IO-Link is an open communication standard developed by
the IO-Link research group of the PROFIBUS & PROFINET
International organization in response to the need for a simple,
low-cost way to allow actuator and sensor communication in
a concentrated area, such as for a control panel or individual
machine. IO-Link is a point-to-point system, not a fieldbus. It
uses a three-wire cable, 24 VDC power supply, and an IO-Link
master.
Safety Integrated
Safety has long been an important consideration in factory
operation. As Werner von Siemens, the founder of Siemens,
stated in 1880, “the prevention of accidents must not be
understood as a regulation required by law, but at a precept of
human responsibility and economic reason.”
Unfortunately, regulations are necessary to both clarify and
promote appropriate standards. In addition, these regulations
need to be modified periodically to adapt requirements to
changes in technology.
In recent years, safety has taken on an even greater importance
both as a result of changing regulations and standards and
the emergence of new technologies. As a result, Siemens
developed the Safety Integrated system which includes
products which offer comprehensive and consistent safety
solutions for production and process industries. Because Safety
Integrated has been developed consistent with Siemens Totally
Integrated Automation (TIA), both standard and safety-related
components are combined in one uniform system. This results in
considerable cost savings for our customers.
Included in the extensive array of Safety Integrated products are
fail-safe SIMATIC PLC Central Processing Units (CPUs), fail-safe
SIMATIC ET 200 Input/Output (I/O) devices and systems, SIRIUS
Safety Integrated industrial controls, and fail-safe drives and
motion control systems.
Because Safety Integrated uses proven PROFINET, PROFIBUS, and
AS-Interface networks for fail-safe communication, engineering
and installation costs are significantly reduced. Where needed,
PROFIsafe and ASIsafe can be used. PROFIsafe is an open
solution for safety-oriented communication that uses PROFINET
and PROFIBUS services. ASIsafe is the safety version of the AS-
Interface system.
