Edge computing in SCADA in SCADA systems - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is edge computing in the context of SCADA systems?

Edge computing in SCADA means processing data close to where it is collected, like near sensors or machines, instead of sending all data to a central server. This helps make decisions faster and reduces network load.

beginner

Name one key benefit of using edge computing in SCADA systems.

One key benefit is faster response time because data is processed locally, allowing quick actions without waiting for central servers.

intermediate

How does edge computing improve reliability in SCADA systems?

Edge computing allows SCADA devices to keep working even if the connection to the central server is lost, because data processing and control happen locally.

intermediate

What kind of devices are typically used for edge computing in SCADA?

Devices like programmable logic controllers (PLCs), remote terminal units (RTUs), and small industrial computers are used to process data at the edge in SCADA systems.

intermediate

Explain how edge computing can help reduce network bandwidth usage in SCADA.

By processing data locally and sending only important or summarized information to the central server, edge computing reduces the amount of data sent over the network.

What is the main purpose of edge computing in SCADA systems?

A Increase data storage in central servers

B Send all data to a cloud server for processing

C Process data near the source to reduce delay

D Replace SCADA with manual control

Edge computing processes data close to where it is collected to reduce delay and improve response time.

Which device is commonly used for edge computing in SCADA?

A Remote Terminal Unit (RTU)

B Smartphone

C Laptop

D Cloud data center

RTUs are common edge devices in SCADA that collect and process data locally.

How does edge computing affect network bandwidth in SCADA?

A Increases bandwidth usage by sending more data

B Requires new network cables

C Has no effect on bandwidth

D Reduces bandwidth by processing data locally

Edge computing reduces bandwidth by processing data locally and sending only necessary information.

What happens if the connection to the central server is lost in an edge computing SCADA system?

A Local devices continue to operate and process data

B The entire system stops working

C Data is lost permanently

D The system switches to manual mode automatically

Edge computing allows local devices to keep working even if the central connection is lost.

Which is NOT a benefit of edge computing in SCADA?

A Faster decision making

B Complete elimination of central servers

C Reduced network load

D Improved system reliability

Edge computing complements central servers but does not eliminate them completely.
