2. Operational Technology (OT)
PLCs, HMIs and SCADA systems can communicate with each other via fieldbusses.
Here we are going to learn about the fieldbus protocols, which are connection protocols for multiple field devices.
What is a fieldbus?
Here you are going to learn what the fieldbus protocol types do and how they are able or unable to connect.
After watching this video, you should be able to distinguish the different topologies utilised and how connections are handled. It should also have shown you how the different protocols require different modules to interact.
