SFC 23 Delete DB |
Top Previous Next |
With this system function you can delete a DB while runtime. You specify the number of the DB that shall be deleted with the parameter DB_NUMBER. Please note that the DB is not opened. It must not have been open in one of the calling blocks either as the call of the currently executed block happened!
The Out-parameter RET_VAL can have following values:
W#16#0000: no errors W#16#80B1: the DB does not exist
The other realized error cases in a S7 are not realized.
