Basics of communication with Industrial Ethernet
1.2 Industrial Ethernet
Technical requirements
Communication networks are a central part of modern automation solutions. Industrial
networks must fulfil special requirements, for example:
● Coupling of automation systems, PCs as well as simple sensors, actuators and
computers
● Robust against electromagnetic interference, mechanical stress and pollution
● Integration of existing systems and expandability
● IT communication to integrate modern information technology
● Simple cabling technology
● Flexible adaptation to the production requirements
● Availability of information at any location
● Correct transfer of information and at the right time
● Integrated diagnostics
● Deterministic - no undefined statuses
● Fast data exchange between parts of the plant
● Integrated security functions preventing unauthorized access
● Sale-safe standard communication over the same connection
Industrial networks are part of the LANs (Local Area Networks) and enable the
communication in a regionally limited area.
