Understanding industrial networks
When two or more devices are connected for data exchange, it is referred to as a network. Each device in the network can be referred to as a node. Industrial networks consist of controllers (PLC, PAC, or DCS), field devices, PCs, and other industrial devices that are connected to share and exchange data. A node in an industrial network can be a controller (PLC, PAC, or DCS), field device (sensor/transmitter or actuator), HMI, server, or workstation. The nodes in an industrial network utilize a special protocol for communication and to automate processes in the industry.
