Industrial communication

The aim of industrial communication is the reliable transmission of data from the field through to the control level. Consistent solutions with Industrial Ethernet, state-of-the-art wireless technologies, and cybersecurity increase the availability and security of the networked systems here. The examples of industrial communication networks include Ethernet, DeviceNet, Modbus, ControlNet, and so on. The three significant control mechanisms used in industrial automation field include Programmable Logic Controllers (PLCs), Supervisory Control and Data Acquisition (SCADA) and Distributed Control System (DCS).

Industrial Protocols are communications protocols that ensure connectivity between machines, devices, and systems as part of an industrial network. Communication protocols enable industrial communication so managers can have greater visibility and control of their operations. Network communication, or internetworking, defines a set of protocols (that is, rules and standards) that allow application programs to talk with each other without regard to the hardware and operating systems where they are run.

In an industrial setting there are four basic levels of networking. These levels are: informational, control, device, and safety [1]. Each level has unique requirements that affect which network is used for that particular level.
