Blocklisting

Blocklisting in industrial automation refers to a proactive mechanism approach employed to ensure the seamless coexistence of several (and variating) wireless networks within the same space. In the setup of IO-Link Wireless, which operates in the unlicensed 2.4GHz ISM band, blocklisting functions by identifying and excluding specific channels that are already occupied or reserved by other networks and systems (such as Wi-Fi networks) to prevent air collisions and interferences.

By mapping out blocklisted channels, IO-Link Wireless can adapt its frequency hopping patterns to avoid conflicts while maintaining high performance and reliability. This enables IO-Link Wireless to operate effectively alongside existing wireless networks, all in parallel to wired connections, thus facilitating optimal communication within industrial environments where multiple wireless and wired systems operate.
