Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operational Technology (OT) networks in industrial control and building automation face challenges in connectivity and maintenance as they age, especially with the need for enhanced cybersecurity, and there is a lack of integration with Ethernet-based Information Technology (IT) networks.
Innovation Solution
A pluggable module with a Single Pair Ethernet (SPE) interface that facilitates the connection of OT equipment to Ethernet-based IT networks, using a housing with a printed circuit board (PCB) and PHY devices for migration from standard SGMII to SPE protocol, enabling communication over a single twisted pair, and providing lightning surge protection and industry-standard compliance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If legacy OT technologies and protocols are used for industrial control networks, then specific industrial automation functions are achieved, but integration with Ethernet-based IT networks is limited and maintenance becomes increasingly challenging
Solution Approach 1:
The pluggable module implements a universal interface that combines both OT and IT network capabilities in a single device. The module accepts legacy OT protocols on one side while providing standard Ethernet interfaces on the other, enabling a single component to bridge multiple network types and eliminate the need for separate legacy equipment.
Solution Approach 2:
The pluggable module serves as an intermediary device between legacy OT networks and modern Ethernet-based IT infrastructure. It translates and adapts signals and protocols between the two systems, allowing seamless communication without requiring complete replacement of existing OT equipment or complex multi-protocol configurations.
2Adaptability or versatility
If standard Ethernet interfaces are used, then integration with IT infrastructure is simplified, but compatibility with Single Pair Ethernet protocols and long-distance industrial applications is limited
Solution Approach 1:
The module is divided into distinct functional segments with separate PHY devices dedicated to specific protocols. One PHY handles standard Ethernet traffic while another handles Single Pair Ethernet protocols, allowing each segment to be optimized independently while working together through the PCB interconnect architecture.
Solution Approach 2:
The module dynamically adapts its interface behavior based on the connected cable type and protocol requirements. The system can switch between different operational modes depending on whether standard Ethernet or Single Pair Ethernet is detected, enabling flexible protocol support without requiring manual configuration or fixed interface design.
3Reliability
If legacy OT network infrastructure is maintained, then existing industrial equipment continues to operate, but cybersecurity vulnerabilities and maintenance difficulties increase over time
Solution Approach 1:
The pluggable module acts as a security intermediary by introducing an isolated boundary between legacy OT networks and modern IT infrastructure. The module's architecture allows it to filter and control traffic between networks, blocking malicious payloads while permitting legitimate communication, thus protecting vulnerable legacy systems from direct exposure to internet-based threats.
