Cover Story
Network Software
Executive Editor Jim Montague explores how many of the routing, switching and gateway functions done by hardware-based components are being taken over by more purely software programs and how this is altering the industrial networking landscape yet again. The evolving role of SNMP-type or similar network sniffing tools is examined.
Wireless Networking
Controlling Interference
Industry has been heralding for years the coming onslaught of wireless industrial applications. But the plant environment offers many opportunities for interference to corrupt the signal. This piece examines one solution to controlling interference in a wireless-network application.

Bus Stop column by John Rezabek
In this issue’s Bus Stop column, John Rezabek explains how the advent of process buses like Profibus PA and Foundation Fieldbus have caused more people in the large process industries to become interested in the quick-connect concept. The whole family of pre-configured and factory-terminated cordsets has spurred a new generation of connections.
Parity Check column by Ian Verhappen
There has been much discussion about Ethernet and IP as the next stage in the evolution of industrial communications. One of the impediments to the use of Ethernet at the field level has been the need to pull two sets of cable—one for power and the other for communications—to the devices. Just like in the office where power over Ethernet (PoE) connects your IP phone, it is possible to do the same in the field—at least in theory. In this issue’s Parity Check, Ian Verhappen discusses why PoE is and isn’t being used for industrial networking.
