Fieldbus isn’t really one thing but more of a collection of things. Fieldbus is a group of protocols that are used in the industrial arena.
The Fieldbus protocols have been standardized as IEC61158.
Prior to Fieldbus protocols, industrial controller systems were connected using RS232 serial communications.
As you know, serial communications allowed only two devices to communicate.
Whereas today, the Fieldbus connections are more closely compared to the typical Ethernet connections where you can connect multiple field devices to a single connection point that would then connect to the controller.
The connections to the Fieldbus components, with the exception of the field devices themselves, are single cable connections. This connection scheme may vary depending on the Fieldbus protocol that you are using.
This type of field device connection saves on wiring runs that would have to go all the way back to the controller.
As you can see, this type of device wiring would have many benefits when the distance is an issue.
As you can imagine, your controller system will need to have a communications module that will be able to establish communications with the field devices.
In the case of ControlNet, you would need a ControlNet module, Profibus would need a Profibus module, etc.

In this blog post, you’ll learn about the mindset that helped me getting a PLC programming job with NO experience. This is my personal experience as someone who searched for a job in this field and as an employer who reviews resumes and interviews candidates for a variety of projects. So let’s get started!
Electricity is produced by a diversity of energy sources, and different types of technologies. We all have, at some point, heard about fossil fuels, nuclear energy, and renewable energy sources such as hydroelectric power.According to the U.S. Energy Information...
Platinum 100, or Pt100, resistance temperature detectors are an important part of many process control installations. Accurate and repeatable measurement of temperature is a requirement for many processes, including heating and cooling, chemical reactions,...
