Description

Profibus DP is one the most heavily used protocols in the automation industry. Yet learning about it is a real challenge. You could do your best with Internet based research on the topic and you will still find that the information would be mostly high-level. You just would not be able to get down to the practical details.

That's the point of this course, to demystify Profibus DP once and for all, to give the full picture and to give you the information that you need to actually work with Profibus DP at a practical level. If you are looking for a job that involves Profibus DP, you are supposed to be able to handle yourself well in the interview after doing this course.

In this course, you will learn:

- The reason Profibus DP was designed.

- The hardware, cabling, connectors used to connect Profibus DP devices.

- The steps required to build a Profibus DP network.

- How to build and simulate a Profibus DP network using Siemens SIMATIC software.

- How to program a physical Profibus DP network that will be on my workbench.

- Diagnostics and Troubleshooting.

- Profibus DP protocol frames and messages.

and much more ...

I waited for this course for a long time, and yes it is as per my expectations. I cannot thank you enough for your efforts. All I can ask is to keep continuing to deliver more and more. I always thought that if there could be one addition to courses is that if you can refer book for more in-depth. Thanks once again.

Preview 02:21

An example diagram is used to illustrate the typical network layout and structure of a Profibus DP network. Similarities to a Modbus RS485 network are show to exist.

Typical Network Layout and Structure
02:58

Typically, the address of Profibus DP slave devices are set using hardware switches on the device itself. However, there are exceptions to this. The address of the Profibus DP master device is typically set through software.

Setting the Addresses of Profibus DP Devices
03:38

There are special reserved addresses that are used on the Profibus network.

Special Reserved Addresses
03:34

Number of start bits, parity and number of stop bits are standardized in Profibus DP. Baud rate is configurable.

Communication Port Parameters
02:39

The baud rate used is determined by the slowest device on the network.

Determination of Baud Rate on the Network

+ – The Step by Step Process of Building a Profibus DP Network
7 lectures 33:50

This lecture outlines the 7 steps that are used to create a Profibus DP network. Those same steps will be further expanded in the remainder of this section.

An Outline of the Steps to Create a Profibus DP Network
03:26

The profibus planning software is used to create a map of all of the slave devices on the profibus network, so that the master can use this information to communicate with the slave devices on the network.

The Role of the Profibus Planning Software
04:26

What a GSD file is, what it is for and how it is used. These topics are explored in this lecture.

Understanding GSD Files
06:23

We go to the site of an automation vendor and download a GSD file, open it and examine the contents.
