800xA system used OPC protocol for connecting the CPU. If you want to implement WinCC HMI directly to Connectivity Server, you should use OPC Server/Client architecture. In other case, if you want to get datas driectly from CPU you have to share , what kind of protocol you prefer to use.
Hi, It is very easy to implement in 800xA. In your case, xA is client or server?
If xA is a client, 1. DCOM settings : we need to do DCOM settings in server as well as client side.For these settings refer 800xA configuration manual page num:470. 2.User creation: refer page num : 477. 3.once you complete these settings , try to read their tags from your server using third party client simulator like Matrikon (for testing).If not possible, In wincc side you need to do some settings for accessing their tags.
