How does the PLC understand or know how to interpret the string of data that is received from the device and how to form the proper command string for the device.
The answer is the GSD File. GSD stands for “General Station Definition” and is a text file which allows the PLC to parse or interpret the incoming data stream from the device and to properly form a command string sent to the device. This file gives the device its identity or personality.
In addition, most Profibus DP devices provide a wealth of diagnostic data to help the engineer or operator keep the device operating reliably.
In all PLC and DCS systems, there is a prescribed way that GSD files are made available to the system. In this video, we will learn how to install a GSD File on a Siemens S7-series PLC system which is programmed by the Siemens STEP7 software.

In previous videos, you have learned how to configure a Profibus-DP network in STEP 7 and TIA Portal and how to install a GSD file using STEP7 version 5.6. Now, I will show you how to install a GSD file using TIA Portal.

In this lesson, you are going to learn how easy it is to configure a Profibus DP Network in TIA Portal.
In the previous lesson, you learned how to configure the Profibus DP port on a CPU using TIA Portal.
In this lesson we are going to continue discussing the Profinet-DP network software setup in TIA Portal.
