I updated to Trilogi 7.12 build 3 this weekend and discovered a problem.
If you do a "save as" of a PLC program with a date in the file name like PLC 10.3.2017 rev 1 it wont save the PLC file correctly.
If you save it, is does save a file in the desired location, but you can't see it to reload it. If I look with file manager a file has been saved to the directory, but it has the file extension FILE instead of the desired PC7 file type.
If you remove the date with separating periods from the file name, it saves correctly. Windows has no problem with the inclusion of periods in the filename.
In previous versions of Trilogi the inclusion of the date with periods did not cause any problems.
