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

What is IO-Link?

IO-Link is a fieldbus-independent interface that ensures seamless communication down to the "last meter" at the field level. With IO-Link, sensors and actuators can be connected to the control system level via a cost-efficient, point-to-point connection on a standard, unshielded three-core cable. Being an open interface, IO-Link can be integrated into all common fieldbus and automation systems.

 

The international IO-Link standard (IEC 61131-9) enables central fault diagnosis and localization down to the actuator/sensor level. Further information, such as parameters or diagnostic messages, are exchanged in addition to process values. IO-Link devices can even be adapted to the respective production requirements via the control system during operation.

Advantages of IO-Link

IO-Link is an internationally standardized, manufacturer-independent interface. The open standard (IEC 61131-9) is compatible with all common fieldbuses when implemented with a gateway.

IO-Link with Bihl+Wiedemann

Multiple cost-savings

Using IO-Link Devices with solutions from Bihl+Wiedemann saves costs in many ways:

 

  • You only pay for as many IO-Link ports as you really need – because in addition to the 4-port IO-Link master we also offer you IO-Link masters with 1 and 2 ports
  • The amount of effort required for cabling is reduced because all participants – IO-Link devices, standard sensors and safety modules – are connected to an unshielded 2-wire cable using piercing technology
  • You can integrate significantly more IO-Link masters per Ethernet node and benefit from freely selectable topology as well as the elimination of switches and pre-assembled cables
  • Thanks to the integrated OPC UA server in our gateway, you can transfer process and diagnostic data of IO-Link devices to the Cloud in an easy and cost-efficient manner. This means you are well prepared for industry 4.0 applications, such as predictive maintenance.

Simply user-friendly

Our goal is to offer you a top user-friendly solution for IO-Link:

 

  • You can easily integrate IO-Link devices where you need them. In our wiring system, the maximum IO-Link cable length of 20 meters plays a subordinate role because you can distribute the IO-Link masters anywhere on the AS-Interface using cables up to 200 meters in length
  • You can combine our IO-Link masters optimally with IO-Link devices from various manufacturers
  • You benefit from easy integration of the IO-Link master via our configuration tool, e.g. by simply loading the IODD and by supporting sensor parameterization with graphics

What makes IO-Link integration with Bihl+Wiedemann unique?

1-port IO-Link master; no "unused" IO-Link ports

IO-Link devices are widely distributed in many systems. But the maximum cable length between an IO-Link master and IO-Link device is 20 meters. This is no problem with Bihl+Wiedemann. With our compact IO-Link masters with 1 or 2 ports, you can also easily connect individual IO-Link devices at any location – distributed over the AS-Interface cable length of up to 200 meters. The "smallest" modules of other manufacturers usually have at least 4 IO-Link ports. In practice, this often leads to "unused" IO-Link ports. Because if there are only 2 IO-Link devices within a radius of 20 meters, you would still have to pay for the 4 IO-Link ports of the "small" IO-Link master.

Gateway as an additional intermediate level

With Bihl+Wiedemann, the IO-Link masters are not directly connected to the PLC. Between our IO-Link masters and the PLC there is our gateway at an intermediate level. This combines all signals of the IO-Link devices and transmits them to the PLC. Our IO-Link modules are significantly cheaper than comparable Industrial Ethernet devices. Our gateways, which are necessary for an installation, pay for themselves using only 3 IO-Link masters with 4 ports each. Another advantage of the gateway is the integrated OPC UA interface. It enables the process and diagnostic data of the IO-Link devices to be transferred to the Cloud in an easy and cost-efficient manner – a prerequisite for predictive maintenance.

The big cost comparison – IO-Link with Bihl+Wiedemann

In many application scenarios, IO-Link solutions from Bihl+Wiedemann are much more cost-efficient than similar solutions from other providers. An application with Bihl+Wiedemann is already cheaper than comparable PROFINET variants from three 4-port IO-Link masters. Another factor is the finer granularity. Our 1-port IO-Link master allows you to integrate an IO-Link device exactly where you need it. Thanks to cable-piercing technology, it is extremely easy to install our IO-Link master. You can substantially reduce the time required for assembly.

The larger your application, the more you save

The more devices you need for your control system, the greater your cost advantage when you choose an IO-Link solution from Bihl+Wiedemann. For example, in a medium-sized application with 50 IO-Link devices, you can save up to 40%* against a comparable PROFINET, EtherNet/IP or EtherCAT version.

IO-Link cost comparison in detail

The price comparison is based on the following assumptions:

  • Only 4-port IO-Link masters with 4 ports each are used or compared.
  • IO-Link devices (sensors or actuators) can only be connected using an IO-Link master. A maximum of 4 IO-Link devices can therefore be connected to a 4-port IO-Link master. Therefore, three 4-port IO-Link masters with a total of 12 ports are required to connect 10 IO-Link devices.
  • The price comparison based on list prices does not take discounts into account. These must be included for exact cost comparison.
  • Further cost savings through to the simple AS-Interface wiring system are not included in the price comparison.

  • Process data from the IO-Link sensors, such as exceeding a switching threshold, are made available via the cyclical ASi communication
  • Diagnostics information available over ASi from IO-Link

Integrating the IO-Link Master Using our Configuration Tool

  • Simply access the IODD (IO Device Description) using the IO-Link configurator in ASIMON360 (BW2916, BW3065, BW2902)
  • Graphic support for configuring the connected sensors

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.

FAQs 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

No. IO-Link is a point-to-point connection between an IO-Link master and an IO-Link device (sensor or actuator). The connection's cable length can be up to 20 meters.

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.
