Interference (Industrial Communication)

In the realm of industrial communication, “interferences” signify unwanted electromagnetic signals or noise that disrupt the transmission of data between devices in challenging industrial environments. These interferences may emanate from various sources, such as nearby machinery, competing wireless signals, electromagnetic emissions, or other electronic devices. To facilitate efficient and dependable communication in such settings, industrial communication protocols, and technologies must be adept at effectively mitigating and managing these interferences.

IO-Link Wireless addresses interferences by incorporating features like a low Packet Error Rate (PER) of 1e-9 for high reliability, a repetition mechanism for critical data, robust Gaussian Frequency Shift Keying (GFSK) modulation, and the use of the 2.4GHz ISM band. It implements strategies such as blocklisting and adaptive frequency hopping to coexist with other wireless networks, effectively ensuring seamless and dependable communication in industrial settings where traditional wireless protocols often struggle to maintain data integrity and reliability in the presence of interference.
