the system lifecycle.

Support can include:

This lifecycle approach can help manufacturers identify risks before systems become obsolete or unsupported.

Why is systems integration particularly important in regulated manufacturing?

Regulated manufacturers face a combination of technical and compliance requirements that make system changes particularly complex.

Production systems need to be:

Reliable Manufacturing operations cannot tolerate unnecessary downtime.

Compliant Systems and processes must support applicable regulatory requirements.

Validated Changes to regulated systems need appropriate testing, documentation and traceability.

Secure Increasing connectivity must be accompanied by appropriate OT cybersecurity controls.
