I have a question. I am trying to establish an interface between two softwares (PI process book being my sink in here). My source (data generator) supports Visual basic to export data out of it and visual basic also can be easily supported by PI system. Now, I want to transfer the data to PI server via visual basic. I wanted to know should I use an OPC server (like matrikon DA) to connect visual basics with PI server or I can directly connect visual basic express with PI server?
What will be more appropriate to use direct link or using an OPC (like matrikon DA) in between?
If anybody can hep me I would really appreciate.
