AbvSpu-DB Lists
SUMMARY
CONTENTS
System-DB List
DBs listed here are checked by the AbvSpu on a New= or Restart. The listed files must exist and are initialized with NULL. In case of an error (DB does not exist ) the AbvSpu prevents the execution of OB1. That way the S7 application programmer has got the opportunity to get all DBs (or defined ones) checked and initialized by the AbvSpu on a New= or Restart.
Technology-DB List
DBs listed here are not deleted by the AbvSpu on a Start or Restart . The AbvSpu creates all DBs sourced by the Data Object Types MP, PV and XO via the property “Process Connection”. The information about is stored in the AbvSpu-Database. These DBs are called Technology-DBs also. In some cases these DBs should not be deleted (initialized with NULL) on a New= or Restart. In that case the according DB-Number must be found in that list.
