Chris,

Being able to use IO link with any random CNC controller or device would be very useful to the average joe out there. Supporting the little guys is important these days.

Good question, and the answer is that it depends.

The simple answer is that yes, IO-Link capable distributed I/O or PLCs 'talk' IO-Link to the end device or slave. In many instances, however, the IO-Link capabilities in your distributed I/O card can also be used as a digital input channel. There are methods and products available to utilize your existing sensors in an application while expanding your measurement points with IO-Link enabled sensors.

For instance, you have existing, traditional sensors on your machine. Something in your process has changed and you would like to reconfigure your machine but still use the existing sensors. In this use case, you could use a passive, on-machine junction box to consolidate your wiring. As another example, you don't want to use a large multi-conductor cable to run your signals back to your PLC or controller. In this use case, you can select a passive junction box that contains the IO-Link slave functionality. This device would take all of our sensor inputs and translate the signals via IO-LInk back to an IO-Link card with IO-Link master functionality in your distributed I/O or PLC chassis. The connection cable would be a 4-wire cable, and the passive junction box could handle up to 16 signals, for instance.

IO-Link only works with IO-Link supported devices? Or can it work with any device that one may find on the production line?
