Hey fellas,
I'm just trying to get a head start on the eventual OS upgrade I'm going to have to do to all my process computers. Windows 7 will be the OS. Currently my Wonderware Intouch HMIs (v9.5) and OEM machine boxes (with OEM software) all run on XP boxes. All OEM apps use DDE to talk to Intouch.
Only one OEM has clearly said that they have a Win7 compatible upgrade that's OPC complient. That one gets to sit at the front of the bus. The others look at me like a deer in the headlights when I ask about OPC, so I'm wondering how reliable DDE is in Win7. Doing some googling, I found out that it's still there.
Anyone care to share their experiences with DDE in Win7? Your insights would be greatly appreciated. Mucho thanks in advance.
