Hi there guys and Gals.
Here at our plant we have an application that uses VB for visualisation and 300 plc for the logic. I need to insert a command button in the VB to set a variable in the plc. The problem I have is that I dint know where to declare a new variable in the OPC server. Does any one know how to open the OPC item values in simatic.net or how to add a new item
