COM 401: Data Communications Fundamentals

Overview

COM 401 is designed for engineers in protection, automation, systems integration, and communications and for consultants who specify, design, test, or use communications systems in operational technology (OT) applications. This course covers fundamental principles and usage of serial, radio, and Ethernet data communications employed in industrial and utility power systems. The course also covers fundamentals of major utility protocols, including DNP3, Modbus, Mirrored Bits communications, IEC 61850 GOOSE, and IEC 61850 MMS.

You will learn the terminology, concepts, and other information necessary to be knowledgeable in data communications. You will also learn the basic guidelines for the design, integration, and use of data communications equipment, protocols, and systems.
