Using WinCC V11 RT OPC Server

sam_krav Posts: 7 Rating: (0)	Hi all. I am working on a project where I want to use Microsoft Access to access some of the data in an S7-1200 PLC. I am using WinCC V11 RT for my HMI. I am looking for examples on how to acess the OPC server that comes with WinCC RT. I can access this data with the Makitron OPC explorer however I have not not been able to come up with any documentation or examples of how to access the OPC server thru VB/VBA.
