College of DuPage - OCC 128(a,b)
Industrial process control networks allow the sharing of resources and
information among the elements of a manufacturing or distribution process
much the same way that traditional LAN's increase the productivity of front
office and back office operations. The elements of such a network, the type
of data that is transmitted, the protocols that are used, and the
applications that are run have significant differences, however.
This talk will describe the various component parts of an industrial
control network, network hierarchies and architectures, and the unique
requirements that make control networks different from a typical office
LAN. The strengths and weaknesses of protocols such as HART, Modbus,
DeviceNet, Profibus, Foundation Fieldbus and Ethernet/IP will be discussed,
as well as the roles DCS, SCADA and enterprise-wide systems play in an
overall factory automation system.
Bill Latura is a Project Manager with the Automation Research group at
Ondeo Nalco in Naperville, IL. He spends his time designing and
implementing process automation systems, and developing cost-effective
methods of process data collection, including the use of 802.11b, infra-red
and Bluetooth wireless. He is also the system administrator for a Linux box
being used as a file and internal Web server running Apache and SAMBA. Bill
has been working with PC's in one form or another since the early 80's.
Currently his home network include four boxes running a combination of
Linux and Windows 2000 connected via fast Ethernet.
Bill's first exposure to Linux was in the pre-1.0 kernel days of 1993. He's
been a Red Hat fan since summer '95, though he has also worked with the
SuSE, Slackware, Debian and Caldera distributions.
Bill has been the Treasurer of UniForum Chicago for the past six years.
