This course provides a thorough understanding of modern industrial data communication including basic communication principles, hardware interfaces such as RS232, communication protocols: ASCII-based protocol, Modbus and other industrial protocols in peer-to-peer or network environment.  The Course provides “hands-on” work experience in using communication protocols handshaking techniques for various modern smart instruments and devices.

Upon the successful completion of this course, participants will be able to:-

• Apply the latest technology of industrial data communications and telecommunications in accordance with the international standard, EIA-232, 422, 423 and 485
• Explain the inner working of proprietary PLC networks and the Local Area Network (LAN) topologies and protocols
• Compare media access techniques such as CSMA/CD, token passing and master/slave
• Describe design methods for LANs using Ethernet and identify the different Ethernet varieties and which are best for industry
• Apply the options for Ethernet hardware to avoid instant obsolescence and being locked in the past and describe the  Open Systems Interconnection (OSI)
• Discuss the structure of the telephone system impacts industrial networks  and the analog dial-up connections and modems standards
• Employ the LAN, WAN, Intranet, Internet, TCP/IP protocols, addressing and troubleshooting
• Describe Smart Instrument Systems such as HART and discuss the fieldbus protocols and configurations

This course is designed for personnel with a need to understand the techniques required to use and apply modern industrial communications and telecommunications technology as productively and economically as possible.  This includes electrical, control and instrumentation, SCADA and telemetry systems, process control engineers and supervisors, engineering managers, network administrators, field technical support staff and project management staff.
