This course, Communication system for data, is designed to provide engineers and technicians with an overview of modern communication systems for data – starting at the basic RS232 standard right through to Ethernet communication and beyond.

On successful completion of this course, delegates will be able to:

• Understand the basic principles of data communications
• Apply basic faultfinding techniques covering RS232 up to RS485
• Apply Modbus in a practical manner and make use of troubleshooting techniques
• Differentiate between the use of Modbus, Modbus Plus, ASI, DeviceNet, Profibus, and Foundation Fieldbus
• Understand the basics of Ethernet
• Understand TCP/IP and its associated protocols
• Apply some of the basic TCP/IP utilities

Designed for both novice and experienced engineers and technicians, this course starts at fundamental principles and progresses through basic coding and formatting systems, error detection, and protocols through to advanced fieldbus and device networking concepts.

Throughout the course, participants will learn through active participation using exercises and questionnaires covering:

• RS 232
• RS 485
• Modbus
• Ethernet Networking
• TCP/IP

What You Will Learn

• An understanding of the basic principles of data communications
