Modern industrial control and information systems employ a proliferation of technologies, including various hardware standards and protocols. For many of the personnel working with these systems the technologies are 'plug and play' and are just there to be used. The problems arise when decisions have to be made regarding the most suitable technologies for a given application, or when things go wrong and troubleshooting has to be performed. Without a thorough grasp of the working of the technologies involved, and without the availability of (and the ability to use) suitable diagnostic tools, this becomes a formidable challenge.

The world of industrial communications abounds with three-letter acronyms, protocols, layered communication systems, fieldbuses and device networks. There are numerous networking and industrial bus standards, synchronous and asynchronous protocols, baseband and broadband systems, bus and star topologies, connection-oriented and connectionless protocols. In addition, there is a pronounced migration towards the use of Ethernet and TCP/IP. No wonder some of us are feeling a little confused.

To complicate matters, many technicians and electricians who were initially trained in process instrumentation or electrical maintenance are now expected to perform network maintenance - truly a major challenge. This program demystifies the jargon and places the most popular systems, technologies, hardware standards and protocols in an OSI (Open Systems Interconnection) perspective. It explains how these technologies operate and equips participants with the tools and skills to do basic hardware and protocol-related troubleshooting on both serial (RS-485) and Ethernet type networks.

Industrial data communications, networking and IT systems are key components of all modern plants and facilities and industrial infrastructure. Robust and reliable communications links are now critical in almost every industry. There are daily reports of viral and hack attacks on industrial computer systems and there is an extraordinary need for up-to-date training and education in these areas.

To address the shortage of well-trained industrial data communications, networking and industrial IT personnel, EIT has developed an Advanced Diploma in Industrial Data Communications, Networking and IT. The short courses that form part of EIT's professional development series are designed to provide students with critical knowledge and practical tools that can be immediately applied to the workplace. They are ideal to up-skill and/or cross-skill in a particular area or technology.

Typical subjects that are taught and researched in the EIT School of Data Communications and Industrial IT include: computer systems engineering, data communications and networking protocols and standards, troubleshooting systems, Fieldbus, DeviceNet, Ethernet, Radio telemetry systems, fiber optics, DNP3, 61850, routers and switches, SCADA, Modbus, programmable logic controllers, RFID tagging, industrial network security and programming.
