About This Chapter
Network Protocols in Industrial Networks - Chapter Summary
Network protocols describe ways of sending and receiving information on a network. Within this chapter, you will learn how these protocols can be applied to industrial networks. The lessons are informative and engaging, and you can take quick quizzes after each lesson to be sure you've mastered the material. When you've finished this chapter, you'll be able to:
- Describe how data is sent and received over a network
- Explain the different types of internet protocols, including Ethernet and Profibus
- Discuss the protocols used in critical infrastructure
- Define several specific protocols, including Modbus, ICCP, Tase.2, and others
- Tell about how the DNP3 protocol is used in SCADA
- Recognize object linking and embedding
- Identify advanced metering infrastructure
- Utilize network protocol simulators
1. OSI Model: Using Open Systems Interconnection to Send and Receive Data
The Open System Interconnection (OSI) model describes how data is sent and received over a network. It consists of seven layers: the physical layer, data link layer, network layer, transport layer, session layer, presentation layer, and application layer. This lesson discusses how the OSI model works and the role of each layer for transmitting messages.
2. What is a Network Protocol? - Types & List
Network protocols. You use them every day. Some even every minute, yet most people wouldn't know it. Network protocols are simply the rules the internet lives by. In this lesson, we'll learn what network protocols and look at the different types.
3. Ethernet Standards & Frames
In this lesson we will examine and understand the different Ethernet standards that govern LAN Technology. We will understand the differences in technology employed for twisted pairs wires, Ethernet links and Fiber Optics. We will also understand the components of an Ethernet frame.
4. Industrial Network Protocols in Critical Infrastructure: Definition & Overview
In this lesson, you are going to learn about the different types of network protocols used in the design and implementation of critical infrastructures.
5. Modbus Protocol in Industrial Networks: Definition, Applications & Equipment
In this lesson, we will define the Modbus protocol and its application in industrial networks. We will also describe equipment that uses/supports Modbus. We will conclude with Modbus TCP and how it is integrated with Ethernet protocol.
6. Inter-Control Center Communications (ICCP) & TASE.2 Protocols: Definition & Uses
The Inter-Control Communications Protocol is an international standard for power utility control centers. In this lesson, we will dive into the protocol definitions, functionality, and place in the OSI Model.
7. Distributed Network Protocol (DNP3) in Remote Systems: Definition & Components
In this lesson, we will discuss DNP3 and the layers that comprise it. We will review each layer's purpose in the communication process. Additionally, we will briefly discuss the DNP3 object library.
8. Object Linking and Embedding (OLE) for Process Control (OPC): Standards & Application
By the end of this lesson, you will be able to define and understand the meaning of Object Linking and Embedding (OLE) for Process Control (OPC). You will learn the different standards that are based on OPC and the technology each uses to enable the exchange of data. Also, you will learn how these standards are applied in industrial networks.
9. Industrial Network Protocols: Ethernet, Profibus, EtherCAT & Ethernet Powerlink
In this lesson, you will learn about different protocols used in industrial networks. We will start with defining what protocols are and then will discuss the different kinds used in industry.
10. Advanced Metering Infrastructure (AMI) & the Smart Grid: Composition & Security Issues
In this lesson, we will learn about advanced metering infrastructure and its components. Additionally, we will discuss some of the security issues involved in AMIs and ways to resolve them.
11. Industrial Network Protocol Simulators: Types & Uses
Before using actual hardware, it is sometimes useful to design and test network layouts in a controlled environment. One way to do this is to utilize network simulators, and in this lesson, we will cover several types of simulators and their uses.
