Abstract

A slave device for IO-Link communication with a master device, wherein the master device and the slave device operate on a common basic timing, the slave device including at least one Universal Asynchronous Receiver Transmitter (UART) module configured to detect an INIT request sent from the master device during communication setup, calculate an actual timing of the master device from the INIT request and correct an initial timing of the slave device to an actual timing of the slave device based on the actual timing of the master device.
