LAPP takes automation to the next level: New I/O-link devices for decentralized use

LAPP is expanding its industrial communication product range with I/O-Link devices that enable bidirectional data transmission. These active components are ideally suited for decentralized use outside the control cabinet.

Decentralized Use

IO-Link is a standardized communication system developed specifically for integrating sensors and actuators into automation systems. It enables communication between an IO-Link device (e.g., a sensor) and an IO-Link master. This allows decentralized collection and control of process data by connecting sensors and actuators to the control system via a fieldbus interface. IO-Link enables bidirectional transmission of process data and parameters for configuring sensors and actuators.

Ideal for Conveyor Systems

I/O-Link devices significantly reduce the number of connection cables required, saving both time and costs. Typical applications include conveyor systems used in intralogistics. Multiple sensors and actuators are needed to ensure that long conveyor lines operate as expected, transporting goods quickly and safely. Without I/O-Link devices, field‑level cabling would be more complex, more expensive, and more prone to errors.

Multiple Protocol Options

“Together with our M12 connection cables, sensor‑actuator combinations, and Ethernet ready‑made cables, the new I/O‑Link devices form a complete end‑to‑end solution for networked systems,” says Jürgen Greger, Product Manager for Industrial Communication at LAPP. I/O‑Link devices enable bidirectional communication all the way down to the field level.

The new products include the IO‑Link masters UNITRONIC® ACCESS MP08 IOL and UNITRONIC® ACCESS SP08 IOL, as well as the IO‑Link hub UNITRONIC® ACCESS HUB08 IOL, all of which use standardized IO‑Link technology. Digital sensors and actuators can be easily integrated into an IO‑Link network. IO‑Link also enables extended diagnostics for sensors and actuators, and simplifies the commissioning and replacement of IO‑Link devices thanks to its plug‑and‑play functionality.

A special feature is the wide range of functions and protocols supported. The single‑protocol I/O‑Link master, the multi‑protocol I/O‑Link master, and the I/O‑Link hub all support IO‑Link technology. Single‑ and multi‑protocol versions are available for industrial Ethernet protocols such as PROFINET, Ethernet/IP, EtherCAT, Modbus TCP, and CC‑Link IE, depending on the model. The desired protocol is selected using a rotary code switch.

Made in Germany

The I/O‑Link master and the digital module are configured via a web browser. The I/O‑Link hub is set up using the I/O‑Link master. Both shielded and unshielded cables can be used for I/O‑Link communication, with a maximum cable length of 20 meters. Jürgen Greger summarizes: “Compared to Ethernet communication, I/O‑Link is more cost‑effective and easier to integrate. In addition, our I/O‑Link devices are manufactured in Germany, ensuring their high quality.”
