Course Description

This is the first in the series of protocol units to introduce learners to how the MODBUS protocol used in Industrial Automation to communicate with devices. Once you have completed this course you will be competent in understanding how to troubleshoot and connect devices on a MODBUS RS485 network. You will have the know-how to troubleshoot the MODBUS messages for errors on the network and to interpret them as well.

The MODBUS protocol is the oldest and still by far the most popular automation protocol in the field of process automation and SCADA. This course gives you theory behind the Modbus Protocol as well as RS485 networking. The course is only the RS485 networking component as a subset of our Communications and Network Topology on how MODBUS integrates into the overall control and management of plant equipment. After completing this course, you will be able to integrate devices that are Modbus compliant.
