Function MakeSeriesstart-up (FileName As String, Option As Long, Container As S7Container) As Long
Description
Function Magic(bstrVal As String) As Long
Call gives access to certain functions. The function must be called once after server instantiation. The value of
bstrVal can be empty. This initiates a check of the correct STEP 7 version and path name in Autoexec. The
functions are enabled with a return parameter of 0.
Return parameter (-1) = incorrect STEP 7 version
Return parameter (-2) = no entry in Autoexec.bat

Return parameter value:
Use in script
0: Normal series IBN file with general reset.

Bit 1 = 1: Series IBN file with PLC restart
0 = OK
-1 = Function unavailable, call Magic function beforehand
-2 = File name cannot be generated
-4 = Container parameter invalid or container block empty
-5 = Internal error (memory request rejected by Windows)
-6 = Internal error (problem in STEP 7 project)
-7 = Write error when generating series startup files (e.g. diskette full)
