This course covers the essential elements of SCADA systems with particular emphasis on the DNP3 protocol, with an overview of the IEC 60870.5 and IEC 61850 protocols as well as new developments in this area.


The course commences with a review of the fundamentals of SCADA systems hardware, software and the communications systems that connect the outstations to the SCADA Master control station. The R S-232 and RS-485 interface standards are reviewed, along with MODBUS, Ethernet and TCP/IP protocols. The application of both Local Area and Wide Area networks for SCADA system communications is also covered. A detailed explanation of the DNP3 protocol is given, where the features, message structure, practical benefits and applications are discussed. The course is intended to be product independent but examples will be taken from existing products to ensure that all aspects of the DNP3 protocols are covered.


Examples are given of the configuration issues for DNP3 operation over both low speed serial (eg Radio links) and high speed LAN and WAN networks. An overview of the IEC 60870.5 and IEC 61850 protocols and their areas of application is given as well as new developments in this area. The application of Fieldbus protocols in SCADA systems is also covered. This course provides you with the tools to design your next SCADA system more effectively using DNP3 to draw on the latest technologies.

How can an e-learning course be interactive?

Boredom can be a real danger, however, we use an interactive approach to our e-Learning – with live sessions instead of recordings.  The webinar software allows everyone to interact and involves participants in group work; including hands-on exercises with simulation software and remote laboratories where possible.  You can communicate with text messages, or live VoIP speech, or can even draw on the whiteboard during the sessions.
