OT technologies and protocols
- [Instructor] Operational technology encompasses a wide range of technologies and protocols that are used in industrial environments. In this segment, we'll outline key operational technology protocols and standards that include Modbus, PROFIBUS, Highway Addressable Remote Transducer, and OLE for Process Control. When we think about operational technology protocols, one category of communication protocols used are the fieldbus protocols. These protocols and technologies play essential roles in industrial automation and process control, facilitating communication and data exchange between various devices and systems in industrial settings. Let's talk about a few of the fieldbus protocols. Modbus is a simple, open communication protocol that allows communication between different industrial devices, such as sensors, remote terminal units, and PLCs. Modbus is known for its ease of implementation and compatibility with a wide range of devices. Modbus includes three main protocol types…
