SCADA and ICS

Information Technology (IT)

includes computers, servers, networks, and cloud platforms

Operational Technology (OT)

communications network designed to implement an ICS

“think about technology that interacts with the real world”

• OT involves ICS and SCADA

Industrial Control Systems (ICS)

provides the mechanisms for workflow and process automation by controlling machinery using embedded devices

• multiple ICSs can create a distributed control system (DCS)

Fieldbus

digital serial data communication protocol used in OT networks to link different programmable logic controllers (PLC)s

• used by ICS

Programmable Logic Controller (PLC)

type of digital computer used in industrial settings that enables automation and assembly lines, autonomous field operations, robotics, and other applications

• programmed with an HMI

Human-Machine Interface (HMI)

can be a local control panel or software that runs on a computer

Supervisory Control and Data Acquisition (SCADA)

type of ICS used to manage large scale multi-site devices and equipment in a geographic region from a host ccomputer
