IO-Link Safety

With IO-Link Safety, you can safely integrate sensors up to field level – quickly, conveniently and standardised worldwide in accordance with IEC 61139-2. Point-to-point communication enables maximum safety up to PL e (SIL 3) and is independent of the fieldbus used.

Benefits to you:

• Safe communication from controller to sensor
• Optimised process diagnostics thanks to advanced data analysis
• Complete system with Master and sensors from Pilz
• Integration support from our experts

Benefit from our expertise as partner and developer of IO-Link Safety – we can help you integrate it into your application!

Discover how IO-Link Safety makes your automation safer, more efficient and sustainable. In the webinar, our experts provide concise insights into:

• IO-Link & IO-Link Safety – What’s behind them?
• The benefits for your application
• Technical principles
• The Pilz IO-Link Safety System
• Practical examples and industrial applications

(The webinar is only available in English.)

Increase your productivity

IO-Link Safety devices identify themselves automatically and adopt parameters directly. This makes them easier to exchange, reduces downtimes and cuts the number of types – meaning less storage costs and greater efficiency.

Save time 

Simple point-to-point connection with standard cables and connectors makes installation easier. The devices are configured conveniently via the PLC parameter settings or using the Pilz configuration tool - for rapid commissioning.

Optimise your processes

IO-Link Safety delivers diagnostic data directly to the controller - for targeted maintenance and optimised processes. That way you increase the transparency of your machine states and can use the data for process optimisations.

Are you using a large number of safety sensors in your plants? Then IO-Link Safety is the right solution for you. This extension of the IO-Link technology enables safe, seamless communication from the controller to the safety-related sensors. Simple field integration with rapid wiring and data diagnostic options offer huge potential to implement your automation both flexibly and productively.

Packaging plant with access guarding 

• Requirement:  

Save time and space when integrating the safety sensors.  

• Solution: 

Decentralised IO-Link Safety Master PDP 67 IOLS for the integration of safety light curtains PSENopt II Advanced IOLS and safety gate guarding. The E-STOP and the IO-Link signal lights are also connected to the IOLS Master. 

• Benefits: 

Space-saving integration via decentralised Master in the field, plus simplified wiring Considerable time saving during installation. 

Material handling with integrated robotics

• Requirement:  

Safeguarding of access points and safety gates, plus a minimising of machine downtimes.

• Solution:  

Safety light curtains with muting function and the control unit PITgatebox IOLS are integrated via the Pilz IO-Link Safety Master. This serves as the “IO-Link Safety hub” for the safety locking device PSENmlock. 

• Benefits:  

Simple, time-saving integration of the safety sensors, plus intelligent data diagnostics for predictive maintenance.

To integrate IO-Link Safety you need a Master, field devices such as safety sensors and the right cable and configuration tool. Pilz offers the complete one-stop system – safe and reliable.

IO-Link Safety Master

As the interface to the safety controller, the IO-Link Safety Master enables point-to-point communication up to field level. With the Pilz Master PDP 67 IOLS, you can also connect IO-Link sensors and classic safety sensors alongside the IO-Link Safety devices.

IO-Link Safety devices 

IO-Link Safety devices communicate directly with the IO-Link Safety Master and provide important status information. With the safety light curtains PSENopt II Advanced IOLS, Pilz offers the first IO-Link Safety device for access guarding. The control unit PITgatebox IOLS can be used in conjunction with the safety locking device PSENmlock for safety gate guarding.

Cable and configuration tool

IO-Link Safety uses 3-core, unshielded standard cable. Up to 32 Bytes of data are transmitted in two directions with IO-Link Safety, at up to 230.4 kbit/s. You will find this cable in the right lengths for your application in the Pilz portfolio. With the Pilz configuration tool you can configure and set parameters for the IO-Link Safety Master and devices.
