Good day, I am new and long time passed but currently have similar issue. I need to retrieve program from eeprom cartridge of TSX17 2 4012 PLC. I couldn`t find original software and seems is obsolete. I have found it seems PL7-1 but I receive fatal error. The first welcome/start screen of user interface is ok but as soon as I press ok a fatal error appears. I am trying to set it up in VMWare player and dos is 6.22. If anyone could send me the PL7-2 software would really appreciate it and if any advise related the installation as well welcom.
