The error number is stored in DW 4 of DBVS+1 and is valid only in conjunction with
the error bit (1 signal).
VL Comparison in progress
Parameter has a "1" signal for the duration of one PLC cycle after all data of the tool
list have been processed.
ENDE End
The parameter has a "1" signal for the duration of one PLC cycle after all data of the
tool list have been processed.

ZWE Intermediate results
GST Initial setting
At the initial setting (F 2.1), the data blocks of the exchange list and the list of mis-
sing tools are set up and the internal status words deleted.
Program example:
With the "Exchange list/list of missing tools" FB, two lists of three data blocks each are gene-
rated:
the exchange list (DB 240, DB 241 and DB 242) and
the list of missing tools (DB 243, DB 244 and DB 245).
These lists contain the data (identification, T number) of the tools necessary for machining but
not available in the active magazine.
