Controls engineers need a variety of information on industrial networking infrastructure topics such as wire, cable, fiberoptics, connection options, wireless technology, signal transmission and conversion, network configuration and monitoring and device power options.

Industrial Ethernet components to be evaluated include managed and unmanaged switches, routers, gateways, segment repeaters, and monitoring and configuration software.

Industrial Networking includes integrating factory floor industrial networks and process plant floor networks with company enterprise networks.

Wireless networks are attractive in applications where the cost of running signal cable and wiring, power cabling, or both is unattractive.

Timely news, back-to-basics primers, feature articles, technical white papers and descriptions of the latest products provide valuable insights that can be used in designing and building machine controls.

Ethernet Enables The Smart Grid
Author: Bill Wotruba, Belden Industrial Solutions, Director of Networking and Connectivity Products
Posted: 02/23/2010
The electrical power generation, transmission and distribution system has survived for decades with limited intelligence. But the emergence of independent power producers, green power sources and new regulatory regimes is making it imperative to add smarts to the grid.

The grid receives power from a variety of conventional and green power sources. The grid then distributes this power to industrial, commercial and residential consumers. Power flowing into the grid must be matched with power outflows as closely as possible on a real-time continuous basis.

When power inflows and outflows don't match, voltage fluctuations occur on the grid. Excess demand lowers voltages, eventually to problematic levels. Power storage can address part of the problem by temporarily boosting power supplied to the grid, but storage is both technically challenging and very expensive. A better approach is to match power flowing into and out of the grid based on real-time information and control systems.

These real-time information and systems necessarily rely on wired and wireless communication networks, and the de facto standard for these networks is Ethernet. Various Ethernet protocols and attendant hardware including switches, routers and connectors form the power grid communication backbone.

This white paper will first show how the electric utility landscape has changed over the past few decades, necessitating the smart grid. It will then be shown how Ethernet-based Supervisory Control and Data Acquisition (SCADA) systems can be used to monitor and control power flowing into and out of the grid. Finally, it will be shown how Ethernet-based SCADA systems can be used to match power inflows and outflows to keep the grid stable.

TIA-1005 Industrial Ethernet Cabling Standard

The Effect on the 10/100 Industrial Ethernet Switch Performance.

The Anixter Infrastructure Solutions Lab wanted to determine what effect the new TIA-1005 industrial cabling infrastructure standard would have on the data throughput performance of real Ethernet data packets running between SmartBits test cards and various manufacturers' 10/100 Ethernet switches in a real-world simulation. The test included five (5) different IP20-rated switches and three (3) different enterprise rack-mounted switches using various cabling channels made from both Category 5e and Category 6 cabling components and connector pairs that are allowable under the standard. The premise also asserts that the effect of the cabling channel interference will also vary from port to port and switch to switch because of the variable transmitter and receiver functionality.

Cabling Requirements for Harsh, Industrial Applications
Author: Peter McNeil, Product Marketing Manager, L-com Global Connectivity
Posted: 03/24/2009
This white paper explains the difference between traditional commercial controlled environments and harsh industrial environments, as well as the type of cabling and interconnectivity products to specify when designing networks. Additionally this white paper includes information on the two popular standards for measuring and rating harsh environments, IP and NEMA.

OPC Bridging Transfers Data Between Industrial Automation Systems
Author: OPC Training Institute
Posted: 01/26/2009
Integrators frequently use OPC technology to connect one Industrial Automation system (PLC, DCS, SCADA, HVAC, etc) with another so data can be shared between the two systems. Because OPC technology is based on the Client/Server architecture, the challenge is that two OPC Servers cannot communicate with each other directly. A variety of vendors provide an intermediate software solution, generically called an “OPC Bridge,” to facilitate this sort of communication. This whitepaper discusses the concept of the OPC Bridge, the solution architecture, required software components, and various features to help Integrators differentiate between different OPC Bridge products.
