2-15
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 Step7
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
Function MakeSeriesstart-up(FileName As String, Option As Long, Container As
S7Container) As Long
"Option" parameter:
0: Normal series start-up file with general reset
Bit 0 = 1: Series start-up file without general reset. When project contains SDBs, this option is
inoperative.
A general reset is then always executed.
Bit 1 = 1: Series start-up file with PLC restart
Return parameter value:
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 start-up files (e.g. disk full)
Use in script:
If S7Ext.Magic("") < 0 Then
Wscript.Quit(1)
End If
Set Proj1 = s7.Projects("new")
set S7Prog = Nothing
Set s7prog = Proj1.Programs.Item(1) 'if there is only one program'
For Each cont In s7prog.Next
If (Cont.ConcreteType = S7BlockContainer) Then
' Check block container
Exit For
End if
Cont = Nothing
Next
Error = S7Ext.MakeSerienIB("f:\dh\arc.dir\PLC.arc", 0, Cont)
