Implementation of an IO-Link interface library component for SoC applications

IO-Link is a new point-to-point communication and connectivity protocol between a master and a sensor/actuator (device), using which it is possible to transfer serial data by way of switching output, using only 3 wires. Till date this protocol has been implemented using generic μCs. In this work a custom model of the Data Link Layer (DLL) of an IO-Link device is proposed. This DLL is able to handle parameter data exchange with the master. Other than the advantages of less chip area and liberty of defining the clock-rate, this model can be used as a library component for future single-chip solutions of IO-Link devices. So this work is primarily a study project on the DLL of IO-Link devices and investigation has been done on its hardware complexity and implementation capability.
