Industrial Communication | Types of Fieldbus Protocols

Introduction: –

Industrial communication is a very important part of industrial automation. In this, you can find Industrial Communication | Types of Fieldbus Protocols.

In past decades growth of industrial automation rapidly increased and digital control strategy became more popular. That’s why standard communication protocols have started to be used in industries.

Fieldbuses are networks that combine hardware, software, and communication protocols for interconnecting field devices to controllers.

Due to the digitalization in the industry, high-performance Fieldbus networks need to transfer a massive amount of data efficiently and rapidly for the smooth operation of the plant.


Industrial Communication Levels

Industrial communication is divided into three main levels according to the given below.

  1. Plant Level
  2. Cell level
  3. Device Level

Different Communication levels in plants

1. Plant Level

This communication level is the final level of industrial communication. Plant level communication is responsible for transferring and receiving enterprises level communication data to lower levels of plants.


2. Cell Level

This layer transfers data from the device level to the plant level. At the cell level communication controllers are connected with some standard communication protocol.


3. Device Level

And This layer is all about communication between field sensors to controllers.

This layer is responsible for transferring process data and the status of the process to cell-level devices.



Categorization of Industrial Networks


All industrial communication network is divided into four parts: –

  • Field area network
  • Local area network
  • Wide area network
  • global are network

Levels of Industrial Networks

1. Field Area Network: –

Fieldbus is the network that is responsible for providing communication between sensors and controllers. different type of field area network protocols is used in the industry it’s called Fieldbus.

All field users follow standards decided by international organizations. And these are all listed below.


NoOrganizations
1International electrotechnical commission (IEC)
2International standard organization (ISO)
3European Committee for Electrotechnical Standardization (CENELEC)
4Instrumentation Society of America (ISA)
5American National Standard Institute (ANSI)
International communications standard providers.


Leading Internation standard in industrial communication area is provided by the International electrotechnical commission.

Fieldbus protocols Used in industry

IEC Certified protocols are mostly used in industrial communication. So, this is all about field area networks and different communication protocols used in field bus communications.

Communication Protocol used in higher-level is discussed in other posts so stay tuned for the next post.


2. Local area network

After reaching all-sensors data to control by using this Fieldbus communication protocol now all controllers are transmitted data through using Ethernet.

Now, most data are transferred by using Ethernet protocol as per the IEEE 802.3 standard.
