SCADA stands for Supervisory Control And Data Acquisition and is a kind of Operational Technology (OT).
RTU: Remote Terminal Unit
RTU stands for Remote Terminal Unit which is an Operational Technology (OT) device. It is a similar device to a PLC, but is developed for specific purposes. RTUs can often be found as part of telemetry systems within industry.
PLC: Programmable Logic Controller
A Programmable Logic Controller (PLC) is a type of Operational Technology which essentially takes signals (e.g. from sensors or from a human command) and sends a signal (e.g. to an actuator such as a robotic arm or a manufacturing line). These devices are programmable for a variety of functions.
OT: Operational Technology
OT, or Operational Technology, is any technology which provides “on-the-floor” operations. These are typically automation technologies, and includes:
Robotics
Dot by Awen is an asset (aka device) and vulnerability discovery system for Operational Technologies, and works in all kinds of industries.
IED: Intelligent Electronic Device
An IED, or Intelligent Electronic Device, is a type of controller device used in the electricity sector.
ICS: Industrial Control System
ICS is the acronym for Industrial Control System, which is a type of Operational Technology (OT) used in a variety of industries including Critical National Infrastructures and other automated manufacturing organisations.
ICS is sometimes referred to as Industrial Process Control Systems (IPCS).
IoT: Internet of Things
The Internet of Things (IoT) is a general term for the/a distributed network of devices typically used for the sensing and analysis of the physical world. IoT devices include smart home appliances such as personal assistants (including Amazon Echo and Google Home), “smart light bulbs,” “smart thermostats” and “smart meters.”
A subset of IoT is Industrial IoT, or IIoT, which is IoT for industrial sectors.
IIoT: Industrial Internet of Things
IIoT stands for Industrial Internet of Things, it is a flavour of IoT for the specific requirements of industrial sectors. Typically IIoT is used for the analysis of operational efficiencies and equipment maintenance, although it can also include all aspects of digitalisation of production lines.
