What do TelePACE files look like? I am trying to search for a project backup.
For standard SCADAPacks using TelePACE firmware:
Really old versions of TelePACE (around 2.80) would have created just a .LAD ladder file. By the release of TelePACE 3.40, two additional support files .CSV and .XML were also saved to keep track of what registers you were monitoring in the register editor and how it saved communication settings with how the software last connected to the controller.
With the introduction of TelePACE Studio (4.xx), a configuration was saved as a .TPJ file along with about ten .XML files. TelePACE Studio 4.xx could open older .LAD files, but only if the . CSV and XML files were present. Old projects with just the .LAD file would have had to have been opened and saved with TelePACE 3.40 to create 2 support files before it could be brought into TelePACE Studio 4. The .TPJ file was very small (about 1k) and would essentially point to all of the . XML files. When sharing programs, customers would often forget to send the .XML support files which required more going back and forth.
Moving on to newer TelePACE Studio versions (5.xx), the configuration was still saved as a .TPJ file but all of the support files were now included as part of the .TPJ file (now much larger that 1k). Improvements in TelePACE Studio now allow a user to open up old .LAD files even if the .CSV and .XML files are missing so the intermediate step is no longer needed.
