Dive into the world of RS-485 communication networks! Learn how to build, maintain, and troubleshoot these essential systems in plant automation.
This course is all about making you comfy with RS-485 communication networks. You'll learn how to build and troubleshoot them, and we’ll even have some fun with hands-on activities!
Learn how to Build, Maintain and Troubleshoot RS485 communication networks
RS-485 is the de facto workhorse of data communications in the field of plant automation.
It is very effective in applications with significant electrical interference (noise) requiring a long transmission distance. Thus, the standard is often used in industrial applications. It is as an inexpensive local area network (LAN) connection that allows multiple receivers to connect within a multi drop configuration. RS-485 does not include a communications protocol.
This course delivers the theoretical and practical aspects of RS-485 in a very effective way, so that at the end, you will be able to build, maintain and troubleshoot any RS-485 based network in the plan automation field. The course features a live physical connection between a PLC and a Computer via a USB-to-RS485 converter, an example that is key to effective troubleshooting of RS-485 systems.
After completing this course, you will be able to integrate devices from the same manufacturers and different manufacturers, that are RS-485 compliant, to form a complete seamless network.
Be aware of the two areas of consideration for RS485 communications
Understanding of communication port parameters
Understanding of cabling standards

I have been working in the fields of Software Development, Software Systems Integration and Process Automation since 1996. In 2003, I stepped out on my own and started working for myself providing software development and systems integration services to small and medium businesses. I am also associated with a great company called Mora Systems Limited that under the leadership of...
Not that detailed information
This course is very comprehensive, but is geared to someone with know knowledge of serial transmission. It explains start, stop, and data bits, how asynchronous clocking differs from synchronous clocking, single-ended vs differential transmission, why twisted pair is effective in noise reduction, and finally getting to how two-wire RS-485 works. (I was a bit disappointed that it did not mention the less common 4-wire RS-485.)
If you are familiar with RS-232 and asynchronous serial transmission, and just wanted to know how RS-485 differs from RS-232 or RS-422, you will find this course much too basic. If, on the other hand, you have not worked with RS-232, this course will tell you lots of stuff that you need to know.
Really Informative. Gained lots of Knowledge about RS 485
Good introduction to RS485
great job...very detailed
I felt that that every lecture was structured in a clear and concise manner. Each lecture felt pertinent to the subject and I have found the examples used very practical and this has helped my understanding of serial communications and made me more confident and enthusiastic at work.
good content and easy language to understand.
thankyou,
Really Informative. Gained lots of knowlede on RS485 communication. Thank the tutor for giving clear explanation.
Till now , I am understanding it , that itself is great appreciation. Concepts defined clearly.
