I want to learn about Siemens PLC Siemens programming and WinCC. I have installed TIA portal version 12 in my computer. I want to know if i learn it, then can i also work with Siemens S7? I know its a very basic question, but i really want to know the difference so that my learning direction should be correct.
The basic answer is Yes.
TIA stands for Totally Integrated Automation, which provides a working platform for both HMI and PLC application software including STEP7.
I would recommend using V13 if you can.
