Hi,

Using S71500, SCL, TIA V13.

IN TIA V13 i was told that it should be possible to use Constants to define array bounderies.

After testing this i found it possible to use this feture inside FB or FC blocks using the new local constants.I tried touse global constants in DB or userdefined datatypes buti could not get this to work. Is it true that this feture only works for local constants or do i need touse a different syntax?

See attached screen shoots

Thanx, missed that.

I Suppose, some one does not follow his own recommendation,

FYI :

It will be possible to use global constants to define array bounderies in comming versions of TIA.

It's beeing worked on by developmtent. Idon't know when it will be implemented.
