TL7 is created to be 100% backward compatible to TL6. Hence, you can generally consider
that:
TL7 = TL6 +Floating point support
That is to say, every feature available on TL6 can be found on TL7, plus the floating point support (which is not
available to TL6).
The program files created by TL7 are assigned with the default extension of .PC7
whereas those created by TL6 are assigned default extension of .PC6. However, there is no
difference in the underlying file structure between a .PC6 file and a .PC7 file. i.e. Both
TL6 and TL7 are able to open each other program files without conversion.
The reason for the difference in the default file extension is so that the programmer
can easily distinguish the programs created for PLC with floating point support from those
created for PLCs without floating point.
When installing the i-TRiLOGI software the installer will register with Windows such
that when the user double-click on a file with .PC7 extension it will be opened by TL7 .
Similarly, double-clicking a .PC6 file and the TL6 will start and open the file.
For user who is familiar with i-TRiLOGI version 6.xx, the quickest way to learn about
the new features available to TL7 is to read the TL7 Programmer's Reference Addendum which
can be downloaded from: http://www.triplc.com/documents/TL7ReferenceAddendum.zip
- this is written as an addendum to TL6 Reference manual to highlight all the new
features.
For users new to the i-TRiLOGI programming, the help files you are viewing should
contains all the documented features of the i-TRiLOGI Ladder + Logic programming software.
Do not be wary if find a lot of references to TL6 or i-TRiLOGI 6.xx as well as
mention of the C:\TRiLOGI\TL6" folder as these are common features that are 100%
applicable to TL7 program. Files that are specific only to TL7 can be found in C:\TRiLOGI\TL7 folder.
