1. Close the communication software.
2. Enter the folder where Tongda software is installed and find the T0002 folder to enter.
3. Enter the folder gs_bak, and the formula will be backed up here.
4. Just rename the following three documents with the latest date. The file is: 20100310 _ prigs.dat-> prigs.dat, 20100310 _ prics.dat-> PriCS.dat,20 1003 10 _ pritext . dat-& gt; PriText.dat
Where 20 1003 10 is the date number. For example, the backup file name is no100310 _ prigs.dat, and the renaming rule is 201003/kloc-0 _ prigs.dat-. PriGS.dat
5. Then copy the renamed three files to the T0002 directory and overwrite them.
6. Restart the communication software.
This method only supports communication letter versions after 6.0.
