Introduction: What is IO-Link?

IO-Link is a leading standard in industrial automation that enables the simple and efficient integration of sensors and actuators into digital networks. It is a bidirectional communication interface that allows devices to send and receive data.

In contrast to conventional analogue interfaces, IO-Link offers digital data transmission, resulting in precise and reliable communication between devices. This transmission takes place via a uniform, standardised interface, regardless of the device type or manufacturer, which improves the interoperability and interchangeability of components.

In addition, IO-Link offers a range of functions to increase efficiency and flexibility in production. These include parameterisable device configuration, diagnostic functions for fast troubleshooting and the transfer of additional process and device data. This enables production engineers to comprehensively monitor and control their systems to optimise production processes.

Another advantage of IO-Link is its versatility and flexibility. IO-Link devices can be integrated into almost any fieldbus and control system infrastructure, allowing for easy integration and commissioning. In addition, IO-Link supports the processing of multiple measured values from different sensors simultaneously, resulting in comprehensive monitoring and control of production facilities.

Overall, IO-Link offers a powerful solution for optimising manufacturing processes through precise and reliable communication, flexibility in the integration and control of devices and a variety of functions such as condition monitoring and remote access.

Purely digital transmission

Maximum reliability

IO-Link offers production engineers the security of reliable data transmission at the highest level. By using a 24 V signal and purely digital transmission, communication between sensors, actuators and the controller is conversion- and loss-free. This means that the transmitted data remains precise and unaltered, resulting in a high level of accuracy and consistency in production.

Elimination of interference factors

Thanks to the digital and conversion-free transmission with IO-Link, potential interference factors are minimised. Signal losses or interference that can occur with analogue transmission are a thing of the past. This ensures constant and reliable communication between the devices, even in demanding production environments with strong electrical interference or EMC interference.

Simple integration and commissioning

The use of a 24 V signal and digital transmission make the integration and commissioning of IO-Link devices extremely simple and efficient. As no time-consuming calibration or adjustment is required , production engineers can quickly commission the devices and optimise their production facilities without delay.

Future-proofing and compatibility

IO-Link offers a future-proof solution for production engineers as they benefit from the advantages of digital communication that keeps pace with the latest technological developments. In addition, IO-Link is backwards compatible, which means that older devices can be integrated with new IO-Link systems without the need for expensive and time-consuming upgrades.

Seamless integration into existing infrastructures

Independent of fieldbus and control systems

Thanks to the flexibility of IO-Link masters, IO-Link devices can be easily integrated into almost any fieldbus and control system infrastructure. Whether Profibus, Profinet, EtherCAT or other fieldbus systems - IO-Link masters offer a universal interface that enables smooth communication between the various components. Production engineers can therefore expand existing systems or add new components without having to make major adjustments or investments in the infrastructure.

Flexibility and scalability

The ability to integrate IO-Link devices into different infrastructures offers production engineers a high degree of flexibility and scalability. They can expand their production facilities as required to meet new requirements or optimise processes without having to limit themselves to specific fieldbus protocols. This enables agile and cost-efficient adaptation to changing production requirements and helps to future-proof the systems.

Simplified configuration and commissioning

IO-Link masters also considerably simplify the configuration and commissioning of IO-Link devices. Thanks to their intuitive user interface and compatibility with common engineering tools, production engineers can commission the devices quickly and efficiently without the need for extensive programming knowledge. This reduces commissioning times and makes it easier to integrate new components into existing systems.

Compatibility with Industry 4.0 standards

The seamless integration of IO-Link devices into various fieldbus and control systems makes them an ideal solution for Industry 4.0 applications. IO-Link forms a solid basis for the implementation of intelligent manufacturing concepts, as it enables reliable and standardised communication between all levels of the production environment.

Reduced installation costs

Unshielded cables save costs

The insensitivity of IO-Link signal transmission to external interference offers a considerable advantage in terms of installation costs. By dispensing with shielded cables and the associated earthing, companies can achieve considerable savings in installation costs. As data transmission can be realised via standard industrial cables (three-core cables), there is no need for expensive special cables, which significantly reduces the overall cost of cabling .

Elimination of digital/analogue converters

The use of IO-Link technology also enables considerable savings to be made on equipment parts that are not immediately thought of. By becoming independent of costly analogue input cards (digital/analogue converters), companies can dispense with these components, resulting in direct cost savings. This enables companies to cost-effectively modernise or expand their production facilities without having to make additional investments in expensive input cards.

Condition monitoring and remote access

Monitoring in real time

In the field of condition monitoring, IO-Link offers an efficient solution for monitoring system statuses in real time. The ability to process several measured values from sensors simultaneously enables production engineers to gain a comprehensive insight into the condition of their systems. This enables early detection of deviations or potential failures, leading to a reduction in downtime and maintenance costs.

Remote access via the internet

IO-Link also enables remote access to sensor data and system control via the internet. Production engineers can therefore access the systems from any location and make settings or carry out diagnostics without having to be on site. This improves responsiveness and efficiency in the maintenance and optimisation of production systems and contributes to increasing overall productivity.
The combination of condition monitoring, processing of multiple measured values and remote access via IO-Link offers companies a powerful solution for optimising their manufacturing processes and maximising system availability.
