Industrial System Integration Services

DCS–PLC integration, OPC interfaces, Modbus and industrial Ethernet — connecting your automation ecosystem

Service Overview

Connecting Your Automation Ecosystem

Modern industrial facilities operate with multiple control systems, package units and third-party equipment from different vendors. NL Automation specializes in connecting these disparate systems through reliable, well-tested integration solutions — enabling seamless data exchange, coordinated control and unified operator visibility.

DCS–PLC Integration

  • DCS-to-PLC data exchange — analogue values, status signals and commands
  • Interlock coordination between DCS and PLC-controlled equipment
  • Redundant communication path design and failure handling logic
  • Communication health monitoring and diagnostic alarming
  • Data validation and cross-check logic for safety-critical signals

Communication Protocols & Interfaces

OPC DA / OPC A&E

OPC server/client configuration for real-time process data and alarm/event exchange between platforms.

Modbus TCP/RTU

Modbus master/slave configuration for package units, drives, meters and third-party instruments.

Industrial Ethernet

Industrial Ethernet and PROFINET communication for high-speed, deterministic data exchange.

Package Unit Integration

Third-party package unit and vendor-supplied PLC integration with the plant DCS.

Testing & Validation

  • Data mapping verification — tag-by-tag signal and value validation
  • Communication link FAT and SAT testing with formal evidence
  • Failure mode testing — link loss, timeout and fallback state validation
  • Communication diagnostic logic and troubleshooting procedures

Value to the Customer

Reliable system integration eliminates information silos, reduces manual intervention between systems and ensures operators have a complete view of the process from a single interface. Tested integrations reduce commissioning surprises and operational risk.
