IO-Link Communication Standard 

IO-Link

Seamless communication right through to the final steps of the process

Consistent cost reduction, high plant availability, and transparency - the requirements of point-to-point industrial communications are constantly increasing. At the same time, the actuators and sensors employed are becoming increasingly intelligent. This is where the open IO-Link communication standard comes in, enabling you to complete the final steps in the process - with data transparency from the sensor/actuator level all the way to the automation level. Not only do you benefit from a simple, consistent and inexpensive point-to-point connection, through which sensors and actuators can be linked to the control level, but also from systematic diagnostic concepts and efficient handling of parameter data on all levels of the automation system. IO-Link is the ideal basis for creating efficient transparency - not only in the control cabinet but also at field level.

IO-Link Master

IO-Link Master

IO-Link Master - integrating sensors and actuators in PROFIBUS and PROFINET

To link IO-Link devices with your automation system, Siemens offers you a choice of IO-Link master devices for non-central peripherals, the SIMATIC ET 200 and the SIMATIC S7-1200 controller. These IO-Link master modules integrate fast and simple IO-Link communication with sensors and actuators in the established PROFIBUS and PROFINET field bus systems, and thereby in Totally Integrated Automation.

IO-Link masters from Siemens can be used to link IO-Link-certified sensors and actuators in all areas of production automation. Project planning of IO-Link channels can be performed easily, quickly and conveniently using the S7-PCT port configurator tool, which is integrated in STEP7 Engineering and is also available as a separate tool.

Industrial Switchgear IO-Link

Industrial Switchgear

Industrial switchgear - compact starters, function modules and contactors for IO-Link

Siemens industrial switchgear includes everything you need to integrate actuators into your automation system via IO-Link - easily, efficiently and reliably.

 

Whether compact starters, function modules for attaching to contactors, power contactors for motor switching, monitoring and temperature-monitoring relays, electronic overload relays or an electronics module - SIRIUS supplies you with all products with an IO-Link interface.

Commanding and Signalling Devices

Commanding and signalling devices - key switches and electronic modules for IO-Link

Even SIRIUS ACT commanding and signalling devices can be connected to IO-Link. This includes the electronic SIRIUS ACT ID key switch, incorporating the latest RFID technology. This ensures that only authorised persons are able to operate the plants and machinery. It is also possible to quickly and safely connect SIRIUS ACT push buttons and light signalling devices to IO-Link, using special electronics modules for IO-Link.

RFID-Reader

RFID readers - compact system in high frequency range for IO-Link

The SIMATIC RF 200 IO-Link RFID system was conceived for identification operations, such as reading ID numbers. The system comprises space-saving HR readers, which are especially useful in intralogistics and small assembly lines, where they enable very simple identification tasks, e.g. reading an ID number or any user data (‘read only’). It is especially cheap and simple to integrate the data read by the reader in the automation level with the aid of a standard interface for IO-Link.

IO Modules

IO Modules - for saving space in the control cabinet

The compatibility of IO-Link also enables the connection of standard sensors and actuators. This is particularly cost-effective with IO-Link input modules, as they allow the connection of several sensors to the controller through the same connection line. This results in considerably smaller wiring requirements, and thus more space in the control cabinet. In particular, IO-Link input modules are now found in areas where passive sensor boxes used to be used for connecting binary sensors. Passive distributors with their complex and error-prone wiring are now a thing of the past.

 

Software

Software - for fast and efficient engineering and visualisation

IO-Link software tools and functional modules ensure the standardised and efficient engineering and visualisation of diagnostic information. For instance, the PC-based S7 port configuration tool simplifies the parametrisation of Siemens IO-Link master modules and IO-Link devices from any manufacturer. In addition, Siemens supplies IODD device description files as well as functional modules and UDTs for all IO-Link devices in the Siemens portfolio that harmonise and simplify communication between IO-Link devices.

The future with IO-Link

IO-Link from Siemens - fully integrated in TIA

The IO-Link solution from Siemens ensures communication between sensors and actuators, and completes the final steps in the process with consistent data transparency. It is thanks to its seamless integration in the Totally Integrated Automation (TIA) concept that this communication standard is really able to develop its full potential - both in the control cabinet and at field level.

Simple integration of sensors and actuators in the data flow

To be equipped for future demands, data transparency and communication must reach down deeper than merely to the control level. So what is the optimum way of integrating and making the most of the growing intelligence of sensors and actuators in the automation system? The answer is supplied by Siemens, in the form of the open communication standard, IO-Link.

 

IO-Link solutions from Siemens allow you to enjoy maximum precision and cost-effectiveness in any production facility. Enabling data access to the lowest field level not only increases plant availability but also reduces engineering expenditure. The IO-Link communication standard is fully integrated in TIA and offers you many advantages.

Features & benefits

More efficiency on all levels

Automation with an open Standard
IO-Link is used to link switchgears and sensors to the control level via an inexpensive point-to-point connection. As an open interface, IO-Link can be integrated in all common field bus and automation systems. The IO-Link Consortium supports the concept in all areas of control engineering and sensor and actuator technology.

 

Its consistent interoperability results in a high level of investment protection, even with existing machine concepts for allowing the continued use of sensors that have no IO-Link interface. In addition, interoperability gives you a free product choice and you can benefit from guaranteed further development.
