The Industrial Networks solution includes the design and implementation of communication infrastructure intended for supervision, automation, and control of industrial and utility processes in high-availability environments.

The architecture is structured to ensure deterministic communication, resilience to industrial conditions, interoperability between operational technologies, and secure integration with supervisory and corporate layers.

A3A Engenharia de Sistemas develops each solution based on process criticality analysis, operational communication flows, industrial protocols, and cybersecurity requirements, ensuring reliable support for continuous operation.

SCOPE OF WORK

Within the scope of Industrial Networks, A3A Engenharia de Sistemas can operate in the following areas:

Planning and Architecture

  • Survey of industrial assets and communication requirements
  • Definition of topology for control, supervision, and redundancy

  • Planning of segmentation between OT and IT layers
  • Sizing of resilience and environmental protection criteria

Deployment and Integration

  • Installation and configuration of industrial switches and communication devices
  • Implementation of redundant rings and resilient topologies
  • Integration with PLCs, RTUs, HMIs, and supervisory systems
  • Segmentation and access control between process domains
  • Technical supervision of activation in operational environments

Validation and Monitoring

  • Communication latency and deterministic behavior tests
  • Validation of redundancy and failover scenarios
  • Monitoring of network assets and industrial links
  • Consolidation of technical documentation and as-built records

Evolution and Optimization

  • Expansion to new plants or production areas
  • Refinement of network segmentation and resilience
  • Adaptation to new automation and digitalization requirements
  • Integration with broader OT cybersecurity strategies
