HI there guys does any one know where I can find a tutorial on how to interface VB (Visual Basic) with Step7 using Simatic.Net. Here at our plant our visualisation is done threw Vb And the plc controlling most of the operation. Some hand shaking is done between the plc and VB but I cant find where the linkage is. My Problem is I dont know where these opc item values gets declared. Parts of the VB code will be like

Text1.text = OPCItemValue(0)

I want to know where this opc item gets declared in Simatic.net. Any one out there that can help
