Communications enables the exchange of data between devices on an industrial control network. Without communications, controllers are unable to see the values coming from field devices, and operators are unable to see the values coming from controllers. Here are some of the key terms we will use while talking about industrial networking and communications:
Media: Communication requires wires, cables, or fiber optic connections between devices. The connection used for communication is called the media, which differ from one another by properties such as the maximum distance for each connection and maximum data transmission speed.
Node: Each device on the network is called a node.
Node Address: Each node will typically have a unique identifier called a node address.
Network: When multiple devices are connected together under a common device address space, we call this a network.
Topology: The physical structure of the network is called the topology.
