Good morning, i have to develop my current software application in order to manage the protocol OPC client/server version 2.x with A&E. I'm so looking for some useful libraries and protocol specifications, or if you have any manual or reference or link to help me. Thank you very much. Best regards. (i'm using LabWindows/CVI 5.0 or Visual Basic)
You can use the datasocket API to connect and talk to OPC servers. There are some examples installed with CVI that demonstrate the use of datasocket functions under ..\CVI\samples\datasocket.
