Types of Industrial Communication Networks
Many industrial businesses, such as manufacturing plants, warehouses, and construction firms, require expansive communication networks. These networks make it possible to store and transfer data, power automation equipment, and run control systems. While there is a variety of different types of industrial communication networks out there, the two most popular are LAN and WAN.
LAN
LAN stands for Local Area Network. These are used when a business’s communication network only exists locally. It is also an isolated network that only contains the data and processes it is provided. A LAN is ideal if a business does not need to communicate data with a more extensive network.
WAN
A WAN, or Wide Area Network, is a global system. This type of network allows businesses to use WANs to connect their data with other networks. WANs come in handy if a company has different branches, particularly if one branch is part of a larger company. Businesses that need to communicate with other networks would benefit from a WAN.
SCADA Systems
One popular type of industrial communication network is SCADA. This control system architecture stands for Supervisory Control and Data Acquisition. Many businesses choose to use SCADA systems for their operations because they can be connected to many PLCs (programmable logic controllers) and automated systems. SCADA is able to control and regulate all of these systems at once. Additionally, SCADA systems require little maintenance and allow businesses to control processes and devices remotely.
Other Industrial Communication Networks
In addition to SCADA, there are several other industrial communication networks. They include but are not limited to:
Ethernet
DeviceNet
Modbus
ControlNet
While these industrial communication networks operate similarly, each has its own unique benefits. DeviceNet, for example, allows businesses to manipulate devices out on the field. These devices may include switches, panel displays, and sensors. ControlNet uses Common Industrial Protocol to merge the feel of a peer-to-peer network with the speed of an I/O system. Finally, Modbus is an open system that is popular for an array of industrial control applications.
