Core Competencies:

Adherence to Global Standards

Our programming philosophy is rooted in established, verifiable industry standards, ensuring maximum robustness, maintainability, and interoperability across global deployments.

  • IEC 61131-3 Compliance: Expertise in all mandated programming languages: Structured Text (ST) for complex algorithms, Ladder Diagram (LD) for discrete logic, and Function Block Diagram (FBD) for graphical control flow.
  • ISA-88 (Batch Control) & ISA-95 (Enterprise-Control Integration): Design and implementation of modular, object-oriented code structures for reusable Units and seamless vertical integration (MES/ERP layers).
  • NAMUR NE 107 Diagnostic Philosophy: Implementation of advanced fault diagnostics using standardised status classifications for effective HMI/SCADA alarm management.

Deep Technical Expertise

Technical Highlight

We utilise Source Control Management (SCM) (e.g., Git) for collaborative PLC project file versioning, ensuring full auditability and structured code development across disparate platforms.

System Integration & High-Speed Data Architecture

Our solutions focus on high-speed data integrity, secure vertical connectivity, and scalable industrial data architecture (IDA).

SCADA/HMI and Visualization

High-Performance HMI (HPHMI)

Design principles following the ASM Consortium guidelines, emphasising operator situational awareness, alarm rationalisation, and effective data presentation.

Data Aggregation

Seamless integration of disparate control systems into a unified HMI using platforms such as Ignition or centralised DCS (DeltaV, Experion PKS).

IIoT & Enterprise Integration (OT-IT Bridge)

Secure Protocol Conversion

Utilising industrial gateways and edge devices to convert proprietary PLC protocols (e.g., DF1, SRTP) into standardised IT protocols.

Data Transport

Implementation of MQTT (Sparkplug B) for efficient, stateful, and bandwidth-optimised data transmission to MES and cloud environments (AWS IoT, Azure IoT).

Cybersecurity

Segmentation of OT and IT networks and deployment of hardened control systems per IEC 62443 guidelines, with a focus on Defence-in-Depth strategies.

IIoT & Enterprise Integration (OT-IT Bridge)

We handle technically demanding applications requiring specialised algorithms and certified validation processes:

Motion and Robotics

Implementing synchronised motion control (e.g., CIP Motion, EtherCAT) and seamless integration with industrial robot controllers via a fieldbus.

Process Control Loops

Advanced PID control implementation, including cascade, ratio, and model predictive control (MPC) strategies for continuous processes.

Functional Safety Systems

Design, validation, and programming of certified safety PLCs (SIL 2/3, Category 3/4) to meet ISO 13849 and IEC 62061 standards.

Partner with Certified Automation Experts

We deliver functionally complete, technically validated, and fully documented control systems across all major vendor ecosystems.

Pioneering the future of engineering through digital transformation, grounded in culture of safety and resilience.
