PCC is your Wisconsin source for IO-Link technologies and expertise. With our wide array of manufacturers and products we can help you implement a complete IO-Link system. Featuring connectivity to Siemens and Rockwell, our manufacturers masters are easy to configure and cost effective. In addition to all of the sensors we can provide, the I’s in IO-Link, we also have motor starters and LED lights for the ‘O’ side of the system. In addition to the obvious ease of wiring, use IO-Link to easily connect your machine to create a true Industrial Internet of Things (IIoT) system.

IO-Link Overview

IO-Link is a serial, bi-directional point-to-point connection for signal transmission and power supply under any network, fieldbus, or backplane bus. IO-Link is the first IO technology for communicating with sensors and actuators to be adopted as an international standard as described in IEC 61131-9. This technology enables the cyclic exchange of digital input and output process data as well as the acyclic exchange of parameter and diagnostic data between a master and its associated devices. A master is coupled to higher-level systems such as a fieldbus, industrial Ethernet, or even directly to MES, ERP, or cloud-based systems.


There are five basic elements in an IO-Link installation:


  1. IO-Link devices
  2. IO-Link masters
  3. Unshielded cables
  4. IODD files
  5. Engineering tool
