IO-Link with Bihl+Wiedemann: Easy, Flexible & Cost-efficient

IO-Link devices are nowadays common in machines and systems. This is because IO-Link allows sensors and actuators to be connected to the control level via a cost-effective point-to-point connection. Find out more about IO-Link and the associated advantages here.   

 

This page mainly deals with the following question: What is the best way to integrate IO-Link? Bihl+Wiedemann offers you a sophisticated concept for this: IO-Link can be embedded perfectly in ASi-5and our user-friendly PC software – from the device to the PLC or cloud. Our solution provides more benefits than just freedom of topology, reduced wiring complexity without switches, and a smart power supply concept. Other advantages include reduced IP management complexity and low-cost IO-Link masters, which we provide with 1, 2, 4 and 8 ports. Numerous technical features also enable you to commission IO-Link devices with maximum convenience. For us, one thing is certain: There is no smarter and more economical way to integrate IO-Link.

Advantages at a glance

Einfachste
Inbetriebnahme

Über unser komfortables Konfigurationstool lassen sich IO-Link Master leicht einbinden. Sie können z. B. die IODD einfach aufrufen und werden bei der Parametrierung von IO-Link Devices grafisch unterstützt. Die Live-Parametrierung der Devices ermöglicht eine direkte Kontrolle der vorgenommenen Einstellungen.

Automatische Parametrierung beim Gerätetausch

Bei der Mehrfachverwendung eines Setups können die Parameter der angeschlossenen IO-Link Devices dank unserer PC-Software einfach von Master zu Master kopiert werden. Dies gilt sowohl innerhalb von Projekten als auch projektübergreifend. Die Kopierfunktion spart besonders beim Einsatz vieler IO-Link Devices sehr viel Zeit und reduziert Parametrierfehler.

Integrierter
OPC UA Server

Unsere ASi-5/ASi-3 Gateways besitzen alle einen integrierten OPC UA Server. Dieser ermöglicht es Ihnen, die Prozess-, Parameter- und Diagnosedaten der IO-Link Devices einfach und kostengünstig in die Cloud oder HMI zu übermitteln – eine Voraussetzung für moderne Anlagen in Zeiten von Industrie 4.0.

Geringer
IP Verwaltungsaufwand

An unser Gateway lassen sich über 2 ASi Kreise weit über 100 ASi Teilnehmer mit je bis zu 8 IO-Link Devices anschließen. Alle Signale werden kompakt und gebündelt an die SPS übermittelt. 

Dadurch müssen Sie nur 1 IP-Adresse vergeben und verwalten.

Smart
Wiring Concept

The amount of effort required for wiring is reduced because all nodes – IO-Link devices, standard sensors and safety modules – are connected to an unshielded 2-core cable using piercing technology. Besides, the maximum IO-Link cable length of 20 meters plays a secondary role in our case because you can distribute the IO-Link masters anywhere on the AS-Interface cable with up to 200 meters in length.

Smart
Energy Distribution

In round cable solutions, the respective connector indirectly determines the "limit" for individual IO-Link masters and for the total current of all IO-Link masters connected in series. With ASi, no loop-through from module to module is needed . The AUX supply is done over reverse polarity protected profile cables, so each IO-Link master draws its energy individually – at 20 A per AUX cable.

Full
Flexibility

While common IO-Link masters are only available from 4 ports or more, ASi also offers the possibility to efficiently integrate 1- or 2-port IO-Link masters. This means that even distributed individual IO-Link devices can be perfectly integrated. You also enjoy great freedom in the choice of topology

and can implement a star, ring, line and network structure, for example. You also gain maximum flexibility through the fieldbus independence of our IO-Link masters.

Reduced
Overall Costs

Our IO-Link masters with 4 ports are, for instance, about 50 % cheaper than comparable modules from other manufacturers. This means that the costs for our gateway are recovered, for example, from just 3 IO-Link masters with 4 ports each. You also reduce your installation workload and benefit from the elimination of switches and pre-assembled cables. Click here to view our main cost comparison.

 

IO-Link with Bihl+Wiedemann

  • The IO-Link master is integrated as an ASi node into the ASi network

  • IO-Link devices can be integrated into the ASi network along with standard sensors, standard actuators and safety components

  • All process data (up to 32 bytes per port) of the IO-Link devices is available via the cyclic ASi communication.

  • All IO-Link parameters can be conveniently adjusted through the B+W Software Suite or acyclically via the control system

  • Diagnostic information from IO-Link available via ASi

  • Our IO-Link masters can be optimally combined with IO-Link devices from any manufacturer

  • If an IO-Link device needs to be replaced, its parameters are stored in the IO-Link master and are transferred automatically to the new one.

 

IO-Link products

All IO-Link masters offer up to 32 bytes of cyclic process data per port and up to 4 x 16 bits of usable data are available in 1.27 ms each. The Bihl+Wiedemann software suites always enable convenient parameterization.

    IO-Link Safety Solutions from Bihl+Wiedemann

    IO-Link Safety is an extension of IO-Link. There is an additional safety communication layer on the master and device side. These become the "Fail-Safe (FS) master" and "Fail-Safe (FS) device". Bihl+Wiedemann is in the process of developing its own "FS master". IO-Link is already a perfect match for the safety components of Bihl+Wiedemann.

    FAQ about IO-Link

    The open IO-Link interface requires only a simple standard industrial cable. Intelligent sensors and actuators can be connected in a cost-efficient manner on an unshielded three- or five-wire cable. For point-to-point communication, each IO-Link device needs an IO-Link master.

    The IO-Link master handles the communication to the intelligent sensors and actuators. It enables parameterization, diagnostics and access to the cyclic data by means of a connection to the control system.

    Reduced machine-related costs

    A cost-efficient standard cable establishes a connection up to 20 meters long between the IO-Link master and IO-Link device.

     

    High machine availability

    Downtimes are reduced because when a defective IO-Link device is replaced, its parameters are automatically transferred to the new sensor by the IO-Link master or control system.

     

    Efficient operation

    IO-Link devices can be positioned in the machine directly at the work site. These do not have to be accessible for parameterization.

     

    Demand-oriented maintenance

    Continuous diagnostic data of the entire process lengthen maintenance intervals, since systems and machines need to be maintained much less frequently due to the automatic readjustment via IO-Link

     

    More information about the advantages of IO-Link

    It is possible to extend existing bus systems. As a prerequisite, the system mapping of IO-Link for the respective bus system must be already implemented. It is particularly easy to use IO-Link in conjunction with the ASi intelligent wiring system. Thanks to piercing technology, corresponding IO-Link masters can be easily retrofitted where they are needed.
