| This is a comprehensive book covering the essentials of SCADA communication systems focusing on
DNP3 and the other new developments in this area. It commences with a brief review of the
fundamentals of SCADA systems hardware, software and the typical communications systems (such
as RS-232, RS-485, Ethernet and TCP/IP) that connect the SCADA operator stations together.
A solid review is then done on the DNP3 and IEC 60870-5 protocol where the features, message
structure, practical benefits and applications are discussed. The book is intended to be product
independent but examples will be taken from existing products to ensure that all aspects of the
protocols are covered.
DNP3 is an open protocol developed by Harris Controls Division, Distributed Automation
Products in the early 1990s and released to the industry based DNP3 Users Group in November 1993.
Much of the material on DNP3 contained within this text is based substantially on the documentation
available from the DNP3 Users Group, with interpretation and presentation by the author. The author
has tried to identify cases in the text where material has been reproduced directly from user group
standards or other sources, and apology is offered if there are any inadvertent oversights in doing this.
This book provides you with the tools to design your next SCADA system more effectively using
open protocols and to draw on the latest technologies. |
