Troubleshooting Industrial Ethernet & TCP/IP Networks

THE WORKSHOP

This workshop is a practical workshop devoted to two days of hands-on faultfinding and troubleshooting. After an initial familiarisation session on industrial Ethernet and TCP/IP the two days is devoted to practical hands-on exercises. The workshop has been structured to cover key issues in troubleshooting TCP/IP and Ethernet in detail, while going through the practical implementation of TCP/IP in office and industrial networks and the practical use of the Internet and Intranets. Troubleshooting and maintenance of TCP/IP networks and communication systems in an office and industrial environment are also covered.

15 practical mini-sessions expose you to typical problems that could occur with industrial Ethernet and TCP/IP networks and shows you how to fix them. Most of each day comprises practical sessions with a modicum of discussion to explain the key points. There will be a minimum of two people to a PC so that the practical component will be emphasised. At the end of this workshop you will walk away with a solid knowledge on troubleshooting industrial Ethernet and TCP/IP networks.
