Designing a Robust and Reliable Industrial Communications Infrastructure

  • by Bill Wotruba
  • October 12, 2007
  • Opinion

Industrial plants rely heavily on their automation, instrumentation and control data communications to relay signals between machinery, devices and control systems to activate events on an exacting and pre-determined schedule, with little or no margin for error. Plant managers and control network administrators also require optimal security, manageability and reliability so that network availability attains 99.999 percent uptime or better. Yet analysts report that a large percentage of unplanned downtime in industrial operations is caused by network infrastructure problems.

A Growing Ethernet Challenge on the Plant Floor

There is a growing challenge on the plant floor if you haven’t experienced it yet, I am sure you will soon. A study by ARC predicts that the number of factory floor devices with an IP address is going to TRIPLE in the next four years and those devices are pushing lower and lower into the controls architecture… from systems, to sub-systems down to sensors… so Ethernet equipment with an IP addresses are increasing rapidly.

OPC Consideration for Network Security

Multi-Segment Ethernet Networks

  • by Contemporary Controls
  • August 4, 2002
  • Feature

The maximum length of a 10BASE5 segment is 500 m and this would represent the network diameter of the Ethernet network if no repeaters were used.  However, Ethernet can be expanded to a larger network diameter by using repeaters as long as the network diameter does not exceed the collision domain of Ethernet.  This article will discuss those restrictions.
