Here's the code: [code]Dim objHMIGo As HMIGO Dim arrcontent Set objHMIGo = New HMIGO objHMIGo.ListTlgArchive TLG_ARCHIVE_NAMES, arrcontent If (UBound(arrcontent) - LBound(arrcontent) + 1) <= 0 Then objHMIGo.CreateTlgArchive arqTENDENCIAS, TLG_PROCESSARCHIVE End If objHMIGo.ListTlgTag 1, arrcontent, arqTENDENCIAS, strTAG 'arqTENDENCIA is a string with the archive name. If (UBound(arrcontent) - LBound(arrcontent) + 1) <= 0 Then objHMIGo.CreateTlgTag arqTENDENCIAS, strTAG, TLG_TAG_TYPE_ANALOG 'strTAG is a string with the TAG I want to archive. objHMIGo.TlgTagTriggerFactor = 1 objHMIGo.CommitTlgTag End If Set objHMIGo = Nothing[/code] When the code get in the line: [code]objHMIGo.CreateTlgTag arqTENDENCIAS, strTAG, TLG_TAG_TYPE_ANALOG[/code] It gives me a error (see the picture attached) I tryied to generate this with existing and inexisting TAGs, but in either case, the same error occurs. Anybody knows whats wrong? The code seems right to me. Thanks in advance. Attachment erro_wincc.gif (97 Downloads)
