Which Type of Data Communication Is Used for Industrial Processes?


Heather Bennett

When it comes to industrial processes, the type of data communication used plays a significant role in ensuring smooth operations and efficient workflows. In this article, we will explore the various types of data communication commonly employed in industrial settings.

Wired Communication

One of the most traditional methods of data communication in industrial processes is through wired connections. These connections offer reliable and secure transmission of data over physical cables. There are several types of wired communication used in industrial processes:


Ethernet is a widely adopted standard for wired data communication in industrial settings. It utilizes twisted-pair or fiber optic cables to transmit data at high speeds. Ethernet offers excellent reliability and is capable of handling large amounts of data, making it suitable for complex industrial applications.

Serial Communication

Serial communication involves the transmission of data bit by bit over a single wire or pair of wires. It is often used for simple and low-speed applications in industrial processes. Serial protocols such as RS-232, RS-485, and Modbus are commonly employed for connecting devices such as sensors, actuators, and programmable logic controllers (PLCs).

Wireless Communication

In recent years, wireless communication has gained traction in the industrial sector due to its flexibility and ease of installation. Here are some widely used wireless technologies for data communication in industrial processes:


Wi-Fi technology provides wireless connectivity within a limited range using radio waves. It offers high bandwidth and is suitable for applications requiring real-time monitoring or control. Wi-Fi can be utilized to connect various devices such as sensors, mobile devices, and supervisory control and data acquisition (SCADA) systems.


Bluetooth technology allows short-range wireless communication between devices. It is commonly used for connecting mobile devices, human-machine interfaces (HMIs), and other peripherals in industrial processes. Bluetooth offers low power consumption, making it ideal for battery-powered devices.

Industrial Protocols

In addition to wired and wireless communication technologies, there are specific industrial protocols designed for data communication in industrial processes. These protocols ensure compatibility and interoperability between different devices and systems. Some widely used industrial protocols include:


Profibus is a popular fieldbus protocol used for communication between various automation devices in industrial processes. It provides high-speed data transfer and supports both digital and analog signals. Profibus is widely adopted in industries such as manufacturing, automotive, and oil and gas.


Modbus is a serial communication protocol widely used in industrial automation. It enables the exchange of data between devices connected via serial lines or Ethernet networks. Modbus is simple to implement, making it a popular choice for connecting PLCs, sensors, and other industrial equipment.

  • In conclusion, choosing the right type of data communication for industrial processes depends on factors such as the required bandwidth, distance, reliability, and compatibility with existing systems.
  • Wired communication offers reliable transmission but may require extensive cabling infrastructure.
  • Wireless communication provides flexibility but may be susceptible to interference or limited range.
  • Industrial protocols ensure compatibility but may require additional configuration or hardware support.

Carefully considering these factors will help organizations select the most suitable type of data communication for their specific industrial applications.

We hope this article has provided valuable insights into the different types of data communication used in industrial processes.
