PROFINET IO
Within the context of Totally Integrated Automation (TIA), PROFINET IO is the systematic
development of the following systems:
● PROFIBUS DP, the established field bus,
● Industrial Ethernet, the communications bus for the cell level.
Experience gained from both systems was and is being integrated into PROFINET IO. As an
Ethernet-based automation standard defined by PROFIBUS International (PROFIBUS user
organization), PROFINET IO is a manufacturer-independent communication and engineering
model.
PROFINET IO defines every aspect of the data exchange between IO controllers (devices
with so-called "master functionality" and the IO devices (those with so-called "slave
functionality") as well as parameterization and diagnostic processes. An IO system is
configured by virtually the same method used for PROFIBUS.
A PROFINET IO system is assembled from the following devices:
● The IO controller controls automation tasks.
● An IO device is controlled and monitored by an IO controller. An IO device consists of
● IO supervisor is an engineering tool typically based on a PC that is used to parameterize
