folder named CurrentSetup, which is located below the folder you installed PowerMACS in. Keep
in mind that this folder only is used as a temporary working folder. Whenever you save the setup
the PLC project is also compressed and saved to disk. When you go on-line and download a
setup to a system the ZWT2 is also downloaded.
