Setting Up, Understanding and Troubleshooting of Industrial Ethernet and Automation Networks

THE WORKSHOP:

Ethernet is fast becoming the obvious choice for automation networks worldwide. It is a rugged, versatile technology, equally at home in a chemical plant, on an ocean-going vessel and in the cockpit of a fighter aircraft. While the packet structure of Ethernet has not changed since its inception, technologies such as fast and gigabit Ethernet, industrial Ethernet, VLANs, redundant rings and real-time (deterministic) Ethernet for motor control applications have increased the complexity and choices available in planning and designing these systems.  As Ethernet has become more complex, a number of misconceptions have arisen as to how Ethernet functions and how the system should be optimally configured. This workshop addresses these issues in a clear and practical manner.

Ethernet can be easily augmented with wireless technologies, and the workshop takes a brief look at the current and emerging industrial wireless technologies such as IEEE802.11, wireless mesh and wireless sensor networks; how they function, and where they fit into the overall picture.

Ethernet is almost synonymous with the TCP/IP protocol suite. Because of its rugged design and the fact that it is Internet-compatible, all major automation system vendors are adopting TCP/IP (and, of course, Ethernet). This complex topic will be covered in an easily-understandable and coherent manner.

OPC has made vast inroads into the process automation arena and has been adopted by every single SCADA system vendor. We will look at current standards, in particular the DA standard, and also at new developments such as the ‘Unified Architecture’. We will also highlight some tricky implementation issues and ways to avoid the pitfalls. 

With regard to the automation arena there is a strong move to wireless and Ethernet/TCP/IP. We will look at the offerings of the HART communication foundation, the open DeviceNet Vendor Association, The PROFIBUS/PROFINET user organisations and the fieldbus foundation, as well as the latest Ethernet fieldbuses such as EtherCAT, EPL and SercosIII, to get an overall idea of the current trends. In particular we will focus on the real-time issue, a prerequisite for motor control applications. Real-time Ethernet can now operate at sub-millisecond access times and less than one microsecond jitter. We will look at the various offerings by the abovementioned vendors and the two basic methods through which this incredible performance is being achieved.

Finally we will look at every system manager’s nightmare, security, and will suggest some simple common-sense and internationally-accepted measures to keep the hackers at bay.
