OPC UA: Inputs not updating

General Questions
1

I am using OPC UA to connect my TIA portal program to the simulation. I watched the video of the simple conveyor with PLC and OPC UA, but for some reason the inputs don’t update/change in my Tia portal. The outputs work and if I change the inputs with memory bits it works as well, but I need it with inputs.

You could check the device properties in TIA portal. Possibly the process image setting, or the put/get communication need to be modified.

Thank you so much, process image did the trick.
