IEC 60870-5 protocol in SCADA systems - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is the IEC 60870-5 protocol used for?

IEC 60870-5 is a communication protocol used in SCADA systems to exchange data between control centers and substations in electrical power systems.

beginner

Name two common parts of the IEC 60870-5 protocol.

Two common parts are IEC 60870-5-101 (serial communication) and IEC 60870-5-104 (network communication over TCP/IP).

beginner

What type of data does IEC 60870-5 typically transmit?

It transmits control commands, status information, and measurement data such as voltage, current, and frequency.

intermediate

How does IEC 60870-5-104 differ from IEC 60870-5-101?

IEC 60870-5-104 uses TCP/IP networks for communication, allowing faster and more flexible data exchange compared to the serial line communication of IEC 60870-5-101.

intermediate

Why is IEC 60870-5 important for power system automation?

It standardizes communication, enabling reliable and interoperable data exchange between devices from different manufacturers in power system automation.

What does IEC 60870-5-104 use for communication?

A TCP/IP networks

B Serial lines

C Bluetooth

D Wi-Fi

IEC 60870-5-104 uses TCP/IP networks for communication, unlike IEC 60870-5-101 which uses serial lines.

Which type of system commonly uses IEC 60870-5 protocol?

A Mobile apps

B SCADA systems

C Web servers

D Database management

IEC 60870-5 is designed for SCADA systems in electrical power automation.

What kind of data is NOT typically sent by IEC 60870-5?

A Video streams

B Control commands

C Status information

D Voltage measurements

IEC 60870-5 does not transmit video streams; it focuses on control and measurement data.

Which IEC 60870-5 part is designed for serial communication?

A IEC 60870-5-104

B IEC 60870-5-105

C IEC 60870-5-103

D IEC 60870-5-101

IEC 60870-5-101 is the part designed for serial line communication.

Why is standardization important in IEC 60870-5?

A To reduce power consumption

B To increase internet speed

C To ensure devices from different makers work together

D To improve mobile app design

Standardization allows devices from different manufacturers to communicate reliably in power systems.

Explain the main purpose and typical use cases of the IEC 60870-5 protocol in SCADA systems.

Think about how power systems need to send and receive data safely and reliably.

Describe the differences between IEC 60870-5-101 and IEC 60870-5-104.

Consider how older and newer communication technologies are used.
