PROFINET IO
PROTOCOL
PROFINET is the Ethernet-based automation standard of PROFIBUS International for the imple-
mentation of an integrated and consistent automation solution based on Industrial Ethernet. PRO-
FINET supports the integration of simple distributed field devices and time-critical applications in
(switched) Ethernet communication, as well as the integration of component-based distributed au-
tomation systems for vertical and horizontal integration of networks.
The VACON
®
100 AC drive implements PROFINET IO version 2.3 with conformance class B and the
netload class I, making it suitable for use in larger automation systems.
5.1
PROFIdrive 4.1 profile
To provide interoperability between devices from different manufacturers, a "standard" must be
defined so that:
•
The devices behave in the same way.
•
They produce and/or consume the same basic set of I/O data.
•
They contain the same basic set of configurable attributes.
The formal definition of this information is known as a device profile.
