Definition
OT (Operational Technology) refers to the hardware and software that monitors and controls physical industrial processes - in the energy sector: SCADASupervisory Control and Data Acquisition - system for real-time monitoring and control of industrial processes. systems, protection relays, substations and control systems for power generation and grid operation. OT is distinguished from IT by its real-time requirements, safety criticality and long operational lifetimes (20–30 years). The convergence of IT and OT (IT/OT convergence) is a major trend in energy digitalisation.
