IT vs OT
Plant operations have evolved over time using generally well-integrated and well-applied digital automation technologies, such as distributed control systems (DCS), programmable logic controllers (PLC), safety integrated systems (SIS), and manufacturing ex*****on systems (MES). These plant-level technologies all fall under the domain of operations technology or “OT,” as distinguished from more enterprise-level information technology, or “IT”. In general, OT focuses on safe, deterministic, and high availability for reliable, nonstop operations, while IT focuses on data integrity and security.
