01 / The technology
Cut the cord
Keep the precision.
IO-Link Wireless combines the flexibility of wireless communication with the demands of industrial automation: deterministic, highly reliable and standardized.
Exceptional reliability
Frequency hopping, channel management and retransmissions support a residual error probability in the range of 10⁻⁹.
For demanding wireless environmentsFreedom to rethink machine design
Eliminate cable carriers and wear-prone data cables on moving components. Gain design freedom for robotics, tools and modular machines.

Wireless technology is complex.
Your integration does not have to be.
That is exactly why we developed the INNIRION Device SoM.
02 / The system-on-module
All the Wireless Technology.
None of the Complexity.
Our IO-Link Wireless Device SoM handles all wireless communication, from pairing and radio timing to retransmissions and connection monitoring. Your microcontroller simply speaks SPI.
Integrate powerful industrial communication without developing your own wireless stack. Focus on the features that make your product unique.
COMPACT SOMMCU-independent via SPIRegister-based APIComplete IOLW protocol inside the SoM
Any Microcontroller.
From 8-bit to 32-bit: an SPI master interface and suitable electrical connections allow the SoM to work with a wide range of microcontrollers.
No Wireless Stack.
The SoM handles radio scheduling, frames, retransmissions, pairing and monitoring. No custom implementation of time-critical wireless functions is required.
Process Data. ISDU. Events.
Access cyclic process data, parameters and diagnostic events through a single SPI register interface.
Your Product. Your Identity.
Your host firmware defines the device identity, process data lengths and application-specific content.
Reconnect with Ease.
Pairing parameters are stored in non-volatile memory and can be reused for subsequent connections to the paired master.
Tiny Footprint.
Just 12.9 × 15.0 mm, with flexible antenna connectivity. Designed for direct integration into compact sensors and actuators.
03 / Simple integration
Your MCU speaks SPI.
Our SoM speaks IO-Link Wireless.
The SoM separates your application firmware from wireless complexity. All your microcontroller needs is a simple host interface.

Any questions?
Good to Know.
The essentials of integration at a glance.
Does the SoM work with any microcontroller?
It works with any suitable microcontroller platform that can act as an SPI master and meets the required electrical conditions. The interface is not tied to a particular CPU family or operating system.
Do I need to know the IO-Link Wireless protocol?
You do not need to develop an IO-Link Wireless stack or implement the time-critical radio protocol. Your host application still defines its device identity, process data, parameters and events, and communicates with the SoM over SPI.
What data can my application exchange?
The SoM supports cyclic process data, ISDU parameter access, and event and diagnostic messages. The preliminary specification allows a configured process data length of up to 32 bytes in each direction.
Do I need to pair again after every restart?
No. The SoM stores successfully negotiated pairing parameters in non-volatile memory. After startup, the host writes its application configuration and can then trigger a reconnection to the previously paired wireless master.
