I basically know only eNet IP and serial communication when it comes to automation, and I don't even know the real details, just how to commission the communication so I can get to programming. We have some SIEMENS HMI and PLCs from Germany and it's all PROFINET. Maintenance is telling me that they used to be able to connect to an HMI and have some ability to do a few things, and they used VNC Viewer to do so, but then one day couldn't connect anymore.
I take VNC Viewer (which I've never used before) and I enter the IP address of the HMI and it's supposed to connect. It feels like I'm missing something on my PC, but I'm told that's all they did. I can't get ahold of the builder of the equipment, they suck.
So all other details aside, should my laptop, using VNC Viewer, connect to a SIEMENS TP900 HMI that is PROFINET, without any other software or drivers?
I also cannot ping the HMI, and I'm plugged directly into it, but it's PROFINET!
