Communication paths using such unknown components are called ‘Black Channel’ communication paths. With a black channel, data from the sending safety system is launched into an unknown communication mechanism.
Industrial Ethernet Guide - The Black Channel Principle
Jul 25, 2019 · While separate safety networks utilize their independent cabling, the Black Channel Principle allows the exchanging of safety-relevant data and diagnostic information through existing network connections and, as a result, enables faster responses.

Black-channel approach to functional safety - Control Engineering
Aug 10, 2022 · For easier commissioning and better performance, take a black-channel approach to functional safety, combined with the advantages of EtherCAT. A fieldbus safety protocol taking a black channel approach for machine safety communication is becoming more common.
Bus Systems: The Hidden Safety Network | Control Design
May 21, 2012 · The black-channel concept uses a non-trusted transmission system; the network gear is not safety-related. As a result, the primary advantage of the black-channel concept is we can reuse regular network hardware for safety networks without having to modify more than the devices or nodes themselves.
What does Black Channel mean? - Schildknecht AG
Dec 1, 2022 · The black channel principle allows the transmission of process data via network or bus channels. For PROFIsafe, transmission channels are black channels.
Black Channel Communications - Sella Controls
Aug 6, 2024 · Sella Controls has developed a Black Channel Communication system in order to pass safety critical signals between each other. Traditionally a cable would need to be laid.
Black Channel Communication: What is it and How Does it Work?
Dec 1, 2007 · Black channels are very useful for transporting safety related data in a cost effective manner using off-the-shelf components. However, many failure modes need to be taken into account because...
On-chip dual-port memory allows very fast black-channel communication between safe and non-safe sections. To close the servo control loops, the sampled position value δk has to be transmitted with a high resolution, high update rate, and low latency.
Black Channel Communication: What is it and How Does it Work?
Black Channel Communication: What is it and how does it work? This paper will attempt to explain the differences between white and black channel communications and explain in more detail how black channels work.
