Communication between devices

Communication
The data exchange between devices is referred to as communication.
The devices can be interconnected directly or via a network.
The interconnected devices in communication are referred to as communication partners.
Data transferred between the communication partners may serve different purposes:
● Display processes
● Operate processes
● Output alarms
● Archive process values and alarms
● Document process values and alarms
● Administer process parameters and machine parameters
Basic information for all communication
The basis for all types of communication is a network configuration. In a network
configuration, you specify the connection that exists between the configured devices.
With the network configuration, you also ensure the necessary prerequisites for
communication, in other words:
● Every device in a network is assigned a unique address.
● The devices carry out communication with consistent transmission characteristics.
