Once you have managed to Connect to PI-AF Database you can connect to a model belonging to that AFDatabase.
Example routine to achieve this is below, this assumes you have a class level variable "AFMod" defined as "AFModel".
Code: Private Function ConnectToModel(ByVal WhichModel As String) As Boolean
Dim ret As Boolean = False
Try
' Check this AF Database contains any models!
If AFDB.Models.Count > 0 Then
' Models available, check AFModel object state, create if required
If (AFMod Is Nothing) Then AFMod = AFDB.Models(WhichModel)
' If model already existed, check it is pointing to correct model
If Not AFMod.Name.ToLower.Equals(WhichModel) Then AFMod = AFDB.Models(WhichModel)
Else
ret = False
End If
ret = Not (AFMod Is Nothing)
Catch ex As Exception
ret = False
End Try
Return ret
End Function
To use in conjunction with the connect to PI-AF Database:
Code: If ConnectToAF("af_server_name", "af_database_name") Then
If ConnectToModel("af_model_name") Then
'Now manipulate model, elements connections, analysis, case etc
End If
End If Principal Consultant
