The password protection feature is no longer supported on the WinTRiLOGI 3.5 because WinTRiLOGI does not allow uploading of code from the PLC in any case.
In order to utilize the transfer password protection feature you will have to run the DOS TRiLOGI verison 3.3. The DOS TRiLOGI is available on your WinTRiLOGI CD-ROM and you can install it in your PC if your PC supports pure DOS mode. Note that DOS TRiLOGI cannot be used under Windows 2000, NT or XP.
