DB BasicData exists once on every CPU.
Note
Number of DB BasicData
In the TD7 library, DB BasicData ha
s the number DB127 and is also saved there under this
number when the DB is generated for the various CPUs In principle it would be possible to
change the number, but this involves a lot of work and can cause errors in the further
creation of the user prog
ram.
It is therefore recommended to keep the DB number 127 free for the DB BasicData.
