1.6 PROFINET
1.6.1 Overview of PROFINET
PROFINET is a fieldbus network that uses industrial Ethernet.
PROFINET was developed as an open communication standard to connect various field
devices (sensor, actuator, Robot Controller, etc.). Because of the open communication
standard, PROFIBUS DP can easily construct multi-vendor system with various devices
developed around the world.

1.6.2 Features of PROFINET
Everything on one cable
With its integrated, Ethernet-based communication, PROFINET satisfies a wide range of
requirements, from extremely fast I/O data transmission to parameter monitoring and
configurations of equipment.
Flexible network topology
PROFINET is 100% Ethernet compatible according to IEEE standards and adapts to the
environment of existing plant due to its flexible line, ring, and star structures.
Standardization
PROFINET is defined by international standards “IEC 61158” and “IEC 61784”.
Concept of PROFINET has been developed based on standard Ethernet of IEEE802
through a joint effort with its users. Functionality has been added to cover the area that
standard Ethernet cannot satisfy.
