General information about PROFINET IO

PROFINET IO is an open Industrial Ethernet standard for a wide range of production and
process automation applications. PROFINET IO is based on Industrial Ethernet and
observes TCP/IP and IT standards.
Deterministic signal processing in real time is important in industrial networks. PROFINET IO
satisfies these requirements.
The international standard IEC 61158 ensures open, multi-vendor systems:
PROFINET IO is tuned for high-speed, time-critical data transfers at field level.
PROFINET IO
Within the context of Totally Integrated Automation (TIA), PROFINET IO is the systematic
development of the following systems:
● PROFIBUS DP, the established fieldbus,
● Industrial Ethernet, the communications bus for the cell level.
Experience gained from both systems was integrated into PROFINET IO. 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 (devices with so-called "slave
functionality") as well as carrying out parameterization and diagnostics. A PROFINET IO
system is configured in virtually the same way as a PROFIBUS system.
A PROFINET IO system is assembled from the following devices:
● An IO controller controls automation tasks.
● An IO device is controlled and monitored by an IO controller. An IO device can consist of
several modules and submodules.
● An IO supervisor is an engineering tool, typically based on a PC, to configure e and
diagnose the individual IO devices (drive units).
