OPC NEXUS│An OPC Server Comparison Guide for Manufacturing SIs

OPC server market overview

Compare OPC Servers
for Industrial Multi-Vendor Integrations

The wrong OPC server can cost more than its license fee — especially in environments where multi-vendor legacy systems, regional support gaps, and rapid scale-up demands are the norm.
This guide compares trusted OPC server vendors by project type to help manufacturing system integrators in India shortlist options — from mixed PLC connectivity and multi-site monitoring to audit-ready plant data integration.

How many PLC vendors are running
on your shop floor?

OPC server multi-vendor environment

Siemens, Rockwell, Mitsubishi Electric, and Schneider: multi-vendor environments are now common on manufacturing sites. Each vendor uses different communication protocols, and the cost of individual integration keeps adding up.
An OPC server works as a translator between these devices, but the right product depends heavily on your site configuration.
To choose the right product, first clarify the conditions of the project in front of you.

Deployment Started:
2018 Austria
Company Business Type
Nittoku Europe GmbH Winding Machine Manufacturer and System Integrator
Challenges

Development Workload Increased with Each Connected Device

In multi-vendor environments, each piece of equipment has different communication specifications. Because all integration had been handled through scratch development, the same work was repeated for each project.

  • Communication interfaces had to be developed from scratch for each piece of equipment and each device, requiring significant time and cost.
  • Integration with customers’ MES and ERP systems also required custom development each time, putting pressure on project schedules.
  • Engineering resources that should have been used to improve the added value of winding machines were tied up in communication development.
Background

Rewriting Communication Code from Scratch Every Time Equipment Changed

Nittoku Europe GmbH sells winding machines to manufacturers in Europe and also provides end-to-end system integration for end users as a contract-based system integrator. The company provides systems that centrally manage data from its own winding machines, conveyors, and equipment used in upstream and downstream processes, while connecting that data with customers’ MES and ERP systems.

Outcome

Deployment Time Reduced by 3 Months: Engineers Freed to Focus on Core Work

Communication drivers for a wide range of manufacturers enabled smooth integration of existing equipment, allowing the company to deliver about 15 automation lines per year to customers. Freed from custom communication development, engineers were able to focus on their core work: improving the performance and functionality of winding machines.

Voice from the Floor

Communication Speed Improved by 30–50% in Actual Line Testing, and Support During Issues Was a Deciding Factor

"In addition to general-purpose protocols like Modbus/TCP and BACnet, it is equipped with proprietary communication drivers for major PLCs, robots, processing machines, etc. from various manufacturers, allowing for easy connection. Communication speed is 30-50% faster compared to other companies' products, achieving an overwhelming performance improvement compared to conventional systems."

-Peter Santner / Head of Electrical & Software Engineering

"When a problem of inaccessible data occurred during system implementation, the Takebishi support team quickly analyzed the situation, proposed appropriate solutions, and led us to an early resolution of the trouble. This flexible support was a very important point in our adoption."

Company Business Type
Faurecia Automotive parts manufacturer
Background

Growing Traceability Requirements Across a Global Site Network

Faurecia is a major automotive parts manufacturer with 330 sites in 34 countries. The company supplies a wide range of products, including automotive seats, interiors, and emissions control technologies, to global OEMs such as Mazda and GM.
As customer requirements increased, Faurecia needed to provide detailed traceability data, such as which parts were used in which vehicles and whether torque and angle values during installation were accurate.

Challenges

Data Existed, but the Collection and Integration Framework Could Not Keep Up

Plant-floor data existed, but the framework for collecting and distributing it lacked efficiency and scalability.

  • A mixed PLC environment involving Allen-Bradley, Modbus, and Siemens required individual connection work for each piece of equipment.
  • Integration with the proprietary MES “IJ Core” required custom development each time, putting pressure on project timelines.
  • With many sites, the same issues were repeated around the world.
Outcome

A Data Foundation Connecting the Plant Floor to Management

Faurecia adopted Kepware Server as the connectivity foundation for plant-floor PLCs and used IoT Gateway functionality to standardize data integration with its proprietary MES over REST/HTTP. Complex communication settings using OPC DA were no longer required, allowing MES developers to build systems with familiar protocols.
The transparency project timeline was significantly shortened. After a successful pilot in Brazil, Kepware Server was rolled out as a standard solution across North America, Asia, and Europe in 2016. This created an environment where the entire organization, from plant-floor operators to executives, could access data in real time.
