do i need to download puttyNo, any terminal emulator that can open an SSH session to a remote device will do.
e.g. a Windows command prompt will also work (using the command ssh admin@192.168.1.10 for example).

I went through the example and ran it, it’s great, but I’m working on an image processing project
I will have my basler camera scan the object and give the coordinates, is there any way to send that coordinate data from python via PLCnext ? Thanks
