PLC Communications

This module is intended to provide the student with an introduction to data communication using PLC systems and peripherals. The fundamentals of LANs and data communications are discussed using Windows platform and Rockwell hardware and programming software such as RSLinx. In addition, an introduction to ethernet and network switching is also presented as well as detailed descriptions of topology and the operation of token passing in a data highway. The module also provides an overview of transmission media, response time and the basic principles of proprietary networks including the seven OSI layers.
