„Last Mile Problem“
Sensors and actuators on the lowest operating level have long since been invested with their own intelligence and with the ability to supply wide-ranging types of information. But despite the diversity of available configurations and interface technologies, what has been missing to date has been an economical solution to address the issue of continuous communication right down to the lowest field level. With the introduction of IO-Link, a standardized interface will be available in the future with the ability to make this type of information easily accessible using conventional 2/3 wire standard parallel wiring.
