Connectivity in real-time - IO Link, and the Automation Platform Network

(17/09/2019)
It is critical that suppliers of remote I/O systems can connect to the most important networks used in industry today. PROFINET, EthernetIP, EtherCAT® and Modbus are all common networks used in Industrial Automation but how does a manufacturer of machines standardise, when their various customers specify different networks in their factories? Nigel Dawson, head of Business Development Electric Automation at Festo explains.
