Hello, thad connection between PLC and IO Link, like in attachment it is possible?

Best Regards

Hi kamilbober,

I'm missing some more information about your question, but the answer will be no, it's not possible that way.

In the case of PROFINET, shared access to a device by multiple controllers is referred to as a shared device function. So, assuming you want to connect your PLC to the switch via PROFINET, you would need the shared device function. However, I do not know of any devices that allow shared device with more than 4 controllers, mostly only 2 controllers are allowed.

On the other hand, you would need an IO-Link master that supports shared device functionality.  To be honest, I don't have enough experience with IO-Link to say that this can't be supported by IO-Link, but I don't know of any Siemens IO-Link master that supports shared device.

For more information on Siemens devices that support shared device and other features, see FAQ "Which IO controllers and IO devices support the following functions in STEP 7 (TIA Portal): IRT, prioritized startup, MRP, MRPD, PROFIenergy, Shared device, MSI/MSO, I device, clock-synchronized mode, system redundancy and option handling?".

Kind regards
