Today’s industrial organizations thrive through connectivity. Staying on top of demand and optimizing production towards a more efficient and competitive solution by seamlessly sharing data across every system, from field level instrumentation to enterprise wide systems that can monitor and control plant operations.

As an inherent result, increased data flow through these networks has caused concern for industrial corporations about how much longer today’s industrial networks and devices will be able to cope with the increasing demand of information. More and more Industrial networking product designers are implementing Industrial Ethernet solutions that allow for increased bandwidth, noise suppression, and safety isolation to support the future industrial networks.

This article will delve into the main characteristics of industrial ethernet networks and illustrate key aspects of using Ethernet magnetics in industrial ethernet devices. We will also highlight two ethernet transformer industrial designer kits available from Pulse Electronics.

Design Challenges of Industrial Ethernet Networks

Although based on the same ethernet standard, designing and specifying industrial network components is more challenging than working with commercial networks, where cables are typically sheltered from hazards that can impact the integrity and performance of the networks components.

In commercial networks, components interface with low voltage devices while cables are often routed under the floor, through the ceilings or behind walls. Ethernet switches and other hardware are placed in special protected areas that ensure a stable and good quality power, controlled temperature and dust-tight environments.

Industrial networks present an entirely different reality. Components interface with devices that work over a broad range of voltages. Cables, switches and other network elements, integral to machinery automation, are in harsh and potentially hazardous environments for which standard ethernet products are not made to withstand.

Industrial automation faces an increasing number of Ethernet-enabled devices coupled with a need to integrate field devices and plant floor information with enterprise network communications. Sharing the same communication standard enables enterprise-wide visibility and information flow that provide new opportunities for collaboration between plant and business operations.

In turn, this allows more convenient access to real-time data from control and instrumentation that can lead to improved plant operations. Integrating manufacturing processes with Enterprise Resource Planning (ERP) systems can lead to better production planning and scheduling, quality tracking, delivery information as well as real-time inventory visibility and control. However, these capabilities also create a significant increase in data flow.

Key Aspects of Industrial Ethernet Networks

Industrial networks are all about reliability and being deterministic; this means having data transmitted and received both clearly and consistently without noise or perturbations on the signals. Coupling signals from devices that work with different power potentials presents a threat to the devices themselves, where a fault operation in one device can spread a high potential over the network, thus compromising other devices.

Having the adequate isolation level integrated to the networking interface of devices is perhaps the most critical aspect of industrial ethernet enabled devices, as it impacts directly the ruggedness of the network.

By nature, automation is constantly shifting towards better performance through new technologies, yet their adoption is gradual. Therefore, networks need to cope with equipment that operates on older or legacy networks; allowing for retro compatibility and sparing capacity for further developments while providing increased network performance is vital within the design of industrial network interfacing devices.

This means maintaining third party devices to keep them operative through their entire product life cycle, while at the same time managing an increasing data flow capability required from newer and future devices. Within this approach of adaptability, network interface design also entails broadening the electrical specifications of networking components to meet the different standards required from different communication protocols.
