IO-Link solutions

Smart manufacturing solutions

Hot on the heels of Lean Manufacturing, the focus has once again changed.

With the goal to improve manufacturing performance, using more automated operations and the use of data analytics, smart manufacturing is the order of the day. This technology-driven approach, using machinery connected to the internet to monitor the production process, has seen the development of smart machine components.

SMC's IO-Link products can help you improve your productivity and reduce your costs, granting dynamic production processes and leading to the Smart Flexibility the industry is seeking. Plus, they will let you bet on the continuous improvement of your company’s industrial maintenance strategy.

For more information on our smart machine solutions check out our latest products on our website today.


What benefits will you get from IO-Link devices?

  • Time and money savings thanks to reduced wiring operations
  • Intelligence and communication to the standard sensors without additional costs
  • Reduced spare parts thanks to the standardisation of input/output modules.

IO-Link to move easily to smart sensor

By Mile Milovanovic, Senior Engineer, SMC German Technical Centr

When it was launched in 2009, IO-Link was unlike anything the industry had ever seen before. IO-Link is not a fieldbus, but an ally to fieldbus. IO-Link connects automation IO-devices in a way that other solutions haven’t been able to offer.

What is IO-Link 

IO-Link (IEC61131-9) is an open standard technology that allows the bidirectional data exchange from sensors and devices that support IO-Link and are connected to a master.Thanks to an IO-Link master, data is transmitted over various networks, fieldbuses, or backplane buses, making the data accessible for immediate action or long-term analysis via an industrial information system (PLC, HMI, etc.).

The advantages of IO-Link with SMC

Increased data availability

Increased data availability

There are three primary data types made available, which are categorised into cyclic data (data automatically transmitted on a regular basis) or acyclic data (data transmitted as needed or upon request).

  • Process Data. What the device reads.
  • Service Data. Information about the device itself.
  • Event Data. Notifications (diagnostic).
Increased data availability

Product diagnostic

Product diagnostic

No need to wait for a process failure to replace a sensor.

With the implementation of the IO-Link technology, the devices are always being monitored to know the state of their health with Event Data.

Depending on the device, you can track if they are suffering excessive temperature, pressure, if they are out of range, internal default, etc.

Standard wiring

Standard wiring

The entire measured value transmission is digital, thus, all device parameters are stored in the IO-Link unit. The data transfer is based on a 24 V-signal and the shielded wires are not required.

Standard wiring

Remote access

Remote access

Customised solutions force a continuous change in parameters. The overall setting control from the control system (PC) minimises time, increasing machine availability.

Remote access

Easy device replacement

Easy device replacement

Plug & play replacement simplifies the connection: a common connector for communication and power. Parameters are saved in the master, enabling automatic setting once the device is connected.
