It would help if you could say exactly where you get the error message that the file is invalid. Is it when you are trying to export it? Is it when you get into the transfer utility and are trying to download the runtime file to the PanelMate? Did you select a file with a .pps extension to download? Are you only downloading a configuration or are you trying to also download an executive and/or a communications driver?
Everything that is in the printed manuals is included in the help files. PanelMate manuals are printed in a confusing array of different publications. There is a "Configuration Editor User's Guide", a couple of communications driver manuals, a "Transfer Utility User's Guide", an "Online Operation User's Guide", and to further complicate things, a "Runtime Operation User's Guide" for the PanelMate PC. I could be confusing the PanelMate with some other brand of HMI, but I think the manuals are included on the installation CD for the PowerPro software.
