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.
in this new course you’re going to learn how to do the Profibus setup in the software but before that, we’re going to review the hardware setup for Profibus-DP as well. I say “review” because I know most of you have already watched our YouTube video about Profibus-DP and how it works but since we’re going to get into the software setup this time, It’s helpful to “review” the hardware setup quickly again.
