PROFINET
PROFINET is the open, cross-vendor Industrial Ethernet
standard (IEC 61158/61784) for automation.
Based on Industrial Ethernet, PROFINET enables direct
communication between field devices (IO devices) and
controllers (IO controllers), up to and including the solution of
isochronous drive controls for Motion Control applications.
As PROFINET is based on Standard Ethernet according to
IEEE 802.3, any devices from the field level to the control level
can be connected.
In this way, PROFINET enables system-wide communication,
supports plant-wide engineering and applies IT standards, such
as Web server or FTP, right down to field level.
Tried and tested fieldbus systems, such as PROFIBUS or
AS-Interface, can be easily integrated without any modification
to the existing devices.
PROFIBUS
PROFIBUS is the international standard (IEC 61158/61784) for
the field level. It is the only fieldbus to allow communication both
in manufacturing applications and in process-oriented
applications.
PROFIBUS is used to connect field devices such as distributed
I/O devices or drives to automation systems such as
SIMATIC S7, SIMOTION, SINUMERIK or PCs.
PROFIBUS is standardized in accordance with IEC 61158 and is
a powerful, open and rugged fieldbus system with short
response times. PROFIBUS is available in different forms for
various applications.
AS-Interface
AS-Interface is the international standard (IEC 62026/
EN 50295) which, as an alternative to the cable harness, links
particularly economical sensors and actuators in the field level
by means of a simple two-wire cable. This two-wire cable is also
used to supply the individual stations with power. Therefore the
AS-Interface is the ideal partner for the fieldbus PROFIBUS DP.
IO-Link
The IO-Link communication standard creates an intelligent
connection between sensors and switching devices at the
control level. IO-Link simplifies the integration of all of the
components in the control cabinet and at the field level for
maximum uniformity and seamless communication in the last
meters to the process.
IO-Link solutions from Siemens ensure highest precision and
profitability in any production. IO-Link is completely integrated
into Totally Integrated Automation (TIA) and offers many
benefits.
