MODULE DETAILS

 

Module 5: TCP/IP and VoIP

 

Nominal duration: 5 weeks (40 hours total time commitment).

 

This time commitment includes the preparation reading, attendance at each webinar (1 hour plus 15-30 minutes for discussion), and the time necessary to complete the assignments and further study

 

MODULE PURPOSE

 

The Internet has made a substantial impact on the way we do business, as well as on the plant and factory environment. A superb suite of protocols inherited from the Internet is TCP/IP, which is used by many present-day automation and process control systems, SCADA systems and PLCs. Even low-level instruments are using TCP/IP and Ethernet to transfer information. TCP/IP and Ethernet are truly open standards, available to competing manufacturers and providing the user with a common standard at low cost. Another significant development is ‘convergence’. Over the past decade, networking and telephony technologies have converged to such an extent that one can transmit data, voice, fax and video over the same IP network. This module also addresses the basics of, and protocols used for, Voice over IP or ‘VoIP’.
