In this new course what you’re going to learn is to how to configure a Profibus-DP network in both STEP7 version 5.X and TIA Portal.
When you’re going to create a Profibus DP network, there is a hardware setup and also a software setup.
Hardware setup is taking a Profibus cable which is a usually in form of an RS-485 cable and connect your PLC to the remote station or the remote I/O that you have on the field.
Software setup, on the other hand, is configuring a Profibus-DP network in the software so that your PLC and the remote I/O station can actually talk to each other.
The whole idea of using Profibus-DP is to decentralize the network between the PLC and the field devices. That’s where the DP comes from. DP stands for Decentralized Peripherals.
Profibus-DP is here to help you, as a PLC programmer, to decentralize the network between the PLC and the field devices. By field devices, I mean the sensors and actuators that you have in the field or on the factory floor.
