Protinet I/O Controller
There are countless Profinet Masters on the market. On the one hand, standalone hardware solutions or pure software solutions that you can run on the PC.

Profinet is a SIEMENS dominated development and therefore popular in Germany, Europe, China ... So SIEMENS is the right address for you. As an inexpensive device, I would recommend an S7-1211C.

Alternatively, you can install a Beckhoff TwinCAT Runtime on the PC. This installs a Profinet network driver so that you can control Profinet devices from your PC.
