IO-Link Safety and Security

Safety concepts and risk considerations have become increasingly important in engineering due to standards like IO-Link and the dissolution of the OT and IT pyramid, and also due to Industry 4.0. As the underlying communication technology of the IoT, IO-Link uses methods such as synchronous counter, monitoring by "watchdog" and CRC segment to maintain safety in the communication process, at the same time, the key and decryption algorithm are added to ensure security. Through these measures, IO-Link achieves smooth and high-speed operation during the communication process, and also reduces the risk of data abuse due to the bidirectional communication between IO-Link and IT The experiment proves that IO-Link can guarantee its safety and security in the process of data transmission.
