What is industrial Ethernet?
Over the past few years the use of Ethernet communications has spread into every corner of the business environment. Today Ethernet is making its way onto the plant floor in versions commonly referred to as industrial Ethernet, a generic term that includes many specific Ethernet protocols. The lead protocol at the device level is Ethernet (Modbus® TCP), the standard offer of Schneider Electric.Industrial Ethernet value for critical applications
Industrial Ethernet is a technology designed to maintain control of plant production while continually monitoring processes. The use of industrial Ethernet provides device level and enterprise-wide data allowing the integration of production information with business systems. This valuable integration provides a view for resource planning by plant supervisors, business line managers and especially maintenance staff. Within industrial automation applications the use of industrial Ethernet also offers continuous monitoring and control of all critical machine functions, including but not limited to motor current, speed, faults and temperature. This level of monitoring using Ethernet communications can simplify energy management and process productivity.Benefits
• Monitor and configure systems remotely • Diagnostics provide predictive failure warnings and troubleshooting • Network cable eliminates bundles of hard-wired input/output (I/O) • Ethernet (Modbus TCP) is a widely accepted network standard • Intelligent MCCs reduce the total installation cost by up to 20% • Networking allows the removal, replacement and reconfiguration of MCC units without disrupting the running processSquare D

Ethernet in Model 6 Low Voltage MCC
Ethernet (Modbus TCP) is simply Modbus protocol over Ethernet utilizing TCP/IP. Modbus TCP benefits by
combining an open communication standard, over the most common physical network and universal network
standard. The architecture of Modbus TCP simplifies communication capability with existing serial Modbus
devices allowing integration of legacy devices while future proofing your enterprise.
In 2007, ODVA extended the Common Industrial Protocol (CIP) specification to provide compatibility of Modbus
TCP devices. Ethernet/IP originators that support the new Modbus integration will be able to control and access
both Ethernet/IP devices, as well as Modbus TCP target devices from the same application.
Ethernet Application
• A star topology with home runs from each communicating device to an Ethernet switch mounted in the equipment is recommended due to the compartmental design of the MCC. Manual or protective disconnection of a unit removes all power to any communicating components, leaving a daisy chain or ring topology susceptible to loss of large sections of the network. Equipment ordered with Ethernet cabling and switches provide a connected, tested and documented system from the factory ready for one customer connection. • Physical barriers in the vertical wireway are standard for each section providing physical separation and isolation between the Ethernet communication cable and power cables. The communication cabling solution follows NEC® Article 725, UL 845, UL 508 and UL 891, and is individually verified and tested. • The ConneXium™ family of industrial-rated Ethernet switches offers high reliability and increases network performance, flexibility and diagnostics. ConneXview™ Ethernet software tool can automatically discover and map your network and monitor its performance and detect, diagnose and resolve network alarms. • Ethernet switch units from 8 ports in 12 in. units to 72 ports in 24 in. units can be centralized or distributed within the MCC. • Managed and unmanaged Ethernet switches are available. Each Ethernet switch unit is powered via a 24 Vdc power supply separately mounted unit above the switch unit. Unmanaged switches are lower cost, plug-and-play with no configuration interface or options. Managed switches provide configuration interface for features like SNMP, port-speed, VLANs and IGMP snooping.Ethernet Features
• Fast Device Replacement (FDR), a service available with Ethernet, employs a central server to store the IP addressing and the operating parameters for the device. When a device is replaced, the server automatically configures the replacement device with the same IP address and operating parameters. FDR is available for TeSys® T and Altivar® 61/71 drives utilizing Modicon® Premium,™ Modicon Quantum™ and Modicon M340™ PLCs as servers.• Device embedded web pages provide real-time display of diagnostic and maintenance information available by viewing a web browser connected to the network without setup or configuration.
Performance and Features
• Industrial Ethernet is not only well suited for enterprise-wide monitoring, but its speed and supporting infrastructure make it perfect for use in critical process control applications. • Ethernet protocol boasts a fast and increasing data rate, from 10 Mbits/s to 100 Gbits/s, data rate and time synchronization standardization, and each generation is interoperable with the previous. • Along with speed, Ethernet has many desirable physical features, such as standard RJ45 port, fiber optic cabling solutions for long distance, intelligent managed switches, embedded web pages, M12 harsh environment connectors, power over Ethernet, redundancy and wireless. • Intelligent infrastructure components, such as routers, switches and firewalls, with incorporated management features, result in an efficient, reliable and secure system for your critical processes.Commonality
• Many “open” industrial communication protocols allow third-party devices; however commonality is most important to Ethernet’s value and growth. Ethernet is a standard feature offer for a large number of devices and growing. Greater equipment selection allows the user to focus on features and functionality throughout enterprise architecture. • A common protocol also allows users to take advantage of a broader skill base for configuration, installation, maintenance and troubleshooting. Readily-accessible training and support reduces the need for specialized personnel and expensive training.Flatness
• Device level Ethernet allows users to reduce or eliminate the need for dedicated gateways and costly infrastructure, leading to more flexible and simpler network architectures. • Availability of a single network technology enables ease of data transfer to higher-level systems throughout the enterprise over the same network. • Ability to communicate from the manufacturing system to the front-office simplifies energy and asset management.

®T Motor Management System
Tesys T Motor Management System, an intelligent overload for starter units can be directly connected to an
Ethernet (Modbus TCP) network for data acquisition and control. Users gain access to motor data variables and
system process control through “onboard” I/O. Functionality for over/under voltage, over/under current, ground
fault and phase failure/unbalance protection is included. In addition, when combined with PLC interwiring, this
module provides an independent data acquisition and control system.
The TeSys T Ethernet controller natively contains dual ports, and offers four options to obtain an unique
