IO-Link – more than just another interface
IO-Link is a smart concept for the uniform connection of
switching devices and sensors to the control level by means of
a low-cost point-to-point connections.
The IO-Link communication standard below fieldbus level
enables central error diagnostics and localization down to
actuator/sensor level, and facilitates both start up and mainte-
nance by allowing parameter data to be dynamically changed
directly from the application.
The increasing intelligence of field devices and their integration
into automation as a whole now allows data to be accessed right
down to the lowest field level. The result was: greater plant
availability and less engineering work.
As an open interface, IO-Link can be integrated into all standard
fieldbus and automation systems.
The advantages of IO-Link at a glance
• Engineering
reduced engineering times
- Standardized, open system for greater flexibility
(non-Siemens IO-Link devices can be integrated in
engineering)
- Uniform, transparent configuring and programming through
integrated engineering (SIMATIC STEP 7)
- Unassigned function blocks for SIMATIC for easy
parameterization and diagnostics, and for reading out
measured values
- Efficient engineering thanks to pre-integration of Siemens
devices into SIMATIC HMI
- Low error rate in CAD circuit diagram design as a result of
reduced control current wiring
•
Installation and commissioning
reduced start up times
- Faster assembly with minimized error rate as a result of
reduced control current wiring
- Less space required in the control cabinet
-
Low-cost circuitry where there are several feeders by making
unlimited use of existing Siemens components
•
Operation and maintenance
greater plant availability
- High transparency in the system right down to field level
- Reduction in downtimes and maintenance times thanks to
system-wide diagnostics and faster fault correction
- Support of predictive maintenance
- High transparency through integration into energy manage-
ment systems, reading out of current values and diagnostic
signals
- Shorter changeover times, even for field devices, by means
of parameter and recipe management
Transparency in the process through IO-Link
High system availability and data transparency are market
requirements that must also be met by the connecting of innova-
tive control technology to a control system. A systematic diag-
nostics concept and efficient handling of parameter data are
required for this purpose in automation.
With the aid of the IO-Link communication standard, a commu-
nication link is established between switchgear and controller,
and this allows data to be exchanged efficiently. Based on a
standard cable, it is therefore possible to integrate parameter,
process and diagnostic data and measured values into the plant
automation with ease. For example, the available diagnostic
data allow potential errors to be detected quickly, thus avoiding
lengthy plant down times.
As a consequence of their basic function, such as overload
protection (SIRIUS 3RB24), many controls have measured
values. The availability of these via IO-Link now allows conclu-
sions to be drawn at an early stage concerning wear and tear in
the application.
At the same time the option of parameterizing via IO-Link
supports the device not just when parameters concerning
operating time are changed, but also when the device is
replaced. In the case of a spare part, for example, the para-
meters can be quickly transmitted to a new device via the
communication system.
