OPC UA / OPC DA / MQTT / MODBUS / DNP3 / IEC61850 Data Integration

Kepware OPC DA / OPC UA Connectivity

Kepware is SPC’s primary platform for industrial device connectivity where a reliable, standardized communication layer is required between automation equipment and higher-level applications. It can consolidate data from multiple industrial protocols and expose it through standardized interfaces such as OPC DA, OPC UA, and MQTT.

OPC DA Connectivity

Many industrial facilities still operate reliable legacy applications based on OPC Data Access (OPC DA). SPC supports these environments while providing a practical migration path toward newer architectures.

• OPC DA server/client configuration and DCOM setup.

• PLC and RTU data acquisition, tag mapping, scan-rate and communication optimization.

• SCADA and Historian integration, troubleshooting, data-quality verification, and migration assessment.

OPC UA Connectivity

For new systems and modernization projects, OPC UA provides a secure and interoperable framework for industrial data exchange. SPC configures server/client communication, endpoints, certificates, authentication, namespaces, subscriptions, and security policies.

• PLC / DCS to SCADA or Historian

• PLC / DCS to MES and production applications

• Plant systems to centralized or enterprise data platforms

• Hybrid OPC DA and OPC UA architectures during modernization

Multi-Vendor Device Connectivity

SPC can integrate common industrial platforms and devices, including Allen-Bradley/Rockwell, Siemens, Schneider/Modicon, Mitsubishi, Omron, ABB, Honeywell, Yokogawa, industrial meters, flow computers, protection relays, packaged machinery, Modbus devices, DNP3 RTUs, and IEC-based systems.

Engineering considers polling frequency, tag grouping, timeouts, retry strategy, PLC loading, network utilization, and server performance to ensure stable communication without unnecessary load on control networks.

Standardized Industrial Data Layer

A centralized Kepware layer allows multiple applications to consume the same standardized data source instead of establishing independent connections to every PLC or device.

• PLC / RTU → Kepware → OPC UA → SCADA / Historian / MES

• PLC / RTU → Kepware → MQTT Broker → IoT / Analytics / Cloud

• PLC / RTU → Kepware → Enterprise applications through controlled integration services

Availability and Security

For critical applications, SPC can design redundant servers, communication paths, health monitoring, configuration backup, and recovery procedures. OPC UA certificates, user authentication, encrypted communication, and controlled network access are incorporated according to project requirements.

Cogent DataHub Integration

Cogent DataHub is applied when the project requires advanced OPC bridging, tunnelling, aggregation, or real-time integration between independent systems. It is particularly useful in facilities that must connect legacy OPC DA infrastructure with modern OPC UA applications without replacing all existing systems at once.

OPC Bridging and Tunnelling

• Legacy OPC DA Server → Cogent DataHub → OPC UA Client

• OPC UA Server → Cogent DataHub → Existing OPC DA Application

• Local DataHub → Secure tunnel → Remote DataHub → OPC Client

This approach can reduce DCOM complexity across computers, domains, firewalls, and network segments while supporting gradual modernization of distributed control and information systems.

Real-Time Aggregation

DataHub can aggregate multiple OPC sources and present them to central SCADA, Historian, MES, or analytics applications. SPC configures data mapping, update direction, transformation, quality handling, and communication behavior according to operational requirements.

OPC Router Integration

OPC Router is used when the integration requirement extends beyond basic industrial device communication and requires structured data exchange between OT systems and enterprise applications.

Database, MES, ERP, MQTT and REST Integration

• OPC UA → OPC Router → SQL Database for production, batch, downtime, quality, energy, and traceability data.

• MES / Database → OPC Router → OPC UA → PLC for controlled transfer of orders, recipes, product codes, or approved setpoints.

• OPC UA → OPC Router → MES / ERP / SAP for production confirmation and enterprise workflow integration.

• OPC UA ↔ OPC Router ↔ MQTT / REST API for integration with modern applications and digital platforms.

Platform Selection

For complex projects, the platforms can be combined—for example: PLC → Kepware → OPC UA → OPC Router → MES/Database, or Legacy OPC DA → Cogent DataHub → OPC UA → enterprise applications.

End-to-End Service Capabilities

• Existing system and communication architecture assessment

• Connectivity architecture design and platform selection

• Kepware, Cogent DataHub, and OPC Router implementation

• PLC, RTU, DCS, SCADA, Historian, MES, ERP, database, MQTT, and API integration

• Tag development, mapping, protocol configuration, redundancy, and performance optimization

• FAT, SAT, commissioning, troubleshooting, documentation, training, and lifecycle support

Our Engineering Approach

1. Assessment & Requirements

Review existing automation systems, OPC servers, networks, protocols, tag quantities, update rates, applications, cybersecurity requirements, availability targets, and future expansion needs.

2. Architecture Design

Define data sources and consumers, connectivity platforms, network paths, security boundaries, server requirements, redundancy, tag structures, and application interfaces.

3. Configuration & Integration

Install and configure drivers, devices, OPC DA/UA, MQTT, databases, APIs, data mapping, user access, and application connectivity.

4. Testing & Commissioning

Validate communication availability, values, timestamps, data quality, read/write behavior, recovery, restart behavior, performance, redundancy, and end-to-end application integration.

OT/IT Integration & Cybersecurity

SPC structures data exchange between operational and enterprise systems through controlled connectivity and middleware layers. Depending on project requirements, the solution may include OPC UA certificate management, authentication, encryption, TLS, firewall rules, network segmentation, DMZ architecture, restricted write access, service-account management, audit logging, and configuration backup.

Where applications only require monitoring, read-only communication paths can be implemented to minimize unnecessary control-system exposure.
