Product Highlights


Based on the IO-Link Wireless system specifications, the TigoMaster 1T SOM provides an ultra-high reliability of 1 e-9 PER (Packer Error Rate), which is one million times more reliable than other conventional wireless systems.

Low Latency

Enables development of a Master that can communicate with both IO-Link Wireless sensors and actuators at a low latency of 5msec.


Immunity to noisy industrial environments, none line of sight communication, coexists with other wireless networks and with multiple Masters in the same area.

Simple Development

TigoMaster 1T SOM includes an SDK, reference code and samples to enable a smooth development of an IO-Link Wireless Master

Variety of Applications

An IO-Link Wireless Master based on the TigoMaster 1T SOM is used for a variety of industrial applications:
• Collects data wirelessly from multiple IO-Link Wireless sensors for condition monitoring and predictive maintenance.
• Communicates with IO-Link Wireless end of arm tooling and devices on robots/cobots.
• Enables smart and adaptive transport track and independent mover systems by wirelessly communicating with devices (such as grippers and vacuum pumps) on-board of fast-moving shuttles/movers.
• Communicates with IO-Link Wireless intelligent machine tools while rotating rapidly on machines such as CNC, grinding and milling.
