Industry 4.0 communication refers to the use of advanced communication technologies to enable machines, devices, and other objects to communicate with each other. This communication is made possible by the use of sensors, wireless networks, and other technologies, which allow for real-time data exchange and coordination between different systems. This kind of communication is essential for the effective operation of smart factories, which rely on automation and coordination between different systems to optimize their performance, and can only be fully achieved with wireless communication as presented by IO-Link Wireless.
