Abstract
This article descibes an enhancement of IO-Link Wireless with an additional safety and security communication layer employing the black channel principle to fulfill safety requirements with respect to IEC 61784-3:2021. An extended channel model based on uniformly distributed segments (UDS) superimposed with the binary symmetric channel (BSC) is applied to simplify the residual error probability (REP) calculation, to detect additional error patterns, and to consider BSC-preserved cryptographic algorithms. Also, the REP with respect to the underlying security layer as well as the probability of failure per hour are quantified.
