Managing Communication with RS-485
In the previous chapters, we learned how to communicate using various wireless technologies and hardware. However, there are times when communicating over wireless isn’t suitable because it would cause interference with critical hardware in the vicinity. In this chapter, we will learn about a communication technology that isn’t wireless and is popular in industrial settings.
In this chapter, we’re going to cover the following main topics:
- Introducing RS-485
- Introducing Modbus
- Communicating using RS-485 hardware
Let’s consider what we will need to complete the projects in this chapter.
Technical requirements
You will need the following items to complete the exercises in this chapter:
